Answer 1

答案：
解析：

There are many reasons for animals dying out, but the most important one is the part that humans have played. First, many animals have been killed for food. Second, many of the places where animals used to live have been destroyed. Lands have been turned into fields. Forests have been cut. Much land has either been changed into agricultural land or used for building. Polluted rivers have also been a cause of death.
