The correct answers are:
- to decrease reliance on fossil fuels;
- to improve air quality;
- to reduce habitat destruction;
- to reduce health problems;
- to reduce pollution;
The renewable energy sources are considered as the future of the energy sources, and this is because they are renewable (so they are always there) and they are much more ecological.
The fossil fuels reserves are slowly but surely spending and there will come a time when they will end, so the focus has to be on their total replacement.
The renewable energy sources are very good for ecological reasons, they will contribute to improvement in the quality of the air through the reduction of pollution, and that will contribute to much reduced health problems in the human populations, as well as the animals and plants. Because these energy sources are much more ecological, they will contribute in big part in the protection and revitalization of the natural habitat, and it will be of great benefit for every living organism on the planet.
