"On the Source and Impact of Carbon Dioxide"

Between heaven and earth, the transportation and transformation of gas is related to the life of all things. Among them, carbon dioxide, in the state of nature and the traces of people, has its source, and its impact is far-reaching and cannot be ignored.

The source of carbon dioxide is first and foremost natural creation. Mountains, rivers, lakes and seas are all its breeding grounds. Volcanoes erupt, the hostile gas of the earth is vented, and carbon dioxide is ejected with hot magma, permeating the sky. In the forest, trees breathe, day and night alternate, and between tona, there is also carbon dioxide scattered in the forest. There are also rivers, lakes and marshes, where water interacts with the atmosphere, and the metabolism of organisms and the decomposition of sediment all cause carbon dioxide to escape from the water and merge into the sky.

As for man-made sources, it is particularly significant. First, industrial prosperity, factories, all kinds of stoves and furnaces, powered by fuel, coal, oil, natural gas, burning, will be buried deep underground carbon, into carbon dioxide, billowing into the sky. Second, the traffic is heavy, and cars and ships are running endlessly. Car exhaust and ship exhaust all contain this gas, which shuttles through the city and countryside, causing the amount of carbon dioxide in the air to increase. Third, the process of urban expansion, the rise of high-rise buildings, the prosperity of civil engineering, and cement production is also the way to release carbon dioxide.

The impact of carbon dioxide has advantages and disadvantages. For the better, it is the raw material for plant photosynthesis. The stomata between the leaves open and close, absorb carbon dioxide, and use the power of sunlight to synthesize organic matter, building the foundation of life for all things and maintaining the cycle of ecology. Without this gas, the vitality of plants will be difficult to continue, and the food chain will collapse.

However, its disadvantages should not be underestimated. Carbon dioxide has a greenhouse effect and is in the atmosphere, like a thick blanket. Excessive accumulation leads to global warming, glacier melting, sea level rising, and coastal areas are at risk of flooding. And the climate is abnormal, with torrential rains, floods, droughts and extreme heat, and frequent extreme weather, endangering life and disrupting human livelihoods. And changes in atmospheric composition may cause ecological imbalance, and species migration and extinction may occur from time to time.

In today's world, the source and impact of carbon dioxide are of great importance to the world. Everyone should think of good strategies to save energy, promote clean energy, slow down the growth rate of carbon dioxide, protect the harmony of nature, and ensure the peace of future generations.
