The more the United States adds people, the more water we use, the more food we eat, the more land we cultivate, the more fertilizer we spread, the more energy we burn--thus, the more we pollute the air, land and water.
Example: the Mississippi River spews millions of gallons of toxic water into the Gulf of Mexico 24/7 to create a 10,000 square mile dead zone. Toxins include fertilizer runoff, insecticides, herbicides, household wastes, sewage and a host of chemicals. Vertebrates cannot live in it, thus, our poisons created a dead ocean area. As humans' ultimate toilet, worldwide, our oceans suffer horrific consequences to marine life, plankton and fisheries.
Most Americans cannot 'see' overpopulation. And, their leaders fail to address it. Everyone finds it easy to avoid, deny or reject. But day by day, week by week, month by month and year by year--overpopulation impacts every American--and it's growing worse as we add 3.4 million people to the U.S. annually, predominantly by immigration. Ironically, those immigrants stream into America from overpopulated countries that add 77 million people, net gain, annually to the planet. Next destination: 100 million people added to America by 2035. That's 26 years from now.
Even more astounding, most Americans cannot get their emotional or mental arms around what they face with an added 100 million people. Thus, they avoid talking about it and the media ignores it. They may avoid it, but in the end, overpopulation will not avoid anyone.
