Pollution is the way of making land, water, air or different pieces of nature messy and not sheltered or reasonable to utilize.The whole world should know about the pollution and its effects on environment and human health.
All forms of technology have come negative effects on the environment, sometimes agriculture too. Agriculture also produce some hazardous by-products.
Causes and Effects of Pollution
Causes and Effects of Air pollution:
Air pollution refers to a physical, chemical or biological change in the atmospheric air. It is a result of harmful gasses, smoke, or dust that enters the atmosphere and hinders the survival of animals and plants as the air contains toxic substances.
Air is necessary for all living entities, has a physical property and a chemical composition. The quality of air changes by the addition of contaminated gases.
Air pollution is caused by primary and secondary sources. If process directly pollute the air like release of Sulphur dioxide from factories is primary pollution. Reaction and interaction between primary sources such as formation of smog is secondary pollution.
Greenhouse effect mainly caused by chlorofluorocarbon has led to the depletion of ozone layer. That layer protects the earth from ultraviolet rays. Release of Sulphur dioxide in the air forms acid rain.There are carcinogenic chemicals in the acid rain which are dangerous for humans as well as aquatic organisms.
A reaction between combustion petroleum derivative discharges and sunlight makes smog cloud, a yellowish or blackish fog called “ground level ozone.” Climate change additionally makes progressively allergenic air contamination, for example, damped condition results in mold and polled brought about by a more extended pollen season and expanded pollen generation.
Respiratory issues like asthma and lung cancer mainly caused by air pollution. If a person is exposed to high level of air contamination, he may have irritation of nose, throat and eyes. Increasing air pollution causes global warming, which in turns causes rise in temperature, warming oceans, storms, and rising sea level which destroys natural habitats of wild animals.
Plants as a rule show harm in a variety of ways, including noticeable indications of harm like necrosis, hindered plant development, or changing in shading including chlorosis (otherwise known as yellowing leaves), blushing, bronzing, mottling.
- Controlling Post-combustion.
- Improving Industrial emission standards.
- Improving road vehicles Emission standards.
- Control Dust.
- Solid waste Management.
- Switching to renewable power generation.
- Managing agricultural residues.
- Enforcement of bans on open burning.
- Livestock manure management.
- Preventing forest and peatland fires.
- Improve the use of Nitrogen fertilizers.
- Residential waste burning.
Causes and Effects of water pollution:
“Thousands have lived without love, not one without water.” British poet W. H. Auden once noted.
Water pollution results from oil spills, trash especially plastic, construction sites and factories waste and run-off from agricultural lands. Drinking polluted water causes digestive problems in humans. Contamination such as mercury in seafood and fish can cause serious health problems.
A half year after the 2010 BP oil slick, which influenced 16,000 miles of U.S. coastline, more than 8,000 animals were accounted for dead. Animals are also killed by solid waste disposed of in water. Under 1 percent of the world’s freshwater is really available to us.
80% of plastic in our seas is from land sources to reduce the amount of plastic entering our sea, we have to both decrease our utilization of plastic all inclusive, and to improve plastic waste management.
At the point when water contamination causes an algal blossom in a lake or marine condition, newly introduced nutrients enhances the development of plant and algae growth, which thus decreases oxygen levels in the water. This shortage of oxygen, known as eutrophication, chokes out plants and creatures and can make “no man’s lands,” where waters are basically without life.
- Using bio-fertilizer, Herbicides, and Pesticides.
- Minimizing Stormwater Runoff.
- Treatment of industrial and household Waste.
- Solar energy, wind turbines and hydro power are all pollution free and should be used.
Causes and Effects of soil pollution
Soil pollution is anything that contaminate soil and lowers the soil quality. It occurs when the pollutants reduce the quality of the soil and convert the soil inhabitable for microorganisms living in the soil. Human exercises are the essential cause of soil contamination and land degradation.
The soil is the habitat for many bacterial biodiversity and other macroscopic living organisms. Human exercises, for example, abuse of pesticides the soil will lose its fertility. Presence of large amount of chemicals will increase the alkalinity or causticity of soil in this way corrupting the soil quality.
This will cause soil erosion. This soil disintegration refers to soil contamination. Excessive use of inorganic nitrogen fertilizers leads to acidification of soil and contaminate the agricultural soil. Also known as agro-chemical pollution.
Animals who eat contaminated plants ingest these poisons and have medical issues. Know that contamination makes an assortment of harm the planet in general. Living, working or playing in the polluted soil can prompt respiratory illnesses, skin infections, and different maladies. Additionally, it can cause other medical issues.
- Using correct farming methods.
- Proper disposal method of household and industrial waste.
- Recycling of Waste before disposal.
- Use of organic fertilizers instead of chemical fertilizers and pesticides.
- Community education and awareness.
- Proper maintenance of sewage system.
