Summary
Good (morning/afternoon/evening) ladies and gentlemen. On this annual convention of Citizens for a Greener Planet, we all gather to understand and apply the sustainable development. On such occasions, we usually forget that what we are aiming at here are not facts and figures or data that are deteriorating our existence, our survival…

The 'decline and fall' of Easter Island and its alleged self-destruction has become the poster child of a new environmentalist historiography, a school of thought that goes hand-in-hand with predictions of environmental disaster. The researchers dispute that the claim that Easter Island's human inhabitants were responsible for their own demise. Jared Diamond shares an exceptional view point in Easter Island case. In his book1 he says that the people of Easter Island destroyed their forest, degraded the island's topsoil, wiped out their plants and drove their animals to extinction. Helping its readers conclude, that the collapse of the Easter Islands was a man-made end. However, comparing the similar situation to today's scenario, something similar is at our end. We may not know that we are suffering the heat due to the endurance in man, but when it gets killing, by then it would be too late. The self-inflicted environmental devastation in the Easter Island, caused its complex society collapsed, also descending into civil wars, cannibalism and self-destruction. Something much similar to today's 'commercial' wars with nothing but a global existence of man eating man.Diamond's theory of ecocide was an actual genocide terminated Rapa Nui's indigenous populace and its culture that became almost paradigmatic in environmental circles, a dark and gory secret hangs over the premise of Easter Island's self-destruction. Lipo thinks the story of Easter Island's civilization being responsible for its own demise might better reflect the psychological baggage of our own society than the archeological evidence.
Now, let's look up at another example which is the on-going deforestation of the Amazon rain forest. Between May 2000 and August 2005, Brazil lost more than 132,000 square kilometers of forest-an area larger than Greece-and since 1970, over 600,000 square kilometers (232,000 square miles) of the Amazon rainforest has been destroyed.2 NASA satellite data are giving scientists insight into how large-scale deforestation in the Amazon Basin in South America is affecting regional climate. Researchers found during the Amazon dry season last August, there was a distinct pattern of higher rainfall and warmer temperatures over deforested regions. Some 14,754 sq km (9,170 square miles) of jungle was lost in 2003, according to the Brazilian government.3 The dramatic impact on the Amazon is reflected through the fires and the climate change. The Amazon is losing its green and the drought there is making it become dangerously and highly inflammable. Researchers and Scientist believe that if fires continue in the Amazon, 50 per cent of the Amazon could simply dissipate into smoke. It was also recorded that the humidity levels in the Amazon were recorded highest in 2005.
We all want to develop. Develop from complexity to luxury. But it is not that all development needs to be non-eco friendly. In such immediate crisis where the world is crashing down to multi million pieces, it is sustainable development which comes most handy. Solar panels for household electricity, solar cookers to avoid over usage of LPG, filters for industrial chimneys and household, saving electricity, saving water, planting trees as much as possible, creating household dumps in your backyards to recycle organic waste, lesser usage of plastics etc are some ways to develop more constructively. No doubt it takes a lot of time and ...Download file to see next pagesRead More
