①AI is used to help solve problems in many fields now. Here’s how it helps save energy, protect animals, and reduce pollution.

②In many office buildings, people sometimes forget to turn off the lights or the air conditioners (空调). As a result, a lot of electricity is wasted. Thanks to AI, the problem can be solved. It learns what the temperature is and how many people are inside the buildings. Then it makes thousands of small changes to save electricity every day. No single change is big, but all of them together can make a big difference.

③Another problem is about hunting wild animals. You can’t imagine how many kinds of wild animals around the world are in danger now. Luckily, AI can collect all the data (数据) to learn from the past hunting events. Then it can guess where the hunters will go next. It was once used in a certain area, and the number of hunting events dropped from 19 a month to zero.

④How can AI help reduce pollution? To clean up plastic waste from the ocean, you first need to know where it is. However, it’s difficult because the ocean is too wide. But with satellites (人造卫星), AI can quickly make a map to show where the plastic is. This helps clean up the ocean much more efficiently, because the ships can be sent to the right places to collect the plastic waste quickly.

⑤However, none of these benefits come for free. Training AI also uses a lot of energy. So we should make wise choices.
