How do humans destroy and protect the environment?

Indiscriminate deforestation and afforestation.

Exhaust pollution, electric vehicles.

A large number of people use disposable chopsticks every day, and they ignore the very important thing that is that disposable chopsticks are very wasteful of resources and can also cause damage to the environment. You know, millions of trees need to be cut down every year to make disposable chopsticks. On the other hand, the use of toothpicks is the same.

Both men and women use razors at some point, with men shaving and women removing leg hair and other hair. However, the regular use of disposable razors is very wasteful, because plastic cannot be used, and once it falls into nature, it will bring huge pollution. On the other hand, its production process also requires the use of a large amount of water.

The most comprehensive environmental study conducted by the United Nations Environment Programme (UNEP) has found that human degradation of the world's natural resources is rapidly outpacing the planet's ability to absorb damage, which means that the rate of degradation is accelerating on a global scale. Several factors contribute to this phenomenon. The first is overpopulation, with the global population rising exponentially since the eighteenth century.

Especially in developing or poor countries, over-growth populations are putting constant pressure on already scarce water and food resources. In the pursuit of economic development, these countries have had to do so at the expense of the environment.

On the other hand, rich countries are over-consuming resources, with the New York Times pointing out in 2008 that people in developed countries consume almost 32 times more resources such as oil and metals than developing countries. The Guardian reported in 2018 that humans alone accounted for the entire life of the species, but caused the extinction of 83% of wild mammals and plants. Taking animal husbandry as an example, data shows that only 4% of the world's mammals are wild at present, and the rest are farmed animals except humans.

The ratio of birds to wild birds is 7:3. The impact humans have on the natural world is enormous, and our dietary choices can have a huge impact on the habitats of other organisms.

Logging, destruction of vegetation, and destruction of biological habitats are not conducive to the absorption of greenhouse gases.

Wild animals are killed indiscriminately and biodiversity is destroyed.

1. The total amount of pollutant emissions is still quite large, far higher than the environmental self-purification capacity;

2. The task of industrial pollution control is still quite arduous;

3. Agricultural water quality and soil pollution in many areas are becoming increasingly prominent, and the harmful residues of agricultural products in some places are seriously exceeded, affecting human health and product exports;

4. Soil erosion and desertification are still intensifying in some areas.

Excerpt from the stack.

Human acts of destruction of the environment:

1. Shocking environmental pollution can be seen everywhere: the sky is dark, the air is dirty, sewage flows cross, and garbage besieges ......, even in the ice and snow of the Antarctic penguins, DDT and other pesticide residues have been found, Mount Everest is everywhere? The blue sky and clear water have become a childhood memory and unattainable dream for many people.

2. Excavation of river sand, excessive exploitation of groundwater, excessive mining and beneficiation, artificially destroying geological landforms, resulting in the deterioration of the natural environment.

3. Cutting down trees, destroying forests and wetlands, leading to abnormal climate change, reduced water resources, desertification of land, destruction of the ozone layer, extinction of some species, etc.

4. Killing and injuring animals, the imbalance of the natural biological chain, resulting in the deterioration of the ecological environment.

5. Human beings abuse antibiotics, abuse of various food additives, etc., resulting in the emergence of various stubborn diseases that endanger human beings, threatening human health, causing premature birth or malformation of the fetus, etc. Serious pollution incidents not only cause health problems, but also social problems. With the intensification of pollution and the improvement of people's environmental awareness, the disputes and conflicts among people caused by pollution are increasing year by year.

Protecting the environment makes it suitable for human life and work, and can make people's lives better. It can be carried out from the following aspects:

1. Prevent environmental pollution caused by production and living activities, including the prevention and control of pollution caused by the "three wastes" discharged from industrial production, the soot, sewage and garbage emitted by radioactive materials and urban life.

2. Prevent environmental damage caused by construction and development activities, including pollution and damage to the environment caused by the construction of large-scale water conservancy projects, airports and large-scale industrial projects, and the damage and impact on the environment caused by agricultural reclamation and lake reclamation activities, offshore oil fields, forests and the development of mineral resources.

3. Protect the natural environment with special value, including providing effective protection for rare species and their living environment, special natural development history relics, geological phenomena, landforms, etc.

4. Environmental pollution problems have occurred to varying degrees in the world, and the aspects with global impact include atmospheric environmental pollution, marine pollution, urban environmental problems, etc. With the globalization of the economy and the world, environmental pollution is also increasingly internationalized, and the transboundary transfer of hazardous wastes that has emerged in recent years is a prominent manifestation in this regard.

Human damage to the environment includes: human beings have caused great environmental damage by discharging waste water, waste gas, and fertilizers into the environment. It destroys the normal circumference of the atmosphere, causes global warming, causes water pollution, and extincts all kinds of wildlife.

Phenomenon: Due to the lack of anticipation of the negative impact of highly developed industry, the prevention is not profitable, which has led to three major global crises: resource shortage, environmental pollution, and ecological destruction.

Environmental pollution refers to the act of natural or man-made adding a substance to the environment that exceeds the self-purification ability of the environment and causes harm. (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 changing the composition or state of the environment due to human factors, and the decline of environmental quality, thereby disturbing and destroying the normal production and living conditions of the ecosystem and human beings.

1. Water depletion.

Water resources are water sources that are available or likely to be used, in sufficient quantity and of appropriate quality, to meet the specific needs of a place over a period of time.

2. Nuclear contamination.

Nuclear pollution mainly refers to the damage to the environment caused by the residues of nuclear material leakage, including the pollution caused by nuclear radiation and atomic fallout, as well as the secondary pollution caused by the pollution of these substances to the environment, such as the harm to humans and animals caused by the water contaminated by nuclear materials.

3. Marine pollution.

Marine pollution usually refers to the destruction of marine ecosystems by humans who have altered the original state of the ocean. Pollution caused by harmful substances entering the marine environment can damage biological resources, endanger human health, hinder fishing and other human activities at sea, and damage the quality of seawater and the environment.

4. Desertification of land.

Desertification in the narrow sense refers to the process of environmental change similar to desert landscape in areas that resemble desert landscapes in fragile ecosystems due to excessive economic activities by humans and the destruction of their balance. That is, to cut down trees indiscriminately, so that the balance of the land is destroyed and turned into sand!

5. Greenhouse effect.

The greenhouse effect, also known as the "flower house effect", is a common name for the atmospheric insulation effect. The atmosphere can make the solar short-wave radiation reach the ground, but a large number of long-wave thermal radiation released outward after the surface is heated is absorbed by the atmosphere, which increases the temperature of the surface and the lower atmosphere, because its effect is similar to the greenhouse for cultivating crops, so it is called the greenhouse effect.
