Animal Overpopulation Research Paper

What I have learned is that overpopulation of animals should stop if more people adopted pets. Some pets are lucky because some of them get adopted by and get put in good homes. But about 6 million dogs or cats enter the animal shelter every year in the U.S. Another fact I have learned about the overpopulation of animals is that people buy more pets from breeders than adopting one from the animal shelter.
