AN EARTH FOR NO ONE
No one will live happily on this earth. whatever our religious people say about the origin of species and creation of universe, this is an absolutely true, because so many creatures so far completely extinct and we are ready to make ourselves extinct. One the eve of the UN Conference on Environment and Development held at Rio de Janeiro in June 1992, the Union of Concerned Scientists published an open letter titled ,world Scientists’ warning to Humanity , which stated that “ human beings and the natural beings are on a collision course’’. The letter stated further, “if not checked, many of our current practices put at serious risk the future that we wish for human society and the plant and animal kingdoms, and may so alter the living world that it will be unable to sustain life in the manner that we know”. This warning was signed by over 1600 scientists from leading scientific academies in 70 countries. The list included 104 Nobel Laureates. Colborn, Dumanski and Myers (1996) in their book “Our stolen Future” and James Morgan (1999) in his book “The Last Generation” also provide a picture of the grim future that awaits the generations yet to be born, if we lose future time in restoring harmony between humankind and nature. It is not widely realized that the genes , species, ecosystems and traditional knowledge and wisdom that are being lost at an increasingly accelerated pace limit our options for adapting to local and global change, including potential changes in climate and sea level. The Hadley centre of the UK, Meteorological office has recently predicted that even if Governments cut green house emissions, sea levels may rise by at least 2 meters over the next few hundred years. If the global community can limit emissions up to 550ppm, which is twice the preindustrial levels ND 50% above today’s about 2 billion persons can be saved from water shortages, low crop yields and increased coastal flooding, especially in India and Africa(New Scientist, 30 October 1999). The Global Biodiversity published in 1995 by the United Nations Environment Programme (Cambridge University Press) estimates that about 13 to 14 million species may exist ou our planet.
Of this, less than 2 million species have so far been scientifically described. Our knowledge of soil microorganisms is still poor. Also, biosystematics as a scientific discipline is tending to attract very few scholars among the younger generation. Another important paradigm shift witnessed in recent decades is a change in the concept of “common heritage”. In the past the atmosphere, oceans and biodiversity used to be referred as the common heritage of humankind. However, recent global conventions have led to an idea that Biodiversity is now the sovereign property of the nation in whose political frontiers it occurs. We will face new problems, such as the following: First, increasing population leads to increased demand for food and reduced per capita availability of arable land and irrigation water. Second, improved purchasing power and increased urbanization lead to higher per capita food grain requirements. Third, marine fish production is tending to become stagnant and coastal aquaculture is facing environmental problems. Fourth, there is increasing demand to the ecological foundations of agriculture, such as land, water, forests, biodiversity and the atmosphere. The technological developments in the field of biotechnology, their environmental, health and social implications are yet to be fully realized. The impact of technology in every field of crop and animal husbandry, inland and marine fisheries and forestry has been profound. Therefore one must understand that the entire process of “Human Development” is a dangerous thing not only to the species but also to the entire humankind.
