A carbon footprint(碳足迹) is the total number of greenhouse gases(温室气体) that are produced by our actions. A person's carbon footprint in the United States is 16 tons every year, one of the highest in the world. To avoid a $2°C$ rise in the earth's temperatures, the carbon footprint per year needs to drop to under 2 tons by 2050. 1 So here are some simple steps we can take to help.
Look at what you're eating
Eating more vegetables and fruit and less meat is surely good for our environment. 2 Eating less meat can reduce your carbon footprint by up to 500 kilograms of $CO_2$ per year.
Save energy at home
Much of the home energy is powered by coal, oil and gas. Try to use less energy by washing your clothes with cold water. 3 For example, you can put in solar panels(太阳能板) to collect energy from the sun for your home.
Walk, bike or take public transport
The world's roadways are full of traffic, and most of them are polluting the air. Walking or riding a bike instead of driving will reduce greenhouse gases. 4 For longer trips, choosing public transport will be better.
Reduce, reuse and recycle
Buying things that are well made can go a long way to reducing the amount of waste one produces. 5 Of course, if you can't reuse something, you can also try to recycle it.

The Seine is a beautiful river which goes through France. However, the Seine has been seriously polluted. There are even laws that do not let people swim in the water. Raphael wanted to clean the river. He wanted people to swim in the Seine in the future.
Cleaning the river was a big job. Raphael fished rubbish out of the river. He had done it nearly every weekend for the past two years. He fished with his dad. They could catch a ton of rubbish in a single day.
Raphael learned about cleaning rivers from YouTube. In 2019, he found a video.
People were fishing metal objects out of rivers. They used ropes tied to magnets(磁铁). That Christmas, Raphael asked his parents for supplies. He wanted some ropes, a hook(鱼钩), and a powerful magnet. The magnet was very strong. It could attract metal objects weighing more than a ton.
When he began, fishing for metal was just a lazy weekend activity. But Raphael soon saw just how much rubbish there was at the bottom of the river. He wanted to do more. “It became like a full-time job,” he said.
Raphael won an award for his efforts. He received the Medal of Paris. Raphael was confident about his progress in the last two years. A section of the Seine was clearer than the rest of the river. That was where he first started fishing for metal.
