If I were an inventor, I would do something good for everyone's life.
It is often reported in the news these days that there is a serious haze in some places. It brings hidden danger to people's health and traveling, global warming, the Arctic ice and snow began to melt a lot, at this rate, in another twenty years, the Arctic summer ice and snow will no longer exist. The water in the lake and Tianchi dried up. So far, because of the massive cutting down of trees, the desertification of land has become more and more serious, and it is said that every day, on average, a piece of land the size of a soccer field turns into a desert. A car on the road discharges an unpleasant odor, and chimneys in various large and small factories can be seen everywhere, and the smoke blackens the sky.
If I were an inventor, I would have to invent a machine that has an air purifier that filters out particles and microorganisms that are harmful to your health, a base that grows trees, and a large box at the top of the machine that is connected to the machine, which is loaded with hydrogen and floats in the air. In this way, it not only protects the environment, but also saves floor space. It's called the "Air Purifier".
I'm also going to invent a machine that can take a small amount of heat out of a region, compress it, put it in a strong tank, and send it around in container trucks for families to cook with and for power plants to generate electricity, so it won't make the world unbearably hot. It's called a "thermal cooker".
I want to invent another machine, it can be a street noise is greatly reduced, so that can let the square dance of the big moms feel at ease to dance, so that the library readers have a quiet environment to read books. Its name is "Bird and Flower".
In order to realize my dream, now I have to study hard and turn my dream into reality as soon as possible.
