Global Warming

With the global warming temperatures are higher. This can cause disasters like hurricanes, draughts, floods. Pollution causes the green house effect. It is more difficult to live on this planet if there isn't clean air. the trees in the forest produce oxygen so we mustn't cut them down.

To reduce the global warming we can reduce paper and plastics, use public transport and use natural energies. If we do this, the factories work less and they pollute less.
