Our planet is our home and we should take care about it. In fact it is not so difficult and everybody can do something, if he/she knows the following facts: 1.<span>Plastic bottles are recycled into supermarket bags.2.Glass bottles are metled down and made into new glass products.3. A lot of trees are saved if people recycle their paper.4..Walking to school instead of going by car is good for the environment.
Unfortunatell ymany people don't care about our planet. We know about the effect of the greenhouse gases and climate changes. So we should be more responsible about it. </span>
