Dergana H/ S (2as) The Second Term English Test Topic B
Read the text then answer the questions:
Findings from a new study released last week prove that global warming is caused by human activity, and not by natural environment factors. Researchers at Scripps Institute of Oceanography have found a clear evidence of human produced warning in the world’s oceans that is likely to impact water resources in regions around the globe.
Many world leaders have closed their ears to this fact so that they don’t have to limit their economic activity or introduce expensive pollution controls. This is one of the reasons America has not signed Kyoto Treaty of climate change. The US government prefers to believe global warming is a natural phenomenon, caused by volcanoes and solar energy.
Beyond that, many international organizations which look for a better future environment are uniting in order to stop this phenomenon, or at least limit and reduce its effects on Earth and on the future life of our children. They believe that we still have a chance to do this if we believe that we can change.
