Pollution is rubbish and toxins in our environment. People pollute nature, lakes and forests, air and soil. Every day in big cities people produce a huge amount of rubbish. This is gases from cars that pollute the atmosphere, and toxic waste that is thrown into the ocean. Pollution can lead to the fact that people will not have enough food, clean water, fresh air. Inhaling dirty air people can get poisoned. We destroy trees, animals, world Ocean. But without this we can't exist. Polluting the nature, we make ourselves worse.
