Lets Save Environment while we still can.

Just 1,000 years ago human beings were an insignificant species on this planet: only a quarter of a billion people, barely into the Iron Age, spread thinly across the earth and subject to nature's whims. Today that species has increased more than fifteen-fold and its power has increased to immense proportions. The human race has made the world produce more, has covered it with cities, is felling its forests and consuming its oil. From being at Nature's mercy we now have the power to determine our own futures. But this new power brings with it tremendous and unprecedented responsibilities. It is now up to us to shape our own future.

LIMITS TO GROWTH

…OIL If exponential increases in oil consumption continue the wells will be dry by 2025.
…URANIUM The costs of extracting the earth's diminishing uranium deposits will become almost prohibitive by 2050.
…TREES 5.6 million hectares of forest are being felled annually - an area the size of Sri Lanka.
…DESERTS 19 per cent of the earth's surface is threatened with desertification

…POLLUTION Between 1978 and 2000 the amount of carbon dioxide in the atmosphere will have increased by 15 per cent.

Conserving the earth's resources means an 'energy transition' from non-renewable to renewable sources. Whether or not we continue to devour the earth's resources depends on who controls them and the price tag we put on them.

Population

Population is thought to boom till 11 billion and then stabilize somewhere around that.

FEEDING THE ELEVEN BILLION
If current trends continue food production will keep pace with population growth. But feeding the world's hungry depends on better distribution of production, not just higher yields.

FOR RICHER, FOR POORER
 

The rich will get richer and the poor will get slightly richer too. But if the division of the world's wealth remains the same as today, when the world population stabilizes the Third World will have 90% of the world's people and only 20% of the world's wealth.

Keeping all this in mind...its time we think sustainability!!!

Sustainable development is not a destination, not a static condition of society. Sustainable development is how you make the trip. It centrally involves social ethics, goals, governance policies, and world views. Almost everyone using the term has a much narrower meaning in mind. They are thinking about what I call ‘eco efficiency’. It means reducing emissions, improving energy efficiency, recycling materials. These are all useful things to do, but they do not together give sustainability. They just give a little time for us to make the difficult cultural changes.
