The floods in the Yangtze River basin are the worst in 44 years. Official figures indicate that more than 2,000 people have drowned and 13. 8 million have been driven from their homes. Crops have been destroyed on 4. 5 million hectares, 3% of China's total cropland. Some factories have had to shut. The transportation of goods and people has been disrupted. The overall effect on China's economy will be felt for many months.
Floods during the monsoon season in southern China are a regular occurrence. But there's a human hand in this, in the form of deforestation and intensive land development. The Yangtze basin is home to 400 million people. With such a density of population, the human pressure on the land is intense. The Yangtze basin has lost 85% of its original forest cover. The forests once absorbed and help huge quantities of monsoon rainfall, but now there's much greater runoff into the river.
The construction of buildings and roads in the basin is increasing at a staggering pace. And land hunger is forcing more and more homes to be built on the river floodplain. The extent of factory construction also defies the imagination. By a rough estimate the size of the industrial workforce in the basin would be at least 50 million. With the average factory in the private sector employing fewer than 120 people, this means half a million factories. Collectively these homes and factories cover a vast area, further reducing the capacity of the land to absorb rainfall.
Due to higher global temperature and more intense monsoons, the Yangtze basin may well be one of the areas getting some of the additional rainfall. We can expect even worse floods in the years ahead. If the basin adds another 100 million people, as projected, in the next few decades, China will need to build another 25 million homes. As industrialization continues at a rapid pace, factory and road construction will also continue, further reducing the area of land that can absorb water and increasing the amount that will ultimately flow into the Yangtze.
With the international community unable to agree on a meaningful effort to reduce carbon dioxide emissions, rising atmospheric levels of this greenhouse gas promise even higher temperatures for more evaporation, more rainfall and even stronger monsoons. The 400 million Chinese living in the basin are beginning to feel directly the effects of altering the environment. This should be a warning to the international community to begin working together to lower greenhouse gas emissions before climate change affects even more people.
What was the purpose of Earth Day? How did it start? These are the questions I am most frequently asked.
Actually, the idea for Earth Day evolved over a period of seven years starting in 1962. For seven years, it had been troubling me that the state of our environment was simply a non-issue in the politics of the country. Finally, in November 1962, an idea occurred to me that was, I thought, a virtual cinch to put the environment into the political "limelight" once and for all. The idea was to persuade President Kennedy to give visibility to this issue by going on a national conservation tour.
I flew to Washington to discuss the proposal with Attorney General Robert Kennedy, who liked the idea. So did the President. The President began his five-day, eleven-state conservation tour in September 1963. For many reasons the tour did not succeed in putting the issue onto the national political agenda. However, it was the germ of the idea that ultimately flowered into Earth Day.
Six years would pass before the idea that became Earth Day occurred to me while I was on a conservation speaking tour out West in the summer of 1969. At the time, anti-Vietnam War demonstrations, called "teach-ins", had spread to college campuses all across the nation. Suddenly, the idea occurred to me — why not organize a huge grassroots protest over what was happening to our environment? I was satisfied if we could tap into the environmental concerns of the general public and infuse the student anti-war energy into the environmental cause, we could generate a demonstration that would force this issue onto the political agenda. It was a big gamble, but worth a try.
At a conference in Seattle in September 1969, I announced that in the spring of 1970 there would be a nationwide grass-roots demonstration on behalf of the environment and invited everyone to participate. The response was electric. It took off like gangbusters. Telegrams, litters and telephone inquiries poured in from all across the country. The American people finally had a forum to express its concern about what was happening to the land, rivers, lakes and air — and they did so with spectacular exuberance. For the next four months, two members of my Senate staff, Linda Billings and John Heritage, managed Earth Day affairs out of my Senate office.
It was obvious that we were headed for a spectacular success on Earth Day. It was also obvious that grass-roots activities had ballooned beyond the capacity of my U. S. Senate office staff to keep up with the telephone calls, paper work, inquiries, etc. in mid-January, three months before Earth Day, John Gardner, Founder of Common Cause, provided temporary space for a Washington, D. C. headquarters. I staffed the office with college students and selected Denis Hayes as coordinator of activities.
Earth Day worked because of the spontaneous response at the grass-roots level. We had neither the time nor resources to organize 20 million demonstrators and the thousands of schools and local communities that participated. That was the remarkable thing about Earth Day. It organized itself.
