GEORGE PLUMB: WHILE HUMAN POPULATION GROWS, WILDLIFE DECLINES
See original/source content: http://vtdigger.org/2014/
On Oct. 1st, it was announced that the World Wildlife Fund had published the Living Planet Index. It revealed that the population of vertebrate species – mammals, birds, reptiles, amphibians, and fish – on this planet has plummeted by 52 percent just since 1970. Thirty-nine percent of this decline was by terrestrial species and the other 61 percent by water species. At the same time, our own demands on nature are unsustainable and increasing. We need 1.5 Earths to regenerate the natural resources we currently use; we cut trees faster than they mature, harvest more fish than oceans replenish, and emit more carbon into the atmosphere than forests and oceans can absorb.
It is hard to believe that half of the animals on this earth have been destroyed in just the past 44 years, only part of my lifetime and less than the lifetime of many people alive today. During the same period the world populations of human beings have doubled from 3 billion to 7 billion, the U.S. population has increased by 50 percent, from 200 million to 300 million, and Vermont’s population has grown by 25 percent, from 500,000 to 626,000. The announcement briefly made some of the news, but since then it has been totally neglected.
