1) The houses in photo A are special because there're good for nature. The solar panels save electricity by using solar energy instead. I think it would be nice to live in a home like this one, due to the fact that you are helping ecology.
2) I recycle at home. You can recycle paper, plastic, tin cans, plastic bottles can be reused too.
3) I think that public transport is the most environmental, because instead of everyone traveling by car, they travel in one bus. This way, people save a lot of energy and oil.
4) Companies don't have to import other products from other countries, thus saving electricity and energy.
