What About The Earth?

Today in this post ,we go back to the Year 1992,when over 1500 of the world's scientists--including more than half of all living Nobel Prize winners --signed The World Scientist Warning to Humanity.This document reflects growing concerns about the state of the biosphere:
Author:Moti Nissani
Nissani Moti is an inter disciplinarian holding degrees in genetics,philosophy ,and with many publications in genetics ,ecology ,politics ,science education ,and language instructions.
His essay below provides a brief introduction to the twin problems of overpopulation and deforestation ,especially in Nepal's context.

Nissani further writes:Human beings and the natural world are on a collision course.Human activities inflict harsh and often irreversible damages on the environment and on critical resources .If not checked ,many of our current practices put at 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 we know.Fundamental changes are urgent if we are to avoid the collision our present course will bring about.
In an unusual joint statement of the same year,the Royal Society Of London and the U.S National Academy of Sciences concurred:
The future of our planet is in the balance ,sustainable development can be achieved,but only if irreversible degradation of the environment can be halted in the time .The next 30 yrs may be crucial.
The facts speak for themselves.The chances of contracting cancer,emphysema,or asthma,are far higher now than they were a century ago.Human sperm counts in many localities are worrisomely low.Many of us suffer from premature hearing loss traceable to excessive noise.
We work longer hours than our parents did and spent more time in getting to and from work.We are troubled by the effects of such things as lead and dioxin on our children's intelligence and health.We think twice nowadays,before plunging in hot summer days,into possibly contaminated rivers ,lakes or seas.We can no longer experiance true wilderness.We are uneasy about poisons in our food and drinks;in our homes and work place ;in our air,water,soil;in our brainsand livers,in our pets,domestic animals ,lawns,and farms.
We are surrounded by signs of global environmental decline.Worldwide,some species of frogs,salamanders,and penguins are declining.We have apparently learned nothing from the extinctionof the dodoand the great auk,of the wild of the most human-like minds we know of-those of apes and cetaceans -is in doubt.Entire fisheries are acting as f there are no such things as carrying capacity and future and future generation ;as if we have learned nothing from the environmental failures of earlier civilisations.We continue to produce plutoniumand other long-lived poisons,even though we know that nothing on earth can be safely sequestered for millennia.We continue to litter space.When we fight pollution,we typically try to partially clean things up after the fact ,insted of opting for the cheaper and healthier path of preventions of sizzling temperatures ,floods,tropical diseases and mass migrations will prove wrong.
It takes a great deal of study and reflection to undersatnd the nature ,causes ,consequences,and cures of just one of these environmental ills.No comprehensive coverage of any single ecological issue can be undertaken in this brief,introductory essay.Instead,I shall only limit myself to a few cursory remarks about two major interrelated challenges:overpopulation and deforestation .In doing so ,I hope to alert you to the seriousness of both and to the need for collective and personal actions.
