Almost all of the places of human dwelling and community activities such as homes, hospitals, schools, offices etc., tend to generate a lot of waste that is non-biodegradable. The removal of plant cover not only eliminates wildlife habitats and food for wildlife, but it also degrades the soil by leaving it barren and without the roots of plants to hold it in place, vulnerable to erosion. blow off or get washed into nearby rivers and streams, leading to the water levels rising and flooding during rains. It is estimated that eighty percent of land animals and plants live in forests. The liquid that leaks from landfills is known as leachate, often a. highly toxic liquid containing many chemicals resistant to ordinary wastewater treatment. Leave a comment. The contamination destroys the healthy organisms responsible for generating new vegetative growth. UPES PG Apply Now. It is not just direct pollution of toxic chemicals that can cause these problems. Some of main causes of soil pollution include deforestation and consequent erosion, agriculture, industry, mining, landfills and illegal dumping of waste as well as urbanization and construction [8]. Early investment in reclamation and ecorestoration practices will definitely help the company toward steady growth, to maintain healthy environment and free from statutory noncompliances (Table 20.5). This means that flooding is worsened as the land no longer has the ability to absorb excess rainfall [13]. Land pollution can be caused by several different factors, many of them related to human behavior. For humans to cause species to become extinct and to destroy the biological diversity of God’s creation, for humans to degrade the integrity of the earth by causing changes in its climate, by stripping the earth of its natural forests, or destroying its wetlands, for humans to contaminate the earth’s waters, its land, its air and its life with poisonous substances, these are sins. When it rains, a soil without plants to hold it in place will erode and the chemicals it contains on its surface and within the soil itself will runoff and pollute rivers and streams the water empties into, or bays and oceans, either directly or via tributaries. contaminating and finally completely destroying the soil composition. And finally, but far from the least, the base-camp of all the trash moving around the planet – Landfills. Deforestation carried out to create drylands is one of the major concerns. The major causes of land pollution are construction, domestic waste , industrial waste and agriculture. However, a lot of matter is left behind which is highly radioactive and contains many deadly chemicals. Forest are cut down because people want more settlement space and also for farming purposes. Conversely, while not documented, no one would dispute that the effect of seeing barren or polluted land is depressing. A recent study of the effects on the soil of dumping cassava showed many deleterious effects to the previously arable land. A dead zone at the mouth of the Mississippi River from fertilizer runoff primarily from corn fields along its banks, covers more than 7700 square miles (20,000 sq km) in the Gulf of Mexico during the summer months. Effects of land Pollution. The land is said to be polluted when the soil’s original natural composition is disturbed, due to the addition of foreign elements, to such an extent that it can no longer sustain the ecosystem that depended on it. A huge chunk of this pile of waste, which is not recyclable, get shipped off to a landfill somewhere, where it will sit for decades, and leak out toxic chemicals, paints, oils, metals etc. Such a polluted land, although may increase the production for a short while, in the long run, the productivity goes down. Today, almost all soil has at least small amounts of PCB [6]. Industrial waste is perhaps the motherload of all the pollutants afflicting the planet. You have probably seen garbage on the streets that are not cleaned very often. Prior to being banned in 1977 due to its adverse effects on humans and wildlife and long-term persistence in the environment, PCBs or polychlorinated biphenyls were widely used in industrial coatings and insulation materials for transformers as well as hydraulic fluids, fluorescent lights and various consumer goods. Various Causes of Land Pollution Land pollution is the destruction or decline in quality of the Earth’s land surfaces in term of use, landscape and ability to support life forms. These non-biodegradable waste can take hundreds to millions of years to decompose completely. This applies too to regulations governing mining and industrial waste and disposal of solid and hazardous waste. Read more about us. We can make sure that our personal litter is disposed of properly. The causes of land pollution can have drastic consequences, especially when looking at the survival of animals, humans, the quality of the soil and even the water. The cause is the accumulation of solid and liquid waste materials that contaminate groundwater and soil. Related Post. Costs of treating well water, in those situations where the contamination has been discovered by neighbors was $1.12 billion between 1991 and 2004. Hope we can work together to fight pollution from our planet! For these reasons, nuclear waste is usually dumped deep beneath the ground. So without further ado, here are the top 10 cause of land pollution… In no particular order. Similarly, when we misuse the land resources, land pollution happens. The salinity they contribute can make life uninhabitable for crops and microorganisms. Overgrazing also causes loss of natural vegetation and compaction of the soil, disrupting the balance of natural microorganisms and often promoting the growth of harmful bacteria as well as contributing to the problems caused by erosion [17]. The damage wrought from fertilizer runoff from agriculture is well-documented. The construction of landfills is generally overseen by a governmental agency responsible for solid waste disposal and involve compliance with regulations to safeguard the leaching of their contents into the soil. During mining, many of these chemicals leak out into the soil, leading to soil contamination. Many of the replacement plants, like cotton, coffee, wheat and soybeans do not have deep roots and allow soil erosion. A Miracle or a Curse: What is Single Use Plastic? Left untreated, a lot of sewage waste tends to leak out of underground pipes, polluting the surrounding soul. While heavy machinery keeps spraying #monocrops with #pesticides and #fertilizers, millions of #family #farmers are applying agroecological approaches to redress those impacts and revive #rural areas. This waste often becomes toxic when exposed to air and water. Let’s have a look at these activities in detail to see how exactly pollution of land resources happens when they take place. Removal of even a portion of the canopy changes the environment of the forest as the canopy blocks the harmful sunlight and keeps in heat at night. Not as obvious are the oils, paints and other hazardous household wastes disposed of along roads because they are not accepted by most household waste collectors.

Effects of land pollution on the environment, Why Is Biodiversity Important to Ecosystems, many species do not survive the destruction of their habitats, easy runoff of fertilizers and other applied chemicals, apply highly toxic fertilizers, pesticides, fungicides, herbicides and insecticides, Urbanization contributes to land degradation. Nor is the problem confined to abandoned lots or illegal dumpsites. The expansion of housing developments, businesses, industry, infrastructure and agriculture all necessitated by an unprecedented population explosion over recent years accounts for humans modifying over 50 percent of the earth’s topsoil [2]. Industrial activities often release toxic and material wastes onto the land or into the atmosphere where they settle onto the land. It brings excess nitrogen to the water environment, creates algal blooms and consequent dead zones in the water where nothing can live. The heavy metals bring about harmful changes in the microbiological, mineral and physiochemical composition of soils around the mills [18]. Such roads tend to erode, and once the erosion begins, the road and land begin to deteriorate rapidly. Click here to cancel reply. Land developers capitalizing on urban sprawl cut down forests, as does the agricultural industry in order to increase the amount of land for growing crops. It’s simple.

Diseases Caused by Land Pollution. An urban planner looked at yet other needs the land provides people and estimated in 1996 that the land required to feed the population of London, supply their timber products and reabsorb their CO2 emissions by areas with growing vegetation was 125 times the size of the city [23]. Where there are no plants, there is no oxygen-generating mechanism (photosynthesis), no food or habitat for wildlife, amphibians, insects, and probably few, if any microorganisms to aerate, detoxify and regenerate the soil. The Love Canal incident was a major impetus for passage of the Superfund Act, a law imposing strict liability, that is responsibility that cannot be bargained away from injury and damages arising from exposure to the spilled toxic contents. The farmers could be educated by local extension agencies in sustainable practices like conservation tillage, cover crops, crop rotation and adding crop residuals to increase the fertility of their soil instead of fertilizers that cause greenhouse gas emissions, and land, water and air pollution. Of course, awareness regarding land pollution and the actual scale of the problem is of the utmost importance. Fertilizers, pesticides, insecticides, and herbicides are used with good intentions but have negative side effects. The first is where the soil gets contaminated, due to the addition of foreign elements.

Gravel & Dust From Unpaved Roads One of the most unnoticed of all the major causes of land pollution are the millions of miles of unpaved roads around the world. It is a global issue that needs to be fixed immediately. Requiring sustainable practices that help land regenerate and reestablish a community of beneficial organisms between crops would be helpful. Natural causes such as volcanic eruption, hurricanes or tornadoes can pollute land but since they are the natural causes, we are so helpless about it. The agricultural industry, yielding into the rising demand for food,  increases the use of synthetic fertilisers and pesticides to maximise the produce turn over. But, instead of taking care, all our activities have severely damaged the land, by inflicting it with catastrophic levels of pollution. Construction sites can always found to be littered with metal, wood, bricks, plastic etc. Land pollution refers to the deterioration of the earth’s land surfaces, at and below ground level.

Land that is once converted into dry or barren land can never be made fertile again, whatever the magnitude of measures to redeem it is. Following in on the heels of the industrial age, was the wave of urbanisation, that like a tsunami, just kept rising, leading to a vast scale of construction activities. Sources of soil pollution can be direct, for example, from dumping toxic chemicals directly on to a site, or indirect, for example where toxic chemicals leach through the soil from particulates that have settled from air pollution from a nearby lead smelter [1]. Forests absorb almost 20% of this heat, thus preventing soil degradation. Strip mines obviously remove the topsoil and contribute to erosion. Not to mention, the damage caused to the various life forms that depended on the forest for sustenance. Deforestation leaves the land exposed, which leads to rapid soil erosion. Land pollution can be defined as the destruction of the planet’s land surface.
