Chapter Forty-Nine: Beginning the Course Learning about climate

Wang Zhan studied at the First University of Aojia National Capital, but the study was not popular, the popular one had been robbed by outstanding students in Auga, and he had chosen it for a long time, Wang Zhan chose geography, which was about climate. Pen? Interesting? Pavilion wWw. biquge。 info

Speaking of climate, Wang Zhan is not very adaptable, and it is different from Huaxia Kingdom. Wang Zhan struggled to adapt to the climate.

Here geography talks about climate, but also about environmental pollution. After hearing this, Wang Zhan had a lot of insights and found that this place was sometimes very similar to the present world.

Climate change has important implications for human and natural systems. Since ecosystems and human societies have adapted to today, it will be difficult for people to cope with these changes if they are too rapid for ecosystems and human societies to adapt. For many developing countries, this can have a very detrimental impact on basic human living standards (shelter, food, water, health). For all countries, the increased frequency of extreme weather and climate events will increase the risk of weather disasters. The impact of climate change on China's economy and society has both positive and negative impacts, and some of these changes are actually irreversible, so we should pay more attention to the negative impact. If left unattended, the economic losses caused by meteorological disasters will increase. There are two reasons for this, on the one hand, the increase in extreme weather events, and on the other hand, the increase in the overall economic volume of China, so the absolute value of economic losses has increased significantly.

The impact of climate change on agriculture is negative. The three major crops, namely rice, maize, and wheat, all have reduced yields except for winter wheat. The impact of climate change on water resources is also significant, with global warming accelerating the process of the water cycle and increasing spatial unevenness in precipitation. Climate change also has an impact on major projects.

Like the rest of the world, China's climate and environment have undergone tremendous changes. Climate warming far exceeds the general sense of climate and environmental problems, and has brought a very serious threat to China's economic and social development, and this threat will continue and intensify. The scientific and technological community should pay special attention to the issue of climate change, actively adopt adaptation and mitigation measures, and continuously improve the level and level of the climate system, ecology and environmental protection, which is an important part of the comprehensive implementation of the scientific concept of development and the establishment of a harmonious socialist society, and is the common aspiration of the government, the public and scientists.

In order to survive, humans have to adapt to a variety of different natural environments, and the most basic adaptation is to maintain a normal body temperature. Although body temperature can be done through physiological regulation, the regulation of physiological functions is limited. Clothing can put a person in an air layer where the temperature is higher than the ambient temperature and the change is less than the ambient temperature. Although clothing can not reduce the loss of heat in the human body, nor can it save heat, it can play a role in regulation, so that there is a layer of warm air around the body, not only that, clothing can also change the effect of temperature, humidity, airflow, and sunshine in the environment on the human body. In summer, as the outside temperature rises significantly, the evaporation of water from the surface of the bare skin increases dramatically, and wearing appropriate clothing can reduce the impact on the human body when meteorological elements change dramatically. When the human body is exposed to direct sunlight, clothing reduces the thermogenic effect of radiation. There are few summer clothes, and if they are worn properly, they can better reflect the beauty of the human body. However, in addition to paying more attention to aesthetics, summer clothing should also pay attention to not only sun protection, but also to dissipate heat from the body. Therefore, the color of summer clothing should be light, the material should be thin and loose, and synthetic fibers should not be used as clothing, because of its poor water absorption, and it is not resistant to high temperature and easy to humidity.

Wang Zhan found that environmental pollution is similar to the present world, but it has not yet developed into a highly developed information age.

Due to the lack of anticipation and prevention of the negative impact of highly developed industry, it has led to three major crises around the world: resource shortage, environmental pollution, and ecological destruction. Environmental pollution refers to the act of natural or man-made destruction, adding a certain substance to the environment and exceeding the self-purification ability of the environment. (Or due to human factors, the environment is polluted by harmful substances, so that the growth and reproduction of organisms and the normal life of human beings are adversely affected.) The phenomenon of disrupting and destroying the ecosystem and the normal production and living conditions of human beings due to changes in the composition or state of the environment due to human factors, thereby disturbing and destroying the normal production and living conditions of human beings.

Divided by environmental elements

Air pollution, soil pollution, water pollution.

By attribute

Overt pollution, hidden pollution.

By human activity

Industrial environmental pollution, urban environmental pollution, agricultural environmental pollution.

According to the nature and source of environmental pollution

Chemical pollution, biological pollution, physical pollution (noise pollution, radioactive pollution, electromagnetic wave pollution, etc.), solid waste pollution, liquid waste pollution, energy pollution.

Land pollution: Garbage cleaning has become an important problem in major cities, and many of the tens of millions of tons of garbage every day cannot be incinerated or corrupted, such as plastic, rubber, glass and other human enemies.

Marine pollution: mainly crude oil leaking from oil tankers and oil wells, pesticides and fertilizers used in farmland, sewage discharged from factories, and acidic solutions flowing from mines; They pollute most of the ocean's lakes and pollute not only marine life, but also birds and humans who can be poisoned by eating them.

Air pollution: refers to the concentration of pollutants in the air that reaches or exceeds the harmful level, resulting in the destruction of the ecosystem and the normal survival and development of human beings, and causing harm to people and organisms. This is the most direct and serious disease, mainly from carbon monoxide and hydrogen sulfide emitted from factories, automobiles, power plants, etc., and people are infected with respiratory or visual diseases due to exposure to these dirty air every day.

Water pollution: refers to the phenomenon that the chemical, physical, biological or radioactive pollution and other characteristics of the water body are changed due to the intervention of a certain substance, thereby affecting the effective use of water, endangering human health or damaging the ecological environment, and causing the deterioration of water quality.

Noise pollution refers to the phenomenon that the environmental noise generated exceeds the environmental noise emission standards stipulated by the state and interferes with the normal work, study and life of others.

Radiation contamination refers to the appearance of radioactive materials or rays that exceed national standards on the surface or inside of materials, human bodies, places, and environmental media caused by human activities.

In fact, Huaxia is already developing nuclear technology, but the Wako League is also taking measures to continue blind experiments, or steal the scientific and technological achievements of Huaxia, and the industrial development of the Wako League is already a perverted military industry, Wang Zhan feels that it is necessary to disintegrate the power of the Wako League.
