A paragraph about low-carbon environmental protection, writing calligraphy works, about 96 words.

There is only one earth for human beings, and we will always depend on the ecosystem of this planet. We need the earth to provide food for animals and plants continuously, and we need an atmosphere thick enough to protect human beings from excessive temperature and ultraviolet rays. We need the earth to provide enough water and oxygen to sustain life. Without green, all this will become a rootless source, just like hair growing on leather. How can hair take root and sprout without skin?
