Most organisms inhale oxygen and exhale carbon dioxide; most plants inhale carbon dioxide and release oxygen. When breathing one breath, the dynamic balance of oxygen and carbon dioxide in the atmosphere is maintained, and the life can be developed for a long time. It is the objective law of nature to eliminate the complementary sky track. If the amount of carbon dioxide in the atmosphere increases more than it is consumed, the "breathing" of the atmosphere becomes unbalanced, with the consequence of global warming.
Before the industrial revolution, the carbon content in the atmosphere was kept in a dynamic equilibrium of "growth while consumption". Most of the carbon dioxide released by the biological activity is absorbed by the sea and lake and dissolved in the water, a small part of the carbon dioxide is consumed as the nutrient for plant photosynthesis, and the carbon dioxide contained in the atmosphere is stably maintained at a trace level of 0.03%.
