Beat Air Pollution. Iman Shihabeldin (Sudan)
Pollution is one of the most dangerous global killers. We might not notice its According to the World Health Organization nearly 7 million premature deaths Nowadays air pollution has become a commonplace term that our ears are attuned The Industrial, Domestic and Natural Causes of Air Pollution : • Industry. Industrialization is very important for development and economic growth, • Transportation. Transportation has a big impact on the environment, as it is the biggest consumer of the world's petroleum. That creates nitrous oxides and other particulates that cause air pollution. Also, it causes emission of CO2,, the significant contributor to global warming. In 2013, transportation contributed more than half of the carbon monoxide and nitrogen oxides and a quarter of the hydrocarbons emitted in the air.
Some of the practices associated with agriculture have negative impacts on the environment. Transforming forests into farmland destroys habitats and releases carbon dioxide into the atmosphere. Also, it affects the natural ecosystems and biodiversity.
Asbestos, carbon monoxide, lead, mold, radon and volatile organic compounds (VOCs) are the most dangerous indoor air pollutants. Household pollution is very dangerous indeed, its level of danger depends on the concentration of the pollutants in the indoor environment. About 3.8 million people die of household pollution a year, says WHO.
Not all air pollution is caused by humans, here is a natural air pollutant. Fires can be deadly, destroying the wildlife and polluting the air with emissions harmful to human health and spreading CO2 . On the other hand,
CFC is an organic compound that contains Carbon, Chlorine and Fluorine, produced as a volatile derivative of Methane and Ethane. CFCs have no natural source. The most common emitter of CFCs are refrigerants. CFCs can ruin the ozone layer, this reduces the protection it offers from the sun's harmful UV rays.
As mentioned, air pollution is becoming more dangerous on daily basis. The fight This is a real global hazard! Air pollution has negative effects on literally • Humans 9/10 people breathe polluted air. In 2012, air pollution caused premature deaths on an average of 1 year in Europe. Most of the affected people are people of middle/low income. Air pollution causes serious diseases that lead to death. • Animals Animals depend on oxygen from the air. When the air is contaminated, harmful gases and toxic substances are inhaled. Which may cost the animal its life. • Crops Crops can be injured when exposed to high levels of air pollutants. Which reduces its growth and food production , causes premature death and economic loss. Industrial and commercial activity damages the crops and farmland on both short and long terms. The biggest air pollutants affecting plants are ammonia, nitrogen dioxide, sulfer dioxide and ozone. • Water Pollutants dissolve in water, causing direct water pollution. Polluted water vapors and condenses with the clouds causing acid rain. This damages the underground water and has short term damage on ocean water. • Forests Researches show that air pollution has a big impact on forests and ecosystems. It damages the leaves, limits nutrients and acid rain weakens the trees. • Ozone Layer When high energy electromagnetic waves reach the earth's surface, both humans and animals are exposed to several harmful effects due to the ozone layer depletion. Direct expose to UV rays causes skin cancer and other skin diseases.
Emissions of pollutants into the air result in changes of climate. Climate change occurs when carbon dioxide, pollutants and greenhouse gases collect in the atmosphere and absorb sunlight and radiations that have bounced off the earth’s surface. Thus, the relation between air pollution and climate change is direct. The UN intergovernmental panel on climate change warned coal-fired electricity must end by 2050. If not, we may see a major climate crisis in just 20 years. The consequences of air pollution are deadly, but there are things that can be done. • Raising awareness. • Planting trees.
• Limit driving by carpooling.
