Earth Day 1970 was the largest public "demonstration "in history. The day featured scary predictions about the future. All turned out to be wrong.
WHAT ACTUALLY HAPPENED FROM 1970 to 2020 ? (all data are from 1970 to 2020)
Ont occur,as had been predicted in 1970.
The global fertility rate in 1970 was 4.8 children per woman; it has now half - 2.4 children per woman. In 83 countries, including the U.S., which add up to half the world's population, fertility is below the replacement rate of 2.1 children per woman.
World food production more than tripled, with average per-capita calories supplied rising from about 2,400, to nearly 3,000 per day. U.S. corn yields since 1970 rose from about 60 bushels per acre, to nearly 170 bushels now.
The world did not run out of copper, lead, zinc, tin, gold, silver, and especially oil.
Since 1970, EPA data shows that as U.S. Gross Domestic Product grew nearly 275%, vehicle miles traveled grew 191%, population grew 60%, and energy consumption grew 49% ... the aggregate emissions of six key regulated air pollutants declined 74%.
Today over 92% of community water systems meet all health-based standards, 24 hours a day, 365 days a year.
In 1970, over 40% of the nation’s drinking water systems failed to meet basic health standards.
The amount of CO2 in the GLOBAL atmosphere has increased by 25%, from 328 parts per million in April 1970, to 410 ppm. But U.S. carbon dioxide emissions declined 20% since 2007.
Environmental doom and gloom stories still get headlines in newspapers, magazines and on TV. The truth is the U.S. environment has been improving.
Dire prophecies, of the first Earth Day, have been proven wrong. For environmentalists, it seems that a belief in the end of the world, from whatever environmental crisis is popular at the moment, is a primary source of their happiness !
