1. This theory answers all the questions, Scientists are still asking questions and try to explain why so many plants and animals became extinct. It's one of the oldest mysteries in the world, and it may never be solved. 2. In 1900 many zoos had passenger pigeons, On 14 September, 1908 the last wild passenger pigeon was caught near Detroit, Martha, the last living passenger pigeon in the world, died on 1 September, 1914. Her body is placed in a museum in Washington, D.G. 3. Many of them think that a change in climate caused it. But what could cause such a change in climate? Some scientists say that an asteroid lell on the earth 65 million years ago. A huge cloud of dust rose into the sky. There was no sunlight. Temperatures became very low, and without sunlight, plants died. The dinosaurs died from hunger and freezing, 4. In the 18th and 19th centuries there were millions of beautiful passenger pigeons in the United States and Canada, A visitor from Holland wrote, in 1625, that there were so many pigeons that the sky was dark with them and no sun was seen. Today, not a single passenger pigeon is alive, 5. Dinosaurs lived on the earth for over 140 million years. Then, suddenly, 65 million years ago, all the dinosaurs died, and most of the other animals and plants died along with them. Over 75 per cent of life on earth became extinct. For more than 150 years scientists have tried to find out why 6. The passenger pigeon was one of the largest and most beautiful members of the pigeon family. It was about forty-live em long, had narrow wings and a long graceful neck, Its tail was twenty em long and was silvery white. The head was dark blue and the neck was gold and green and purple надо озаглавить помагите
Environment - a set of components of the environment, natural and man-made natural objects and man-made objects. Components of the environment - land, minerals, soils, surface and ground water, air, flora, fauna and other organisms, as well as the ozone layer of the atmosphere and near-Earth space, providing a set of favorable conditions for the existence of life on Earth. Pollution - into the environment of matter and (or) energy, property, location or number of which have a negative impact on the environment. Contaminant - a substance or mixture of substances, the number and (or) concentrations exceed established for chemical substances, including radioactive and other substances and microorganisms standards and have a negative impact on the environment. Air pollution - a really serious problem. Air is composed of oxygen, nitrogen, water vapor, and, thanks to our civilization, of a variety of toxic particles. The more of these particles in the air is, the less room is left in the atmosphere for oxygen. The problem of air pollution is not limited to the space outside. The air inside our homes and offices can be as dangerous to your health. The main source of pollution - cigarette smoke, but it is not the only one. Toxins are allocated even when you just cook. Every time you scratch the Teflon non-stick coating is allocated enough toxins to kill a canary. Greenhouse effect, which we all have been associated with the phenomenon of global warming, caused by toxic gases. The main enemy of clear atmosphere - methane. It is released from the decomposition of sewage. Greatly affects our waterways. In every neighborhood, in every city there drain sewer, storm water from the highways and municipal enterprises directly into the river. Everything goes into the water, passing minor cleaning steps.
