Composition "A Day on Mars"

Ten years later, I became a famous scientist to save the earth. That's because my colleagues and I have worked out how to survive on Mars.

You must think it's strange. Didn't scientists say that there is no oxygen and no water on Mars? That's because I invented a medicine that can change carbon dioxide into oxygen. As long as you take a sip, the surrounding carbon dioxide will become oxygen, so we don't have to worry about carbon dioxide anymore. I didn't buy melons in Wang Po-I was bragging! Speaking of water, several colleagues and I have come up with a "clever plan", that is, through the "sewage into water purifier" we invented, the sewage on the earth will be turned into clean water, but how can we drink enough just by relying on a little sewage on the earth? So, after hard thinking and hands-on experiments with my comrades, we finally invented a machine called "sand-mud mixer". Putting the desert on the earth into an oversized blender can change 1 g of sand into 1 1,000 g of water. So we don't have to worry about water.

There will be no exhaust gas from vehicles and factories on Mars, because all vehicles and factories were "vacuum-packed" at that time, and there would be no gas harmful to people, but gas beneficial to people. Mars gives off a fragrance every day, which can make people friendly, kind and honest, and there will be no thieves, liars and fakes in the world. . . . . . We live in harmony, just like a family. I also invented a "youth element" to make my parents young.

People living on Mars are happier than people living on Earth!
