Unexpected future

In the past, we always miss the goodness of childhood. Parents and relatives always teach us to study hard. Listening to the teacher at school, going home to listen to my parents, I always feel that we are still children who will never grow up. Nowadays, the pressure of our study is getting bigger and bigger, and the time for rest and entertainment is getting less and less. I can hear many students complaining: many homework, stress, fast class, incomprehension, strict teacher... and so on, and so on. We are all dreaming children, we are all looking forward to the future, imagining what is going to happen in the next second.

The future is unpredictable and unforeseen. We never know what is going to happen next time, like a dream.

In the future, China's science and technology is very developed. Every household has a robotic nanny. Cooking rice, washing dishes, washing clothes, doing housework, etc., all do not need us to do it. At present, China's population has reached about 1.7 billion, the population on the earth has reached 7 billion, China's population accounts for about 24% of the world, and about 365,000 people are born every day. It reached 2 billion in 1930, 3 billion in 1960, 4 billion in 1974, 5 billion in 1987, and 6 billion in 1999. The population growth rate has been accelerating in the 20th century. The earth can withstand up to 15 billion people. If this number is exceeded, the earth's resources will be seriously deficient, and the end result will be war. Scientists have shown that it is very likely that the development of the Earth will be overloaded.

Scientists are looking for planets that can survive for humans. Scientists have discovered traces of water and life on Mars. Transforming Mars is the primary task of scientists. Almost all of the stars on Mars are carbon dioxide. It is well known that plants absorb carbon dioxide to release oxygen during the day and oxygen to release carbon dioxide at night. We only grow plants on Mars and artificially control it on Mars. Day and night, the plant always believes that it is always daytime, so that the energy source continuously releases oxygen, and one day, oxygen will spread over the atmosphere of Mars. What a wonderful idea! However, the actual operation is very difficult, but I believe that human beings will be able to live on Mars because I believe in China's strength.

Mars is waiting, we are here!
