Read the following text and fill in each gap with a suitable word based on the information of the text: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.

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.
