What impact will climate change bring?

Climate change will reduce crop production, affect ecological balance, affect the growth and reproduction of animals and plants, and affect human health.

Causes of climate change

To talk about the complex causes of climate change, first of all, human behavior patterns are hard to blame and have changed the natural greenhouse phenomenon. In the period after the discovery of oil, a large amount of oil and coal were burned, resulting in an increase in the concentration of carbon dioxide in the atmosphere. In addition, due to the large-scale reclamation of forest land and the expansion of industry and agriculture, the concentration of greenhouse gases is getting higher and higher.

Power generation, most of the electricity in the world is still generated by burning coal, oil or natural gas. In this process, carbon dioxide and nitrous oxide will be produced-these powerful greenhouse gases will cover the earth and absorb the heat of the sun.

With the use of transportation, transportation has become the main source of greenhouse gases, especially carbon dioxide emissions. Road vehicles emit the most emissions because their internal combustion engines burn petroleum products such as gasoline. However, emissions from ships and aircraft continue to increase. The carbon dioxide emitted by automobiles accounts for about a quarter of the global energy-related carbon emissions. The trend shows that the energy consumption of automobiles will increase greatly in the next few years.

The increase of population and the sharp increase of population are one of the main factors leading to global warming. Seriously threaten the balance of natural ecological environment. A large amount of carbon dioxide emitted by itself directly leads to the continuous increase of carbon dioxide content in the atmosphere.

Many forests have been cut down and forests have been reduced. Forests can absorb carbon dioxide, so destroying forests also limits nature's ability to prevent carbon dioxide from being released into the atmosphere.

Impact of climate change

Greenhouse effect, which is the most significant influence. With the increase of greenhouse gas concentration, the global surface temperature is also rising. Almost all the land is experiencing hotter weather.

Impact on food security, climate change has a huge impact on global food, mainly manifested in changes in planting structure and farming system, fluctuations in food output, and aggravation of agricultural disasters. Global arable land production has decreased.

The possibility of drought is increasing, and climate change is changing the availability of water resources, making water resources scarce in more areas. The desert is expanding and the land for growing food is decreasing. Nowadays, many people often face the threat of not getting enough water resources.

It seriously affects ecology and species, and climate change brings risks to the survival of terrestrial and marine species. These risks increase with the increase of temperature. Climate change has accelerated the rate of species extinction. Climate change leads to ocean acidification and affects marine ecology, such as coral death and fishery damage. Climate change leads to soil erosion, ecological degradation and species migration in China.

It affects the global human health, and climate change is the biggest health threat facing human beings. Climate change harms human health through air pollution, diseases, extreme weather events, forced displacement, mental health stress and increasing hunger and malnutrition in places where people cannot grow or find enough food. In some areas, the human mortality rate related to high temperature has increased. Climate change has led to the expansion of the distribution of many vectors and the increase of infectious hazards.

Forever, we only have one earth, which is the home of all of us. Not only the work of some people, but also the whole society, all walks of life and even each of us can actively cultivate energy-saving awareness, actively slow down and adapt to climate change, promote the development of the whole society to green and low carbon, and leave a clear water and blue sky for our future generations.
