Copenhagen is discussing climate change problems of green house gases. Nobody seems to care for the real problem of climate change being casued by unplanned growth of population which has neither to eat nor to feed nor keep themselves clean and keep environment clean. Slums are growing in several parts of the world with world population growing uncontrolled resulting in population pollution. Such nations who are not able to control their population should pay population tax to the world climate or UN. Its the slum populations which are destroying the climate of the world, uprooting the trees, destroying the forests and selling the woods and trees for greed of money. Most of the Forest agencies play a role in selling the forest products in legal and more goes in illegal manner. Some where one feels that those who are responsible for protection of forests  are mainly responsible for its destruction. Most of the developing countries dont have democracies in true sense and which have it are trying to play some active role in climate protection. India is one such country playing active role in climate protection but if population growth is uncontrolled in India and other countries of Africa or South east asia it will not be climate change due to gas emissions but the climate change due to excessive population and it needs to be discussed and controlled irrespective of caste religion or region if world has to survive.
Its climage change vs population change which causes threat to global earth. Plant a tree to save it rather than travel to Copenhagen to pollute the world more.
