Have you ever imaged that one day we will have to live in a completely polluted world. It would be such an unhealthy life that our human beings and animals may die out. It is a common knowledge that out environment is gradually becoming contaminated seriously and man is the main reason.

It leads to that animals that are innocent are also put up with the consequence we are making. Human beings are slowly ruining our life by raising various disasters that makes our future in danger.

For example, we can reduce the amount of garbage by recycling, reusing things or avoid throwing them into the environment; riding a bike or walking instead of riding a motorbike, driving a car is the best way for us to cut down on the quantity of exhaust fumes,... What is important is that we are together protecting our world. To conclude, I would like to alarm that our world is being seriously polluted and needs to be helped.
