Why do we need to protect the Earth? She is big, she is enough for everyone - some will say so. Yes, the answer is simple: without it, we can not live a day. It feeds us, waters, warms, breathes and protects from meteorites. Yes, the Earth is huge, but we have one. And as scientists say, only it is suitable for human life. No one knows if man can survive on any other planet for even a day.

Now there are billions of people divorced. Not only nature has to feed everyone, but everyone also wants a house, a car and a lot of things. Plants are built for this, mines are working, and oil is pumped from the bowels of the earth, although it is possible to use the energy of water, sun, and wind. Smoke and other emissions from production enter the atmosphere, the soil and water. Man consumes all the resources of the planet, and they are exhausted.

Another person wants to dispose of animals, as if he created them. He even sometimes kills them for fun, not for food.

Only now people remembered: animals and plants are dying out, and global warming threatens to drown all our civilization in the oceans.

Now everyone knows that you need to take care of the planet, that you need to take care of it. Only many people think: let the state do it. Or let others try.

But scientists say that the planet can be saved only by joint efforts. Taking care of her is the business of each person and the business of each day. It starts small. This is turn off the light when it is not needed. Turn on the tap to prevent the water from flowing. This is a solar battery on the roof of the house and a car with an electric motor. A tree planted in a city street. Wrap or bottle, bonfire thrown into the urn
