"On Carbon Sources"

Between heaven and earth, the growth of all things depends on carbon. Carbon sources are the foundation of life and the source of biochemistry.

The way to seek carbon sources is to first follow plants and trees. The plants are lush, prosperous in spring and withered in autumn, and their branches, leaves and roots contain carbon. Decompose into mud, and carbon returns to the earth to nourish all things. Farmers in ancient times often accumulated firewood and fallen leaves, thinking that it would fertilize the soil. This is the way to use plants and trees as a carbon source.

Secondly, manure is also a good source of carbon. The manure of humans and animals is rich in carbon and various nutrients. Applied to the fields, the soil is fertile and the crops are lush. And the accumulation of manure, recycling, is also an ecological way.

Furthermore, in minerals, there are also carbon deposits. Coal is buried deep in the ground, and after years, it is rich in carbon. However, its mining and utilization have advantages and disadvantages. The advantages are in energy supply, and the disadvantages are in the damage of the environment. It is necessary to use it with caution, and it is necessary to think about long-term strategies.

To find the best carbon source, ecological balance and long-term use should be the key. Grass, manure, natural choices, recycling, no damage to the environment. If used properly, the earth will be constantly new, and all things will thrive. Although the carbon of minerals can be emergency, it should not be used up to fish. When new technologies are developed, their harm should be controlled, and their sustainability should be pursued.

Making good use of carbon sources is related to people's livelihood and ecology. All lords should think about it and do it, so as to protect the beauty of heaven and earth and the vitality of all things.
