Of course, oh, there is a certain impact on the environment

Welding operators are exposed to fire, electric shock, burning, falls from heights and acute that may occur at any time.
Poisoning and other dangers, as well as the influence of arc light, welding fumes, toxic gases, high-frequency electromagnetic radiation, radiation, noise and thermal radiation and other harmful factors, are prone to industrial accidents and occupational hazards, and cause environmental pollution.
2. Welding fume: The welding fume particles are small, the fume is fragmented, the particle size is about 1 m, and the viscosity is large. Harmful gases: Produced under the high-temperature arc during welding, mainly ozone

Ecological protection is mainly the protection or restoration of the original nature world.
Environmental protection is usually handled by enterprises and other companies that may cause harm to the environment such as air and water through equipment and facilities, or even forcibly protected by law.

It's one thing to be abroad.
There is a difference in the country. Agree with fengxiangco.
Ecological protection is ecological restoration, and environmental protection is the treatment of three wastes.
-
Ecological protection is a science, and environmentalism is a concern. Also, if what you say is scientific, environmental protection can be achieved by various methods, and ecological protection is generally achieved by biological control methods.
-
Environmental protection is broadly defined.
Ecological protection should be part of environmental protection.
Ecological conservation focuses on the protection and restoration of natural systems.

Environmental issues are:
Plagiarism refers to the changes in environmental quality caused by human activities on the surrounding environment, as well as the impact of such changes on human production, life and health. The common "three wastes".
Ecological and environmental problems refer to the phenomenon that the structure and function of the ecosystem are seriously out of balance due to the destruction of the ecological balance, thus threatening the survival and development of human beings. Such as the invasion of alien species, land desertification, etc.
By definition, ecological problems are actually part of the environmental problem.
Generally speaking, environmental problems focus on the direct impact on the human living environment, while ecological problems focus on the impact on the ecosystem.
For example, industrial sewage entering rivers pollutes water quality, which is generally an environmental problem, but when it affects the habitat of a rare species, it evolves into an ecological problem.

1) Ecological environment refers to the whole composed of various ecosystems composed of biological communities and abiotic natural factors, which are mainly or completely formed by natural factors, and indirectly, potentially and in the long run have an impact on the survival and development of human beings. The destruction of the ecological environment will eventually lead to the deterioration of the human living environment. 2) The environment is divided into natural environment and social environment.
The natural environment is the foundation of the social environment, and the social environment is the development of the natural environment. The natural environment is the sum of various natural factors that surround people, such as atmosphere, water, plants, animals, soil, rock minerals, solar radiation, etc. These are the material basis on which human beings depend.
These factors are usually divided into five natural spheres: the atmosphere, hydrosphere, biosphere, pedosphere, and lithosphere. Social environment refers to the processing and transformation of natural materials to create a new environment by human beings through long-term conscious social activities on the basis of the natural environment. Human beings are products of nature, and human activities affect the natural environment.
3) The difference between the natural environment and the ecological environment The ecological environment and the natural environment are two concepts that are very similar in meaning, and sometimes people use them interchangeably, but strictly speaking, the ecological environment is not the same as the natural environment. The extension of the natural environment is relatively wide, and the whole of various natural factors can be said to be the natural environment, but only the whole system composed of certain ecological relations can be called the ecological environment. Although a whole composed of abiotic factors can be called a natural environment, it cannot be called an ecological environment.
In this sense, the ecological environment is only one type of natural environment, and the two have an inclusive relationship. The natural environment includes a certain ecological environment, biological environment and underground resource environment of human life.

Yes, for example, the environment has.
What social environment, human environment (culture, religion, etc.), ecological natural environment, etc., we usually say that the answer environment will be associated with the natural environment, the natural environment emphasizes a wider meaning than the ecological environment, not as usual we will say that man and nature live in harmony, but not that man and ecology live in harmony. Thank you, understand the limited hope to adopt!
Protect the environment, give priority to environmental impact assessment, and strictly control environmental damage.
You and I work together to build a home together.
Protect the ecological environment.
We live on this wonderful earth, and the earth has created us human beings, and has selflessly contributed to us and provided resources. And we humans torture it inhumanely, and its generosity is a waste of humanity. Therefore, in order to make the earth more beautiful and for us to be able to survive in a better environment, we must carefully protect the earth and protect the earth's ecological environment! >>>More

The increasing uncertainties and instability factors in the international environment of global ecological and environmental governance include: 1) the deep-seated contradictions between man and nature are becoming increasingly apparent, and 2) the game between major powers makes the global environment more complex.
