Hello, the humanity! I would like something to explain, to make a very important request. The fact that I was seriously wounded. My wounds depend on you, my dear people. Unfortunately, you cut down my forest, pollute my waters, the sea. Oceans. You destroy all living things around him, pollute the air, thus destroying my atmosphere. Very many years I tried to tell you this to warn you that you can hurt me very deeply. But for all this time you have not heard, did not want to hear and now I'm yelling at you that you, my dear people, stopped! Thought... all living things from such deep wounds sooner or later dies.. with respect to your Earth
Our home, our common home The land where we live! Just look around: Here the river, there is a green meadow. In dense forest not pass, Water in the desert will not find But somewhere the snow mountain, And somewhere hot and winter... Miracles we all can't be counted, One of them the name is - Forests and mountains, and sea, All called Earth!
The earth is in great danger. Day after day, hour after hour humanity is sliding into the abyss of nothingness, is increasing the threat of global ecological catastrophe. And the blame we the people. Humanity takes, but rather selects from nature every year tens of billions of tons of substances and materials for their needs. Do we realize that the storehouses of the Earth is not infinite, that we have no right to take and take it all: water, gas, coal, wood, oil, harvest from the fields? When are we going to pay her for it is not trash, cut down forests, dirty rivers, and love and help
People started strong as the gods, And the fate of the Earth in their hands. But darken terrible burns The globe on the sides. We had long ago mastered the planet, Widely sweeping new age. On Earth so white spots no Black will wipe Lee, Man?
Forest is the main wealth of our planet. And in the pursuit of comfort we cut down the forests. Forests are greatly reduced. When the forests covered vast area of the planet. Now they are left 1/3 part. The forest there is no substitute. Here disappears the noise of city streets.50% of the dust in the city settles on the trunks and leaves of trees. In the forest the air is 300 times less microbes than in the city.
Dying forests from fires. Through the fault of the person is up to 80% of forest fires.
Imagine that we spin the globe so quickly that all the colors merged into one. What color will this revolving globe? Of course, the blue, because two-thirds of the earth's surface is water.
What happens now: water suffocates from industrial wastewater and municipal enterprises. We fill the river, sea debris, oil, coal dust, ash, foam washing powders and other waste. The consumption of fresh water is such that humanity could exhaust its reserves already by the year two thousand one hundred
In the cities the air is very heavily polluting emissions of the transport and industrial enterprises
The problem of waste is recognized by scientists as one of the most important and difficult. Waste is everything that people vyvalivaet on the planet as a result of their activity. Plastic snow and mountains cans disfigured forests and roadsides.
the average car produces more than 0.5 kg of waste in the form of gas less than every 35 miles away. It is worth noting that only 50 years ago, the average car polluting approximately 25 times more. length 70 miles, consisting of houses, plastic machines and radioactive waste, which is slowly drifting into the Pacific ocean. Experts suggest that this mass reaches two years of Hawaii, and a year later it's going to the U.S. West coast. in Colorado (USA) there are special sensors that measure environmental pollution after each passing car. Typically, such sensors are built into the curbs. it's amazing, but at intermediate calculations revealed that the average house, which is home to a few people, emits more carbon dioxide than a new car. The most modest estimates showed that the carbon dioxide at least twice.
Я обнял глобус – шар земной. Один – над сушей и водой. В руках моих материки Мне тихо шепчут: «Береги». В зеленой краске лес и дол Мне говорят: «Будь с нами добр. Не растопчи нас и не жги. Зимой и летом береги». Журчит глубокая река, Свои, лаская берега. И слышу голос я реки: «Ты береги нас, береги». И птиц, и рыб я слышу всех: «Тебя мы просим, человек, Ты обещай нам и не лги, Как старший брат нас береги». :Я обнял глобус – шар земной, И что-то сделалось со мной. И вдруг шепнул я: « Не солгу, Тебя, родной мой, сберегу».
