О динозаврах Supporters of the first theory insist that for most of the Late Cretaceous, the conditions were very stable: tens of millions of years have passed without any significant changes were. Perhaps the animal life in the world at that time had become too "spetsializirovannnoy" too stable to adapt to these conditions. A small change in the environment, such as an increase in temperature, or cooling of the atmosphere could have detrimental effect on the population of dinosaurs. Climate change has led to the impoverishment of the vegetation and dinosaurs lost their usual food sources. Another theory suggests that the tectonic shifts continental land masses led to convergence with each other, causing the animals acquired the ability to migrate and carry with them into new geographies diseases for which endemic populations could be vulnerable.
На английском языке Перевод на русский язык Endangered Species Вымирающие животные Every year the number of endangered species steadily grows. It would be good to define what the community of endangered species is. It is a population of organisms which is at risk of becoming extinct. More than 40 percent of all organisms are likely to become extinct soon, which is unbelievable. Some of them are simply few in numbers, some are threatened by changing environment. In most cases animal extinction, as well as other natural calamities, is a result of human actions. Many habitats are being destroyed around the world. It seems that endangered wildlife is everywhere around us. To think only that these cute little polar bears at the zoo are gradually going to become extinct. Human activity has strong influence on the process of animal extinction. People chop down numerous forests, leaving certain species without shelter and their natural habitat. They also build newer and newer factories, which release chemical wastes into ocean water. As a result, thousands of sea animal die out. Moreover, people often overexploit animals, buying and selling their valuable parts, such as skin, teeth, fat, tusks. Domestic animals are also badly treated. If people continue treating our environment in such way, we will soon be trapped in ecological disaster. There are many reasons for rare species’ conservation. Firstly, they have aesthetic value. Secondly, they are useful from medical point of view. And, finally, the ecology of our planet literally depends on them. С каждым годом количество исчезающих видов неуклонно растет. Было бы хорошо, дать определение самому сообществу исчезающих видов. Это собрание организмов, которые находятся под угрозой вымирания. Более 40 процентов всех организмов подвержены скорому вымиранию, что просто невероятно. Некоторые из них просто малочисленны, некоторые находятся под угрозой изменения окружающей среды. В большинстве случаев исчезновение животных, как и другие природные бедствия, это результат человеческих действий. По всему миру разрушают их естественную среду обитания. Кажется, что угроза исчезновения диких животных окружает нас повсюду. Подумать только, что эти милые маленькие белые медведи, которые живут в зоопарке, постепенно вымирают. Деятельность человека оказывает сильное влияние на процесс вымирания животных. Люди вырубают многочисленные леса, оставляя некоторые виды без крова и их естественной среды обитания. Также, они все время строят новые заводы, которые выпускают химические отходы в воду океана. В результате этого, тысячи морских животных вымирают. Помимо этого, люди часто чрезмерно эксплуатируют животных, покупая и продавая их ценные части, например, кожу, зубы, жир, клыки. С домашними животными тоже неважно обращаются. Если люди будут продолжать, так относится к нашей окружающей среде, то в скором времени мы окажемся в ловушке экологического бедствия. Существует множество причин для сохранения редких видов. Во-первых, они имеют эстетическую ценность. Во-вторых, они полезны с медицинской точки зрения. И, наконец, экология нашей планеты буквально зависит на
