In 1969, President Nixon issued to Congress a "Message on Population." Referring to the expectation of the time that the U.S. population might exceed 300 million by the year 2000, he said:
This growth will produce serious challenges for our society. I believe that many of our present social problems may be related to the fact that we have had only fifty years in which to accommodate the second hundred million Americans. In fact, since 1945 alone some 90 million babies have been born in this country. We have thus had to accommodate in a very few decades an adjustment to population growth which was once spread over centuries. And now it appears that we will have to provide for a third hundred million Americans in a period of just 30 years.
THIS IS TOP TEN:
As the human population grows and the rich countries continue to consume resources at voracious rates, we are crowding out, poisoning and eating all other species into extinction. With the world population hitting 7 billion, the Center is marking this milestone by releasing a list of species in the United States facing extinction caused by the growing human population. The 10 species represent a range of geography, as well as species diversity — but all are critically threatened by the effects of human population. Some, like the Florida panther and Mississippi gopher frog, are rapidly losing habitat as the human population expands. Others are seeing their habitat dangerously altered — like the small flowering sandplain gerardia in New England — or, like the bluefin tuna, are buckling under the weight of massive overfishing. Still others, like the polar bear, are facing extinction because of fossil fuels driving catastrophic global warming.
The Florida panther once ranged throughout the southeastern United States, but now survives in a tiny area of South Florida representing just 5 percent of its former range. It was listed as an endangered species in 1967 because of habitat destruction and fragmentation through urban sprawl. Large numbers of panthers died as the expanding network of roads connecting Florida’s rapidly growing human population spread throughout its range. As of 2011, there are only 100 to 120 panthers left.
As Florida’s panther numbers plummeted, the state’s human population nearly doubled over the past 30 years. Recent development patterns pose extreme threats to panthers. As the Florida coasts approach full buildout and have become unaffordable to most people, development has moved inland to the same places panthers retreated to as safe havens decades ago.
