We have the ability to bring about a great change in our social, national and international life. But we cannot change everything. For example, humans can neither change the sun's radiation nor the earth's orbit around the sun. Rather we can control the increase in the amount of greenhouse gases and its effect on the atmosphere. It is a matter of great sorrow that only during the last hundred years the carbon dioxide concentration has been raised alarmingly in the atmosphere and we humans can be held responsible for this. Carbon dioxide level is increasing mainly for the burning of fossil fuels. Since the end of the 19th century, industrial activities increased rapidly giving rise to many factories. These factories required energy, which was produced through the combustion of coal and other energy sources such as mineral oil and natural gas which were also burned to heat our houses, run cars and airplanes or to produce electricity. Nowadays, about 85 million barrels of crude oil are burned daily. Every time a fossil raw material is burned, it releases carbon dioxide into the air. Thus, we are generating more and more greenhouse gases worldwide.

It is true that most of the natural phenomena are beyond our control, yet we can (a) _____ some aspects like the greenhouse effect by our responsible activities. We are highly responsible for (b) ______radical climate change. Carbon dioxide is the main (c) _____ of climate change. Carbon dioxide is being (d) _____ in the atmosphere by the burning of fossil fuels. Moreover, mineral oil and natural gas are also used for various (e) ______.
