We are often told that we should protect the nature and save the Earth, and that we should try our best to stop some animals or insects from disappearing. Animals or insects can’t live any more because the weather changes or the habitat isn’t the same as before.
        Bees are hard-working insects. They make honey from flowers. These years, some scientists find that bees are fewer and fewer. Perhaps, there won’t be any bees in the world one day. Scientists say that some vegetables may not be bought in the future without bees. Why are bees disappearing? One of the reasons is that the weather becomes warmer every year. Some scientists say bees can’t smell food or flowers because of air pollution. Then bees die. Some scientists have another opinion. Bees become fewer because farmers use too many chemicals. It is said that bees weren’t seen again in a city right after people there started to use a lot of chemicals. Although scientists aren’t sure of the main reason, it is believed that protecting the nature from becoming worse is important. If we want to see bees fly in the sky again, make honey for us, or help vegetables grow, we should take action to save bees.
