Happy Planet Part 5

The earth is suffering from many unexpected natural disasters. In the face of these disasters, sixth-grade students Luo Xiaoyu and Liu Mei contacted the old naughty grandfather of Happy Planet through the computer. The old naughty grandfather and the three brothers and sisters of the Paifeng family brought the most advanced scientific monitoring equipment on the happy planet and set up a laboratory in cyberspace to make the children aware of the damage caused by humans to the earth and how to improve it. Fifteen years later, Luo Xiaoyu became an outstanding environmental scientist on the planet and devoted himself wholeheartedly to the protection and construction of the home we depend on for survival. Finally, the people on Earth and the people on Happy Planet established a good learning exchange, and everyone happily went to visit Happy Planet.
