WHAT SCIENTISTS SAY "....."
SCIENTISTS ARE WARNING US ABOUT THE DANGERS
THE WORLD RESOURCES ARE GETTING DEPLETED. THE SCIENTISTS ALL OVER THE WORLD ARE SHOWING GREAT CONCERN. WHAT IS OUR DUTY?
We must understand the problem and follow some principles. We must be wise in using the resources.

A WAKE UP CALL
Scientists say we are living beyond our means. Is it true? Perhaps it is! Isn’t it shocking to hear that we have already consumed two thirds of the world resources and still do not respond to the call of the environmentalists?
We have almost tried our hands on each and every resource of the world and became the cause of depletion. Our forests, our wetlands, our mangroves, our soil, our water and even air have been thoughtlessly polluted or damaged by human activities. Now a stage has reached where one species may be a hazard to millions on the planet. The planet’s ecosystem can no longer withstand this onslaught on its vast resources. This earth which is the only living planet is on the verge of loosing its life if these warnings are not heard to.
What activities of man led to such disastrous situation? Let’s analyse and see:
1.As population increased the huge demand for food, shelter, fresh water, fuel etc. has increased. Demand for food led to more and more land being used for agriculture. Around 24%of the total land is used for agriculture.
2.Excessive demand for fresh water led to more than 50%of the fresh water from lakes etc being used by man. This is many times more than what it was a few hundreds of years back.
3.It is found that around 35% of mangroves, 20% of worlds coral reefs lost and the remaining badly damaged since 1980.
4.Some of the world’s greatest rivers are facing the risk of drying up much before reaching the sea.
5.Deforestation is raising the pollution levels and increasing global warming.
6.Many birds, mammals and amphibians are at the risk of extinction in this century.
Though man living in this technological age seems to have forgotten the vast benefits of nature, we cannot take these warning signals lightly. We need to respond to the call and the warning signals. Let us therefore do our best to take care of all these world resources and save our future generations.

Human footprint too big for nature, WWF, October 24, 2006
1."Already resources are depleting, with the report showing that vertebrate species populations have declined by about one-third in the 33 years from 1970 to 2003. At the same time, humanity’s Ecological Footprint—the demand people place upon the natural world—has increased to the point where the Earth is unable to keep up in the struggle to regenerate.— Human footprint too big for nature, WWF, October 24, 2006

Climate Change and the World’s Coral Reefs, Greenpeace, 1999
2.“If climate change is not stopped, coral bleaching is set to steadily increase in frequency and intensity all over the world until it occurs annually by 2030—2070. This would devastate coral reefs globally to such an extent that they could be eliminated from most areas of the world by 2100. Current estimates suggest that reefs could take hundreds of years to recover. The loss of these fragile ecosystems would cost billions of dollars in lost revenue from tourism and fishing industries, as well as damage to coastal regions that are currently protected by the coral reefs that line most tropical coastlines.” — Climate Change and the World’s Coral Reefs, Greenpeace, 1999

Vandana Shiva, Stolen Harvest, (South End Press, 2000), p.1
3. It is true that cutting down forests or converting natural forests into monocultures of pine and eucalyptus for industrial raw material generates revenues and growth. But this growth is based on robbing the forest of its biodiversity and its capacity to conserve soil and water. This growth is based on robbing forest communities of their sources of food, fodder, fuel, fiber, medicine, and security from floods and drought. — Vandana Shiva, Stolen Harvest, (South End Press, 2000), p.1

Dr. Boris Worm, Losing species, Dalhousie University, November 3, 2006
4. Whether we looked at tide pools or studies over the entire world’s ocean, we saw the same picture emerging. In losing species we lose the productivity and stability of entire ecosystems. I was shocked and disturbed by how consistent these trends are—beyond anything we suspected. — Dr. Boris Worm, Losing species, Dalhousie University, November 3, 2006
