Task 2. Вставь слова в предложения об экологических проблемах:

1. Factories and power stations that burn coal and gas emit millions of tons of carbon dioxide into the atmosphere every year.

2. Trees and forests reduce carbon dioxide and release oxygen.

3. When factory waste and car exhaust fumes pollute the air, they can eventually fall back to the land and water as acid rain.

4. If we continue to destroy natural habitats, we may completely wipe out many precious animal and plant species.

5. One of the best ways to protect our planet is to reduce our use of fossil fuels and switch to clean energy sources like solar power.
