It is c bothed the dinosaur- nursery extinction theory. It saysthat a climate change via the greenhouse effect killed off the dinosaurs. My opus takes this proposed theory and relates it to the world today. Some of thethings that happened back whence atomic number 18 also happening now, and if the dinosaur-greenhouse extinction theory is indeed true, then we are also in risk of dyingfrom the greenhouse craniate killing mechanism, abrupt atmospheric changes,and the other effects caused by the increase greenhouse effect and peopleshould know about the consequences of what we are doing to the earth. My paperexamines the similarities occurring in the two time periods and the possibleresults that we may soon be facing in the very near future. I am hoping that film to the inevitable danger that we are soon going to be facing, pull up stakesspark action and concern within whomever reads my paper. It is a problem thatwe all have tended to shrug off and not worry about, but if we dont offsetworrying about it soon, there go out not be anyone just about to worry about. Thetime for action is now. We may still be able to change the future.      Humans Soon to Become Extinct? Can it be?     Roughly sixty-five million years ago a horrible extinction of globalproportions hit the planet earth. This global extinction was so severe that ithas defined the boundary between two periods of geologic history called theCretaceous and the Tertiary periods. All but a few mammals on land and waterbecame extinct. (McLean,1978,p.1) The best known of these extinct animals fromthis mass extinction are the huge and mighty dinosaurs. What killed them nobodyreally knows and probably will never know, but scientist havent hesitated totheorize about it. There have been theories ranging from kind involvement todisease to even aliens. However, of all the theories of the so called K-Textinctions, the single most accepted theory is called The Volcano GreenhouseTheory. This theory states that a chemical chain of volcanoes in India, called "theDeccan Traps", released vast quantities of the greenhouse gas carbon dioxideinto earths atmosphere lodging heat from the sun, (McLean,1988,p.2) andturning earths surface into "the hot, sterilizing, hell of a major greenhouse."(McLean 1981,p.1) If the dinosaurs did in fact die from the Volcano-Greenhousetheory, then we are also in danger of becoming extinct from the Vertebrate
