Animals in danger
There are more than thirty million species of animals in the world. Every year some of these species disappear and we never see them again. Animals disappeared before there were people and the decrease became rapid after there were people. Around Africa, it is more serious than any other continent because deserts are expanding every year. In addition to the problem of deserts, it is very hot so it is difficult to live not only for human beings but also for animals. What we can do is to cherish every thing we use. We destroy environment and animals are in danger. Lots of animals do not die if we live without wasting food, electricity, and it also include too much luxury. We made many useful things and our life became comfortable, but instead of the life, we destroyed the environment and killed many animals. To cherish environment is important, but I think to continue that is the most important and difficult.
