Natural air pollution with different pollutants, such as fumes and chemicals. Both indoor and outdoor air pollution is a major environmental health problem affecting everyone, both in developed and developing countries. The majority of the world's population will be subject to a degradation in air quality by 2050 if man-made emissions continue as usual. In this “business as usual” scenario, the average global citizen 40 years from now will experience air pollution similar to that of today's average East Asian citizen.
The presence of environmental pollution raises the question of pollution control. Great efforts are made to limit the release of harmful substances to the environment by controlling air pollution, treating wastewater, managing solid waste, managing hazardous waste and recycling. Unfortunately, attempts to control pollution are often outweighed by the magnitude of the problem, especially in less developed countries. Harmful levels of air pollution are common in many large cities, where particulates and gases from transportation, heating and manufacturing accumulate and remain.
The problem of plastic pollution on land and in the oceans has only grown as the use of single-use plastics has flourished around the world. In addition, greenhouse gas emissions, such as methane and carbon dioxide, continue to drive global warming and pose a major threat to biodiversity and public health. Air pollution mainly affects those who live in large urban areas, where road emissions contribute the most to the degradation of air quality. There is also the danger of industrial accidents, in which the spread of a toxic fog can be deadly to populations in surrounding areas.
The dispersion of pollutants is determined by many parameters, including atmospheric stability and wind (. These five megatrends represent major global threats to planet Earth's problems that must be resolved if the world is to remain a favorable habitat for humans and other species. DW analyzes the causes and possible solutions. The good news is that clean energy is abundant, you just have to harvest it.
Many say that a 100 percent renewable energy future is feasible with existing technology now. Today, about 30 percent of the planet's land surface is covered by forests, which is about half that before agriculture began, about 11,000 years ago. About 7.3 million hectares (18 million acres) of forest are destroyed each year, mainly in the tropics. Tropical forests used to cover about 15 percent of the planet's land area; now they've shrunk to 6 or 7 percent.
Much of this rest has been degraded by logging or burning. Anthropogenic air pollution is one of the greatest public health hazards worldwide, causing about 9 million deaths a year (. In short, a global prevention policy must be designed to combat anthropogenic air pollution as a complement to the correct management of adverse health effects associated with air pollution. Beginning in 1000 AD, the use of coal as a fuel caused significant air pollution, and the conversion of coal to coke for iron smelting starting in the 17th century exacerbated the problem.
At this point, international cooperation in terms of research, development, administration, policy, monitoring and policy is vital for effective pollution control. In addition, air pollution appears to have several harmful health effects in the early stages of human life, such as respiratory, cardiovascular, mental and perinatal disorders (, which cause infant mortality or chronic diseases in adulthood). Short-term exposure to air pollutants is closely related to COPD (chronic obstructive pulmonary disease), cough, shortness of breath, wheezing, asthma, respiratory diseases, and high hospitalization rates (a measure of morbidity). Excessive noise pollution, from city streets to commercial ocean maritime traffic, can have harmful effects on humans, plants, animals, trees and marine life that are constantly exposed to it.
Pollution occurs in both urban and rural areas of India due to rapid industrialization, urbanization and the increase in the use of motorcycle transport. In addition, extremely high levels of pollution are reported in Mexico City and Rio de Janeiro, followed by Milan, Ankara, Melbourne, Tokyo and Moscow (1.Unfortunately, anthropogenic activities have destroyed this protective effect of temperature by producing large amounts of greenhouse gases, and global warming is increasing, with harmful effects on human health, animals, forests, wildlife, agriculture and the aquatic environment. These problems can be aggravated by prolonged and prolonged exposure to contaminants, which are harmful to the neurological, reproductive and respiratory systems and cause cancer and, in rare cases, even death. Undoubtedly, global environmental pollution is considered an international public health problem with multiple facets.
Modern society is also concerned with specific types of pollutants, such as noise pollution, light pollution and plastic pollution. Lead poisoning is a threat to public health because of its harmful effects on humans, animals and the environment, especially in developing countries. Adverse environmental effects, such as soil acidification and acid rain, appear to be associated with sulfur dioxide emissions (8). .
