Soil pollution refers to the contamination of soil with anomalous concentrations of toxic substances. It is a serious environmental concern since it harbours many health hazards.
Soil pollution jeopardises health and food security, all of which hamper the well-being of the world's 3.2 billion people.
This unnoticeable affliction appears when the presence of adulterants becomes so high that it harms land biodiversity and endangers health, particularly through food.
The use of chemicals, fungicides and fertilisers can contaminate land, just as natural and man-made chemical substances.
CAUSES AND TYPES OF SOIL POLLUTION
Corrosion, loss of organic carbon, compacting and acidification are the major causes of current soil pollution. Also, the FAO distinguishes between two types of soil pollution – localised and broad based.
Because the causes of a particular type of pollution are localised and easily linked, they are accounted for by those causes. These types of land contamination are frequently found around sewage treatment facilities, old factory locations, highways, and metropolitan areas.
Broad-scale pollution involves a variety of origins that are difficult to pinpoint and spans over large areas. The spread of adulterants through air-groundwater systems in cases like these has a major negative impact on both the environment and human health.
Among the most common causes of soil impurity are industry, mining, military activities, waste which includes technological waste — and wastewater operation, husbandry, stock breeding, the structure of civic and transport architectures.
CONSEQUENCES OF SOIL POLLUTION
The poisonous substances that are deposited on the earth's surface adversely affect our health and well-being and affect food, water and air quality.
The most important consequences of soil pollution according to IPBES and the FAO are:
Damage to health
Soil adulterants enter our body through the food chain, affecting our health. Also, the spread of antibiotics in the terrain increases the pathogens' resistance to these medicines.
Poorer crops
Soil pollution agents jeopardise world food security by reducing the quantum and quality of crops.
Climate change
Between 3.6 and 4.4 billion metric tons of carbon dioxide were released into the atmosphere through soil decline in the first ten years of the twenty-first century.
Water and air pollution
Soil declination affects the quality of air and water, particularly in developing countries.
Population Migration
Soil declination and climate change will have driven between 50 and 700 million people to emigrate by 2050.
Species extinction
Soil impurity is one of the main causes that could spark the sixth mass extinction event in history — the population of land invertebrates fell by 38 between 1970 and 2012.
Desertification
The number of occupants in the driest areas of the earth could be 45 of the world's population in 2050, while world swamp areas have dropped in size by 87 over the last three centuries.
Profitable impact
Global profitable losses caused by soil declination are anticipated to exceed 10 of the world's periodic Gross Domestic Product (GDP).
HOW TO REDUCE SOIL POLLUTION
Soil pollution is a complex problem that requires governments, institutions, communities and individuals to take common measures.
The following are just some of the effects we can do to ameliorate its health
Eat sustainable foodstuffs, duly reclaim batteries, produce manual compost and dispose of medicines in the places authorized for this purpose.
Encourage a further eco-friendly model for animal husbandry and stock breeding, among other profitable conditioning.
Ameliorate civic planning and transport planning and waste water treatment.
Ameliorate the operation of mining waste, restore the geography and conserve clod.
Involve original communities and indigenous peoples in the design, perpetration and assessment of sustainable land and soil operation.
To reduce land emigrations, reduce, recycle, and reduce.
It's essential to exercise reforestation and afforestation.
Organic diseases, an intertwined pest control system, can all be used by growers.
One of the most important ways to help minimize tip waste, cover natural coffers, save wildlife, reduce noise, reduce energy use, and slow global warming is to incorporate recycling habits into your everyday life.
Reforestation avoids river and lake silting by reducing corrosion and conserving the top layer of soil. It prevents the soil from sealing and cuts down on the quantum of rainwater that runs off.
When compared to petroleum-grounded plastics, biodegradable plastics produce significantly lower waste. As biodegradable plastics degrade, they decompose into nontoxic, inoffensive matters. Thirty twoof the greenhouse gases are released by petroleum - grounded plastics.
