to save the environment

I think it is difficult to eat less beef, because people have eaten beef since a very long time ago. It is difficult to change the culture, so we should think how we raise cattle without destroy of rainforest. At the same time, we should save the environment with other ways. We can walk or use the train to go to school or work place. We can recycle plastic bottle. We can join the events to plant trees. There are many ways to save the environment except eating less beef. At the end, even if it is culture to eat beef, we mustn’t eat hamburger too much. It is bad for our health.
