What are the root causes of environmental problems that arise and intensify5

Covet! Including you and me, all and so on should not be said.

the evolution of man; the appearance of man; If people don't have such great abilities, if their brains don't have such Taos, then there are no problems, and people don't know. And then the environment evolves naturally.

Hehe: In that case, we won't have to talk about it here.

The causes of environmental problems are many, including physical and geographical factors, as well as economic, humanistic and social factors.

Economic factors: At present, China's economy is in a period of transition from the traditional planned economy to a market economy, and it is also a period of rapid economic growth in China.

Humanistic and social factors: "Ecology as a science, from the day it was born, has always been indissoluble with human society's indissoluble bond, if the early ecology shows more natural attributes, then modern ecology, more strongly shows its social attributes. ”

Environmental problems: the most obvious is the cause of human society, China's environmental problems, from the current point of view, this aspect of the factors have a greater impact. China has a large population and great pressure on environmental resources, and environmental problems and population are closely related to each other.

Under the conditions of a certain stage of social development, a certain geographical environment and a certain level of productivity, population growth should have an appropriate proportion, population and environmental problems are a major challenge to the development of contemporary China, the huge population and rapid growth have triggered a series of social and economic problems, and have caused a huge impact on the environment.

Geographical problems: mainly environmental pollution, now through continuous treatment is constantly alleviating; In the relatively poor areas of the western region, the deterioration of the ecological environment caused by environmental damage is very serious, and environmental problems are increasingly presenting.

<>1. Natural changes, such as volcanic eruptions.

** Activities will produce a large amount of waste gas and waste residue;

2. Human activities, human activities are the main cause of natural changes. Due to the production and life of human beings, a large amount of waste water, waste gas, waste residue and various garbage are discharged into nature, polluting the atmosphere and water resources, causing environmental pollution and ecological damage.

Environmental issues. Generally refers to the phenomenon of environmental quality decline or ecological imbalance caused by nature or human activities acting on the environment around people, and such changes in turn have an adverse impact on human production and life. Humans are transforming the natural environment.

And in the process of creating a social environment, the natural environment is still with its inherent natural laws.

Changing. On the one hand, the social environment is conditioned by the natural environment, and it also moves according to its inherent laws. Human beings and the environment are constantly influencing and interacting with each other, resulting in environmental problems.

The causes of ecological and environmental problems can be divided into two categories: the damage to the natural environment caused by the irrational development and utilization of natural resources, that is, the ecological damage commonly referred to as the ecological damage problem, such as soil erosion, land degradation, and species disappearance caused by indiscriminate logging of forest and steep slope reclamation;

Pollution caused by the development of industry and agriculture and human life, that is, environmental pollution.

There are many direct causes of ecological and environmental problems, and here are some of the common ones:

1.Industrial pollution: Waste gas, waste water and waste residue produced by industrial activities have caused pollution to the environment.

2.Burning fossil fuels: Burning fossil fuels such as coal, oil, and gas will release a large amount of greenhouse gases, leading to climate warming and affecting the ecological balance.

3.Globalization trend: With the development and advancement of globalization, the negative impact of multinational corporations and international companies on the environment has gradually intensified.

4.Urbanization: The process of urbanization is accompanied by various problems of urban development, such as urban garbage, sewage treatment and other problems.

5.Overgrazing and deforestation: Inappropriate grazing and deforestation disrupt the ecological balance and lead to problems such as desertification and soil erosion.

6.Misuse of pesticides and fertilizers: The overuse of pesticides and fertilizers pollutes soil and water sources, negatively impacting the environment. <>

Ecological and environmental problems are caused or likely to cause ecosystem imbalance and ecological environment deterioration caused or may be caused by natural changes or human activities, as well as the adverse effects on the survival and development of human beings and the entire biological world. The emergence and solution of ecological and environmental problems are synchronized with the development of human society, and the early ecological and environmental problems are mainly limited to the reduction of local biological resources, especially the wild animal resources as food, caused by the increase of human settlement and population, and with the development of agricultural and animal husbandry production and the establishment of cities, the destruction of regional natural resources has been caused. Since entering the industrial society, human consumption of resources and waste emissions have increased dramatically, and the ecological environment has become increasingly severe.

Ecological and environmental problems can be divided into the following causes: the first environmental problem (native environmental problem) caused by the change of some factors in nature itself, which is called natural disaster; The secondary environmental problems (secondary environmental problems) caused by human production or living activities are commonly referred to as environmental pollution and environmental damage.

Causes of environmental pollution.

In general, environmental pollution can be human life.

It can also be the result of natural activity, or the result of a combination of these two types of activities. For example, volcanic eruptions emit a large amount of dust and sulfur dioxide and other harmful gases into the atmosphere, which also causes pollution of the atmospheric environment. But usually, environmental pollution is more caused by human activities, especially socio-economic activities.

We usually refer to this kind of environmental pollution that originates from human activities. The reason why human activities cause environmental pollution is that there is a fundamental difference between human beings and other living things: in addition to their own production, human beings also produce materials on a larger scale, which is not found in all other living things.

Due to this, the intensity of human activity is much greater than that of other living beings. For example, other organisms only take the amount of water they need to survive in an ecosystem, while humans use water many times more than other organisms, so much so that in some local ecosystems, all the water is insufficient. The source of the emission of a pollutant is called the source of pollution.

The various sources of pollution will be described in section IV.

Environmental pollution can be classified from different angles. According to the type of polluted environmental system or the dominant elements in it, it can be divided into air pollution, water pollution, soil pollution and so on; According to the social field where the pollution source is located, it can be divided into industrial pollution, agricultural pollution, traffic pollution, etc.; According to the form or nature of pollutants, they can be divided into exhaust gas pollution, wastewater pollution, solid waste pollution, noise pollution, radiation pollution, etc.
