Nerd Farmer

RAW POPULATION NUMBERS.
The greatest threat to public lands, private homes, and clean water & clean air, is us and more of us.

People keep having more than the replacement number of children (that's two children per person). On the average: Each person needs to have a child to replace them when they die.

Since men don't actually give birth, that means each women produces 2 children, one to replace herself, and one to replace a man.

So each woman can produce 2 children, and each man can father 2 children, and population numbers stay the same. (Assuming that we are only counting those children who live, grow up, and reproduce).

LOPSIDED POPULATION CHANGE
But just like in wild animals, and animals meant to be sold, there is lopsided fertility, and lopsided survival rates.

Some male partridge father many of the chicks - that means that many male partridge get to father no chicks at all.

Some female bobcats have good territories, and successful hunts, many of their kittens survive. Other female bobcats don't have such good territories, or don't hunt so well - their kittens die.

Some dog breeders choose well advertised types of dogs, pay to get referrals, run good websites, and know how to market their puppies (or they join the pipeline) - they can sell thousands of puppies.

Many pet dogs are never permitted to have a litter, ever.

That is what lopsided reproduction rates means. Each pair don't have two surviving offspring. Many have few or none, others have many offspring.

If the death rates don't match the birth rates, then that species is growing or declining in population numbers. But the "lop sidedness" is not from the raw numbers, but from WHICH animals are reproducing and at what rate.

It use to be thought, among some groups, that lopsided fertility was good - the fit had more offspring, the less fit shouldn't get to breed.

Now, people realize (some people realize) that if one stag sires all the fawns on an island's herd of elk, then all of that years crop of fawns are brothers & sisters.

If that sort of lopsided fertility continues, the whole elk herd on the island will be inbred. They will have no mates available except their own family members - and that is NOT healthy.

On a larger scale, our planet, Earth, is our island.

Animals who die without reproducing, leave their genes in the dust of time.

The genes that march forward into the future, march in the bodies of the next generations.

We ourselves die. Our children die, our grandchildren die. But genes are handed down through time. Therefore, we are all on an island.

When reproduction gets too lopsided, a species looses some of it's store of genes forever. Many of those genes code for things like immunity to disease.

The genes that make for a good computer nerd, probably were their inside of cavemen, and they have combined to produce the type of person who would be good at computers, since before there were computers.

Before computers, a computer nerd was a misfit, an anachronism - now, they shine.

What other combinations of traits make a person a misfit now, but will someday have there place? We don't know.

What if in the 1800s governments only let the best farmers, the best horse-shoers (farriers, blacksmiths), the best cooks, to reproduce? Our species might have lost the genes that it would later need, to combine to make the computer & it's software, possible.

We need diversity even more than the animal species do.

We have so many different niches in our society, and so many new openings that new combinations fit best in. It is the new combinations, at the right moment in time, that are the avaunt guard of science, art, and social adaptations.

Our species has to produce an Edison, a Ford, and a Gates every generation, or real progress fails and stagnation sets in.

Puppies 50 cents.

AWASH IN MASTIFFS! (from pdl #95)



"Why aren't they selling for 50 cents ?"

I'm not a math whiz, so you who are, follow along and steer me back on course, okay?

I know that a healthy giant sized female dog can have 10 - 12 pups per litter and have 2 litters per year. Now, if I start with a pair of mastiffs, and I keep every female puppy and I occasionally trade a male pup for an unrelated male pup, for 6 years, how many female mastiffs will I own?

Let say she has 10 pups per litter, two litters per year, and 10 pups are females and ten pups are males. We can assume that there is always a willing male dog, and that most of the male pups are sold. Lets say that the first first litter was born back in the year 2000 (because it ends in all zeros) .

In 2000, the mastiff pair produce 10 female pups, and we keep them all. To make it easier, we will assume that the first litter of each year is always born on January 1st and is always ten female pups, and that the second litter is always born July 1st and always has 10 male pups. (I guess you'd have to assume I know a lot about reproductive control).

2001, we have the original mother and her 10 daughters, that's 11 females, each having 10 female pups, so we have 110 female puppies born. (I love multiplying by 10, all you have to do id ad a zero behind it).

2002, We have 11 mamas and 110 one year old females, that's 121 mother dogs this year, so we add 1,210 more females.

2003. Mothers: 211 plus 1,1210 = 1,331. More female pups: 13,310. I wonder how many buckets of poo that many mastiff would make each day?

2004. If we haven't gone broke trying to feed all these dogs, we have: 1,331 experienced females, plus 13,310 new mothers = 14,641 mama dogs, and 146,410 new female pups.

2005. Assuming we have the whole town helping us care for all these dogs (or that I'm real clever at farming them out with co-ownership and contracts) we now have 14,641 matron mother mastiff and 146,410 having their first litter, which totals 161,051 mothers, but I'm going to retire the original mother (from 2000) as she might start having litters of only eight soon, so we have 'only' 161,050 mothers, and therefor
one million, six hundred ten thousand, five hundred more female mastiff puppies.

2006. I guess if we breed all the females (except the 10 due to retire this year), we'd have like 17 million female pups and then like 17 million male pups. Lets not breed them anymore. Call dog rescue and ask them to come get the nearly two million unsocialized grown mastiffs we don't need anymore.

---------------

So why do puppies cost so much when people use to hang "free puppies" signs on corners, and people use to sit in front of stores all day long to give away a litter of puppies?

I don't believe it was because the pet owners wanted to never have a litter of puppies, but because people who sold puppies for money, sold their puppies only with mandatory spay/ neuter contracts.

Now, one can make money selling some kinds of puppies - but few people do, why?

Is dog breeding becoming unionized?

Sharing Our Food.

Is the woman in the photo happy? Yes.
Is she happier than the hunter out trudging through the woods? Maybe.

Nobody says that most hunters hunt in order to prevent animals from starving, but our culture has taught them that hunting is fun. Why? Because somebody has to do it.

I don't fault the coyote for hunting, nor the bobcat. Should I fault the man who hunts, even though animals would suffer worse without him?

Sometimes life can't give you nice answers. Until a better way of animal control is found, hunting is the way people thin the herds.

Too Much of a Good Thing.

Did you ever sit down tally up the uses purebred dogs are said to be bred for? I have, and I found mostly hunting uses.

There are dogs who track animals, sprint after animals, fight animals in a burrow, and wrestle wild hogs. There are even dogs who are bred to specialize in hunting birds. And retrievers who fetch shot birds. When did rifles become accurate enough to shoot birds?

From ancient sprinting dogs carved on Egyptian tombs to duck retrievers, people have been using dogs to get meat, and to kill wild animals who eat our crops.

Hunting is bloody, it hurts and kills animals, and it ruins the woods for hiking because of all the bullets.

But deer would reproduce to the point that they were starving, and would kill the trees, and make roads unsafe to drive on in some areas. I have driven roads with deer running across them and the animals run right out on the road. A car crash into a deer can kill people. If deer were starving, there would be even more on the roads and in towns.

Yes they are beautiful, and I love seeing them with their little fawns, but I like seeing them alive, not starving, and not laying dead by the road where they have been hit by a car.

Until there is an inject able or edible sterilizer, mice, rats, rabbits, raccoons, and deer will keep reproducing.

At the end of winter, the number of animals is the number that the land can support in winter.

Then spring comes, and plants grow and there is more food for the animals. They have babies, and they eat up all the extra food in the summer and fall, (including wheat, corn, and vegetables) and then in the winter, food levels return to winter level and animals starve.

It's sad. But hunters kill some of the over population, maybe that's quicker than starving. It is sad. But I can find no answer that I like.

There is a difference between killing an animal and enjoying killing on animal. Like I have swatted flies and mosquitoes, and squashed roaches, but I don't enjoy it. I would find it a bit gross if someone really enjoyed killing bugs.

I think that's a problem I have with hunting. I can't find a replacement for it, coyotes, foxes, lynx maybe? Wolves and mountain lion for deer? But people don't want animals big enough to kill deer near their homes.

And we can't get rid of all the deer, because bushes would grow, die, and become tinder for fires, which would kill our wood industry, ruin the woods, and kill more animals. Bushes would grow where the trees were and without deer, we would be facing problems each year.

And if there were less deer in the woods, there would be more food for mice, rats, and rabbits - we would just be trading one problem for another.

Life doesn't always give us easy choices. For now, all I can think of is managing the situation as best we can.

Mouse x


They may be small, but they carry disease, and they over-produce.

How do you tell a mouse that he needs to wear a condom?

I like cats too, but you can have too many cats, just like you can have too many mice.

What many people don't understand is that just as people in houses can have too many pets, an imbalance in nature causes too many animals of one species - except that in nature, many of the animals will starve, or die migrating to find food - like where bears or coyotes come into towns looking for food.

Rabbit Video.

1) This first video clip shows the factual problem in Austrailia with rabbits. The thickest part is almost 60 seconds into it. Eagles are near the end. Once the land reaches it's carring capacity, animals start to migrate and then starve, or force other kinds of animals to starve.

Pest control:

I have come to terms with the fact that if someone doesn't thin out the herds of deer, rabbits, rats, mice, other rodents, hogs, and flocks of birds, we would soon have no farm crops for ourselves, our friends, and our families.

I like wildlife, but I need food too, and so do you.

I've looked at this from every angle, and the only thing that would work, is for people worldwide to have smaller families. The wildlife can't compete with humans destroying their forests to make houses and fields for more of us. Nothing else will protect animals.

As every bit of usable land becomes used, even cats & dogs will be seen as a threat to somebody's food. It is possible that starving countries could seek to destroy pets in agricultural countries to make more food for their growing number of people. Worldwide food shortage, or high food prices due to high demand, is a strong motivator for war, especially more modern forms of warfare.

If we had one tenth or even one fourth of the people we now have to feed, we could be tolerant of animals eating some crops. I remember reading somewhere long ago about planting 3 plants for every plant you want: one for the bugs, one for the birds, and one for yourself (author unknown).


We haven't been that tolerant in a long time, we have pesticides for the bugs, which one way or the other hurts the number of birds. But poisons that kill rodents can kill us, dead rodents in our fields of crops decomposing with a belly full of chemicals that are harmful us, doesn't sound like a good idea to me, but what other choice is there?



Do you have any idea how much it would cost to pay people to kill rats? And deer? deer are so good at hiding, it might take one person 2 days to get one deer.



Deer are pretty, and graceful, and I love them, but when they over multiply they starve, and starving deer get desperate, they roam looking for food, they cause car wreaks because they run in front of cars, and in hunger, the deer kill trees and plants, and get sick and spread disease and parasites, like Lyme's disease.



How can we keep the numbers of wild animals down, without spending massive amounts of money or loosing our food?



There is no additive we can leave out to sterilize them, and it is not possible to spay/ neuter all the wild rabbits and rodents.



Maybe you would like to help give these wild animals a quick death instead of a slow one? A large number of wild animals die every year, because they have so many young.



If a patch of land will support 100 deer in the winter, but in the spring the 50 female deer have a total of 75 young, then there are 175 deer in the spring, on a patch of land which will only hold 100 deer in the winter. 75 deer must die before winter.



Either they roam and starve, damaging the trees and plants the other animals need too, endanger traffic, and eat our crops, or somebody has to go out and give them a quick death.

Without predators, rodents would eat everything edible.

If you can think of a better way to convince people that it is fun to go out and get rid of rodents and rabbits who invade our crops, great, but until you can get your method of controlling rodent numbers to work, the current plan is to call it "hunting" and get people to spend their free time out in the areas near farmlands and woodlands shooting wild animals who don't shy away from people.


Myself? I would rather play on a computer than sit quietly in a deer stand for the weekend.

And I don't like shoveling snow (which is light weight), so I know that I would not want to dig rodents out of holes, and you can have all the dead rats you want, I wouldn't eat them, and I certainly wouldn't clean them and cook them.


And I have no intention of buying a catch dog, loving the dog then risking it hunting hogs. Hogs grow big. But if you want to get rid of the feral hogs, I guess that's okay, maybe even good. A hog is a hog. The ones sold in the store maybe never got to run free, maybe the feral ones were luckier, maybe they weren't. If the feral ones were hungry and diseased, maybe the ones at the hog farm were happier, maybe they weren't, I don't know.


But I do know that female hogs have litters before they are full grown, and keep having more litters. The only way to keep the quality of life up for feral hogs, is to keep their numbers down. Nobody has found a better way to do that than hunting.

Maybe someone wants to go out and castrate feral boars, and implant IUD in feral sows? You don't get just how big, aggressive, and strong jawed hogs are? That's not safe. And fat hogs tend to absorb the anesthesia.


If you have a better idea, type away, because nobody else has found one.

Except maybe this: instead of us going out and thinning the herds, let's convince other people that building a little platform on a tree, and sitting there without moving, no radio, no phone, no talking, no smoking, no noise, no moving around for two days is so much fun that they will lug guns, ammo, and hunting stands for hours to get to a place with less people so they will have a chance to shoot a deer.

Let's convince people, not to get a nice friendly dog, but a pack of hyper active hunting dogs, and let them get up before dawn and drive to the farm edges and chase rabbits, hares, and rodents?

Let's see if terrier people will spend their day having their dog corner a rodent underground, and then have the person dig down to the rodent to destroy it. I like that better than rat turds in what's left of our food, because we can't get rid of enough rats. Rodent droppings and hairs are in human food. Not enough people are convinced that rat hunting is fun.



What can I say? Breed more Rat Terriers and Feists, and get their owners to kill more feral rats.

Did you see that video of rats in the fast food place? Have you ever seen films of rats and rabbits when they have a good year? - there are videos of vast swarms of rodents in Australia, which have been shown on TV occasionally.

That's what happens when an animal has so many young so often, and nothing slows them down, they form herds that eat their way forward across the land.Permission to crosspost.

BOOM & BUST REPRO

Tried & True, but maybe not nice.

Message #49 of 148

KINGDOM OF HUNTING DOGS. Hunting with dogs is permitted to control the number of rodents who would spread disease, eat crops, gnaw, or damage the environment. Rodents, including rabbits, reproduce quickly and in huge numbers, which if unchecked, would multiple to the point where they would eat all the grain and vegetables before the crops even left the farm.

We would have nothing to eat, would starve to death, and become extinct, if rodent numbers were not kept down. Some other animals are a threat to us directly, or again, because they reproduce too fast, and would eat our crops.

Deer reach the maximum number the land can sustainable on a year to year level, in late winter. We will call this number 100, as it is 100% of what the land will support in winter. Then comes spring. If the number of female and male deer are equal, and each female deer has two fawns, the number of deer would be 200, double what it's carring capacity will be next winter.

For the deer not to starve to death in the winter, half the deer population has to die before winter.Nasty, but true. Some animals quickly reach the maximum number the land will support, and for each young that survives after that, an adult deer must die. There is a finite number of deer that the land has food for.

If left on their own, the starving deer would start to chew trees and kill the trees. The deer would die, and trees too. Starving deer would migrate onto roads, where they would get hit by cars, the deer would die of the injuries and sometimes the people in the car too.Hunting can provide a quicker death for the deer than starving.

Shooting deer in the fall, after the food plants have quit providing food for the deer, is a quicker death for the deer than starvation. In some areas, hunting has reduces the number of deer, so that the remaining deer have a comfortable life. In other areas, the number of deer is high for what the land will support, the deer are hungrier, less well nourished, and often can only have one fawn per year.

If the land will hold support 100 deer from year to year, and that is what is on the land at the end of winter, and then 50 fawns are produced in the spring, 50 deer will die before the end of the next winter, whether by being shot by hunter, killed by wolves or mountain lions, or, most likely, by starvation.

Once the carring capacity is reached, for each fawn born, one deer must die, because the land will only feed a set number of deer. If the land will only feed 100, and 50 more are born, either those 50 fawns must die, or, if they live and mature, 50 adult deer will die the next winter. The land can only feed so many animals.

If you have a better idea than making a sport out of it, so that hunters will go out and put down the extra deer, then post your idea, the world is waiting, because nobody else has thought up and answer yet.

The system now, is that hunters kill the extras deer off in the fall so that the deer don't starve in the winter.Please don't suggest we grow food for the deer, because the deer that live, then have more babies, the babies are grown and have babies of their own at 1 year old.

The world couldn't grow enough food to feed all the deer, because no matter how much you fed them, you'd have to double or at least half again that number of tons of feed the next year.

Rats, mice, rabbits, and other rodents reproduce even quicker. It just isn't possible to spay & neuter them all.

If the numbers weren't kept down, we would starve, and so would they because they would reproduce to the carrying capacity of the land, then for every baby rodent born, one rodent would have to die, either the baby, or if it lived, then an adult rodent. Long before that level was reached our croplands would be chewed down stubs, and rodent carried diseases would infest them and us.

The other day, I was thinking about the idea of hunting, and what could be done to stop it. I can't find and answer which will work. Either we have foxes, coyotes, and bobcats that kill the rodents, or the rodents starve, or we starve and then the rodents starve, or people kill the rodents. Then I saw this cute little squirrel.

Obviously, people had fed him, and he wanted a food. I went back and got him some peanuts, and left them at the base of the tree that I had seen him at. I felt good about that. But we can't apply that to a larger scale, because the rodents saved, reproduce, and then many more rodents need much more food the next year.

Unlike deer which have 1, 2, or 3 babies per year, rodents have huge litters. Deer have only one litter.

My pet mice had 10 to 12 babies every 21 days until I removed the male. They averaged half a baby per day, per female mouse. They were well fed, and they got nuts and seeds, and bread sopped with milk; starving mice would have less surviving babies.

While deer are pregnant from fall to spring, mice only take 21 days to produce a litter. Deer don't have their first fawn until they are a year old, mice only take months to reach maturity.

When the number of wild animal in an area gets too high and the animals nutrition become poor, disease often starts to spread among the animals.

We can't let the number of animals in an area grow to the point where animals suffer, starve, and get disease. Not just to save the animals from sickness, but to save ourselves from the diseases that overcrowded wild animals can spread.

Now you say, "oh but the hunters don't hunt to help keep animal numbers down so they don't starve" and you are right.

But if hunters stopped hunting, we would have to trick people into finding hunting fun, so they would go out and do free pest control around farming and agricultural areas, and go out in the woods, climb hills, cross cold water streams and sit quietly to shoot animals, and then carry the carcass out of the woods.

Do you have any idea what it would cost to pay people to do that if they really looked at what they were doing and said "gee, lugging a rifle up and down hills, getting wet, sitting in the cold, carrying a dead animal out, ya know what? this is NOT fun, I should be paid to do this crop protection"?

Somebody or something has to kill off the animals who there is not enough food for. If you don't want to do it, who will?

Yes, hunting goes too far sometimes with canned hunts and raising animals to turn them loose to be shot. Or misusing hunting dogs in a way that is a hunting sport, not hunting to quickly dispatch an animal.

Hunting can't end until over reproduction of wild animals does. And deer and rodents can't be all killed off, because our forest produce lumber.

Many forest are clear cut logged (no trees left) and baby trees are planted in rows like rows of corn. Somebody has to kill all the weeds. The cheapest somebody to get to do that are animals that eat weeds.

But come winter, the weeds die off, and their isn't much food for the animals, then comes spring, more weeds, then more animals, it just cycles over and over, birth and death, seeds and dried up weeds.

You can't throw out the old system (hunting) until you can up with a better plan, and use that plan to show that it works.

So far, nobody has a better plan. I like the idea of having big pools of indoor water, like swimming pools and using electricity to feed plankton (tiny, little things that live in seawater) in the pool, then harvesting the plankton.

Of course, nobody has done that yet, and while that might free up cropland, it still wouldn't solve over-reproduction of wild animals, and boom & bust population numbers.

Every see video of mice or rabbit numbers in Australia? Every once in a while, it will be dry in Australia, and the predators will be few in number, then rain will come, and the rats, mice, or rabbits will multiple, eat all the food, and start traveling in huge packs munching all the food stuffs ahead of them.

It would just about be worth going to Australia to see it, but it only happens sometimes, not every year. I have heard from one tourist who said the bus drove thru a road covered with dead rodents (I forget if they were rats or rabbits or mice) and the bus had to drive slow so not to slip on all the dead bodies, and it took a very long time, to drive thru the herds of hungry rodents.

Maybe I could skip that.That out of the way and said, I like wild animals. I like foxes, and I don't understand why they are still killed. We don't have lots of farms with loose chickens anymore. Foxes eat mice, mice eat grain and vegetables and spread disease. Foxes are good, now that we don't have loose chicken anymore.

Until somebody comes up with a better plan, that works, hunting will have to remain. Maybe global warming will make it summer all year? But don't wait on that one, it might dry things out.

Rat pit.







Most of our breeds of dogs today, descend from hunting dogs.
Towns use to employ a man called a rat catcher, whose job it was to kill rats, but towns still had rats, and the rats spread disease, so...

In order to encourage the public to help get rid of the rats that were spreading disease, the government made rat killing a sport. People would bet on how many rats a dog could kill in a set amount of time.

To supply the rat pits, people had to catch rats (There were no wire cages then, so they could not cheat by raising rats).

.
.
The plague was spread by fleas including fleas that lived on rats.

It is estimated that 1 out of every 4 people in Europe was killed by the plague.

Governments did their best to stop rats from breeding - picking up the garbage and burying or burning it helps keep down rat numbers, as the rats have less to eat.

Somebody even dreamed up a tale of a great way to get rid of rats - The Pied Piper. He played a song so sweet that the rats fell into a trance and then the Pied Piper led them out into the sea, where he, still playing music on his pipe, got into his boat. The rats followed the music and drowned.

Good story but rats don't follow music and they DO swim very well.
Watch this video on MODERN 'rat' pit 'killing', how many 'rats' does the terrier kill?
