Impressions after video I have watched (about environment polluting). (5-6 sentence)

Recently I had watched about our environment and was a little shocked. Most of people dirty everything around us: water, air, soil ... Despite nature pollution (plants, trees) we also kill animals, our smaller friends. But we need stop it. If people will keep together and do some good things, like plant flowers, create reserves, our planet will be in safe. We will live without diseases, breath fresh air. Our future in our hands.
