The Copenhagen Conference on climate change ended last Friday with a political compromise. But I wish political leaders, economic circles and members of other environmental conferences would begin to view Earth's environmental problems from their very foundation rather than from narrow-minded calculations.

Political and economic leaders may think that our environmental efforts should be compatible with economic growth, but economic growth won't be attainable without the proper environmental conditions for human survival. Moreover, economic growth will be meaningless if Earth's environment faces unrecoverable disaster.

Our economic activities cannot be separated from the reality of our being living things on Earth. We cannot explain climatic changes of Earth's past 4.5 billion years, nor can we predict future changes in Earth's climate exactly. So, we should pursue scientific studies and pay heed to the most up-to-date expert advice. Every one of us is responsible for our survival.
