At first I thought you were the dumbest person here, but now I think you're the dumbest person on Earth. Not on Earth right now, the dumbest person on Earth ever.
The population of EVERY species on the planet EVER has been dictated by environmental factors. From bacteria to fungus to plants to insects to mammals, the population CANNOT exceed the supply of whatever resources are necessary to support life. If there is food to support 10 people you can't have a sustainable population of 100. If there is water for 1,000 birds the bird population can't grow to 5,000. How did all those animals that proceeded us and grew at a faster rate than us not grow at a rate that allowed them to inhabit every square inch of the planet before humans ever evolved (or in your case, remained remarkably apelike)? Were they good planners? Did they practice safe sex? Did they hate kids? No, fucktard, they could not outgrow the environment that supported them. No food, no population growth. You can view that pretty easily by observing wild populations (well, we could see it, you would lack the brainpower to notice or process the information). Larger species require more food and more water and that limits how many of them their habitat can support. The lion is the king of the jungle, so why are there more birds, rodents and reptiles in the jungle than lions? Because the lions can't outgrow their food supply. If they do, the excess population will starve until the numbers reach stasis.
