Our fragile earth faces outer space terror. Two billion years ago, an asteroid hit earth, creating the Vredefort crater in South Africa. It has a radius of 118 miles, making it the world's largest impact crater. In Ontario, there's the Sudbury Basin, resulting from a meteor strike 1.8 billion years ago, which has an 81-mile diameter, making it the second-largest impact structure on earth. Virginia's Chesapeake Bay crater is a bit smaller, about 53 miles wide. Then there's the famous but puny Meteor Crater in Arizona, which is not even a mile wide.
I've pointed out only a tiny portion of the cataclysmic events that have struck the earth -- ignoring whole categories, such as tornadoes, hurricanes, lightning strikes, fires, blizzards, landslides and avalanches. Despite these cataclysmic events, the earth survived. My question is: Which of these powers of nature can be matched by mankind? For example, can mankind duplicate the polluting effects of the 1815 Tambora volcanic eruption or the asteroid impact that wiped out dinosaurs? It is the height of arrogance to think that mankind can make significant parametric changes in the earth or can match nature's destructive forces.
Occasionally, environmentalists spill the beans and reveal their true agenda. Barry Commoner said, "Capitalism is the earth's number one enemy." Amherst College professor Leo Marx said, "On ecological grounds, the case for world government is beyond argument." With the decline of the USSR, communism has lost considerable respectability and is now repackaged as environmentalism and progressivism.
