Nature is all around us. We see it every day. It is a sunset, sunrise, birds singing, the flowers bloom, the wind, etc. These signs are an integral part of our lives. On the one hand we cherish these natural benefits, on the other hand, we not fully appreciate their importance. Thus, our future generations may be deprived of these beauties. They can be reached in less natural wonders, because the world gradually destroys forests and destroys some species. All this is due to the industrial revolution and growing number of chemical plants. Humans are the only species on the planet, deliberately manipulating the environment. Unfortunately, we have bad leaders in the hierarchy, if you can't raise the level of ecology. People are too selfish to notice the damage they cause to the environment. For millennia they lived in harmony with nature prior to the introduction of civilization. They could have unlimited access to natural wealth, and today we have to save on all resources. Pollution is another threat to the nature. Many cities today are mired in noise and atmospheric pollution that comes from cars and factories. That's why some people try to live in the countryside, where the air is much cleaner and fresher. Global industry emits about 1000 million tons of dust and harmful substances into the atmosphere. As a result, many rare species of animals and plants are dying, lakes are drying up, forests are disappearing. Obviously, our precious nature at risk. And if people do not take serious measures to rescue her, then our planet will soon become lethargic.
