The whole world should take joint actions to curb the worsening situation, for no single nation can do it alone.
Different countries, however, see the problem from different perspectives. Developed countries, having long accomplished the process of industrializing their economies and rectifying environmental pollution, tend to blame the current worsening climate on developing countries, who are desperately tapping resources for fast economic growth. The developing countries argue for their right to development.
Admittedly, developing countries should not follow the old path of developed countries, namely developing the economy first and then tackling pollution. But it is unrealistic, and unfair, to ask them to slow down, or even stop their development to reduce CO2 emissions and other forms of pollution.
Developing countries need to follow a new mode, namely growing the economy with the least possible threat of pollution to the air, water and land. This obviously calls for advanced technologies and more capital investment. Developed nations can help in this regard. They have both the ability and responsibility to do so.
It has to be pointed out that the global warming is largely the result of developed countries' industrialization during the past two centuries. They contributed 95 percent of the CO2 emissions during the 200 years before 1950 and 77 percent from 1950 to 2000. They should undertake their historical responsibility. What is more, their current per capita emission levels are still higher than that of developing countries.
