The composition.

I don't agree with the idea. In my opinion, we have learnt to destroy the world with the pollution and more causes.

At first, we have to recycle every day of the week. We have to put some of rubbish in the different bins.
We have to recycle so as not polluted the world, because if we don't recycle, the world will be ill!
At second, we have to use the energy of the Sun, the energy of the water (rivers, lakes and sees) and the energy of the wind. However, we use energies like oil or coal, but we wouldn't use these energies if we didn't change the world.

Then we have to respect the water of our planet because if it disappears, a lot of living being will be wipe out!! We have to use the minimum litres of water.

In conclusion, I would say that we had to change more things of our life because we learn to respect the world. If we made more effort, the world will be a better place for everybody.
