How I Help to Protect Our Environment

We rarely think about what kind of world our future generations will live in. Meanwhile, each of us is able to contribute to protection of nature.

I have been thinking about the ways I can help to save nature. First of all, my parents and I try to walk more or ride our bicycles. Each time we keep away from using our car, we reduce air pollution and consume less oil. We also remember to switch off lights and avoid using disposable cups and plates, as well as plastic shopping bags. I always go shopping with a reusable canvas bag. Besides, we buy recyclable paper products to protect forests. I collect used papers, old newspapers, magazines, bottles and any other things that can be recycled. Another great way to protect our nature is to take part in river cleanup events in your city and collect litter that could destroy the natural homesites of birds and fish.  I also remember not to waste water.

These may seem small and simple things, but I believe they help to protect our environment .

These substances (number and variety of which is constantly growing) after their use are not available in the natural cycle. Waste production activities increasingly pollute the lithosphere, hydrosphere and atmosphere of the Earth. Adaptation mechanisms of the biosphere can not cope with the increasing amount of neutralization of harmful substances its normal functioning, and natural systems begin razrushatsya.1) Pollution litosfery.Pochvenny cover the Earth is an essential component of the biosphere.
