Global Warming

Extracts from this document...

Introduction

Global Warming "Millions of years ago, disaster hit Earth, killing 95 per cent of all species. What caused it? Conditions that was chillingly similar to todays." (Lavers) According to the President of USA and his flocks of corporate sponsors, the prospect of so-called "global warming" is nothing that America should worry its pretty little head about. Many people buy into this analysis, dismissing the alarming new trends as merely changes in weather that happen all the time, or actually proclaiming that they would be glad if the earth were a little warmer - just like a day at the beach! What few people realize is that global warming is no longer even a theory; it is a fact. Moreover, it's not just a matter of the earth getting a few degrees warmer in the summer; the prospect of global warming truly is a threatened end to life as we now know it. Unless steps are taken to stop the current progression of events, and even in spite of such steps we may try to take, the vast majority of the evidence shows that the Earth will continue to grow warmer, with widespread and even catastrophic results. Global warming is a hot and widely debated topic. Speculations about the truth and facts of global warming have been questioned for years by both corporate business and respected scientists in our society. ...read more.

The oceans would stagnate, destroying the entire marine ecosystem. The death of other ecosystems would follow. Forests, wetlands, farmlands and mountains alike would all be challenged. The life cycles and habitats of plant and animal life would be radically altered. Increased moisture and heat, in addition to damaging many species, increases the population of disease bearing mosquitoes and other insects. Between flooding and coastal erosion, severe weather, disease, loss of farming, hunting, and grazing land, and the loss of inhabitable territory, the very existence of the human race would be threatened. Such a global catastrophe has happened before, according to the fossil record, 250 million years ago, at the close of the Permian period. The earth underwent mass extinction on an unequaled scale. Approximately 95 percent of all species became extinct, including such hardy creatures as insects and fungi. "What agent of destruction could have wiped out 95 per cent of all species on our planet? The answer emerging from recent research is disquieting, given our current environmental predicament: it seems that the greatest disaster in the history of life was brought about by the combined effects of global mixing and global warming." (Lavers) Nothing quite that drastic is certain to occur again in the near future. The global temperature change during this time was around 6 degrees Celsius (C), while only the most radical analysis of the next hundred years suggests that such a change is in the cards. ...read more.

Conclusion

Children died beside them. Hundreds of animals species are going hungry and even becoming extinct due simply to environmental change. Polar bears, driven from the broken ice floes wander down into civilization, while hundreds of seals starve. "All around, weather has become more extreme. Wet regions of the planet, such as steamy tropical rainforests and the rain-drenched middle and higher latitudes of the northern hemisphere, have become both wetter and stormier... At the same time dry areas in continental interiors have become drier, causing deserts to spread... forest fires rage..."("Human") The only people who can honestly believe they have nothing to fear from global warming today are those who are rich enough and American enough to avoid dependence on the earth, or care about its people. While some city dwellers, some corporate deities and political entities may be able to address the earth as a factor in their bottom line, the people need to know that there is more to nature than that. Global warming, despite corporate doubts and debate, has proven itself to be deadly already, to the earth we live on, and to our continuance as a species. Even in the best-case scenario, it is going to change the way the ecosystems of the world work, and continue to be destructive for centuries to come. In the worst-case scenario, if humankind does not change, it is almost inevitable that we will have created the force that will destroy us. ...read more.
