Leonardo da Vinci. It was recently found hanging in a dark corner of a school in
Ireland. The school thought it was a copy. Art experts were called to decide the

The United States of America is a very diverse country. Its nature, climate, population varies from the East Coast to the west, from the northern border to the southern.Climate is mostly temperate, but tropical in Hawaii and Florida, arctic in Alaska, semiarid in the Great Plains west of the Mississippi River, and arid in the southwest.Natural resources include coal, copper, lead, molybdenum, phosphates, uranium, bauxite, gold, iron, mercury, nickel, silver, tungsten, zinc, petroleum, natural gas, and timber.Natural hazards are a great deal of problems for the USA. Every year, they loose hundred millions of dollars, because of natural hazards. The USA is famous for hurricanes along the Atlantic and the Gulf of Mexico coasts and tornadoes in the Midwest and southeast; mud slides in California; forest fires in the west; flooding.Sometimes there are tsunamis, volcanoes and earthquakes happen. Earthquakes are very often in California.Talking about environment, one should add that air pollution results in acid rains in both the US and Canada. The US is the largest single emitter of carbon dioxide from the burning of fossil fuels.Water pollution from runoff of pesticides and fertilizers takes place here.Climate and Natural Resources.
Климат и природные ресурсы.
Соединенные Штаты — это страна контрастов. Природа, климат, население страны изменяются с восточного побережья на западное, с северной границы на южную.Климат на большей части умеренный, тропический на Гавайях и в штате Флорида, арктический на Аляске, полузасушливый на великих западных равнинах реки Миссисипи и полупустынный на юго-западе.Природные ресурсы включают: уголь, медь, свинец, молибден, фосфаты, уран, бокситы, золото, железо, ртуть, никель, серебро, вольфрам, цинк, нефть, природный газ и древесину.Природные катаклизмы представляют огромную проблему для США. Каждый год страна теряет сотни миллионов долларов из-за природных катаклизмов. США известны своими ураганами вдоль атлантического побережья и побережья Мексиканского залива, торнадо на среднем западе и юго-востоке, грязевыми оползнями в Калифорнии, лесными пожарами на западе, наводнениями.Иногда наблюдаются цунами, вулканы и землетрясения. Очень часты землетрясения в Калифорнии.Говоря об окружающей среде, необходимо добавить, что загрязнение воздуха выливается в кислотные дожди как в США, так и в Канаде. США — самый крупный «производитель» двуокиси углерода от сжигания ископаемого топлива.Имеет место и загрязнение воды из-за сброса пестицидов и удобрений.

All animals in the world are divided into domestic and exotic. Pets or pets usually live near people. These include dogs, cats, horses, roosters, lambs, etc. Exotic or wild animals live in forests, savannahs, jungles, deserts, mountains. It has recently become popular to have exotic animals as pets. People buy snakes, peacocks, tigers, poisonous spiders and put them in cages or aquariums. Was it safe for us?
  It is a good idea to learn more about them. In addition, in the forest or in the desert, many species are in danger. Our help saves them because they feel our care and affection.
  However, wild animals are very dangerous for humans. They can attack, bite or even kill. Owners do not know how they need special food. Animals must live in their natural habitat.
  To summarize, there are good arguments. I think it's best not to keep wild animals at home. They were born free and not adapted for life in captivity. I propose building many reserves to live in this spacious environment. I must not forget that we can do harm!
