《2024年仁爱英语同步练习册九年级全一册仁爱版》

People use cows to drive their vehicles, which is a traditional Indian sight. However, India’s cows are not very lovely.
In India, there are nearly 485 million animals, and half of them are cows. Cows produce a great number of CH₄—a greenhouse gas, and it causes 20 times more heat than CO₂. But can Indians kill cows to solve the problem? Certainly not. As the world’s largest producer of milk, India will still have to increase the dairy production(乳制品) to keep up with its growing population. So cows play an important role in people’s life.
Scientists are designing diets to help cows eat better. In this way, they will make unpleasant gas less. But most Indian farmers can only afford poor food for their cows. So many farmers add herbs(草药) to the food now. The herbs are cheap and they can produce less CH₄. And the cows don’t seem to mind the taste.
Besides, quite a few projects are going on. One of them is biogas production — cows’ waste is used as energy in kitchens and vehicles. It helps stop global warming(全球变暖).
