They do pollination, which helps plants grow. Without bees, about 80 per cent of the plants would not grow, and we would have fewer fruits and vegetables. That’s why we must protect bees. Sadly, the number of bees is dropping. What can we do? First, we can plant more flowers that bees love. Second, we should avoid using pesticides in our gardens. Third, we can build bee houses to give them a safe place to live. If everyone helps a little, bees can survive and continue their amazing work. Protecting bees means protecting ourselves. 1 学科网（北京）股份有限公司 $
