Conservation of biodiversity
We are living at a critical time and conservation of biological resources on earth should be a top priority job for mankind. The world's forests, freshwater and marine ecosystems are endangered due to pollution and other human interventions.
We probably have already lost 1 million species and several more million will be lost in the first few decades of 21st century. [Source: Living planet index 2004].
So, the industrially developed countries must take proper initiative to diminish green house gas emission; otherwise biodiversity as well as human life will be imperilled.
