Land pollution is an equally serious problem and often also contributes to water pollution through percolating down to the water tables or erosion runoff into open waters. 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].

It can also simply be degradation from transforming the land by clearing it so that beneficial organisms can no longer provide services supporting growth and protect it from further erosion. This human activity appears more than a little reckless when considering that it takes years to naturally produce 2. Land pollution, whether it is a barren space where nothing can grow but a few weeds or a site that harbors garbage and debris, like old tires, gas cans and plastic bags is an aesthetic drain. Studies consistently show the health benefits of enjoying nature at its finest, with its lush growth, clean air and water renewing world-weary urbanites [4].

Conversely, while not documented, no one would dispute that the effect of seeing barren or polluted land is depressing. But there are even more serious problems how land pollution affects the environment. This has further consequences for us as part of the web of life.

The web has been broken when the biodiversity that enables life has been destroyed. 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.

Soil that is filled with toxic chemicals will not sustain life and poses a health risk to children who might play there.

Prior to being banned in 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. They were disposed of not only in landfills, but through illegal dumping and by burning. The ash and particles from burning fell to the earth and were absorbed by the soil. Today, almost all soil has at least small amounts of PCB [6].

Children playing in areas of PCBs can absorb the toxins through their skin. And studies support evidence of their carcinogenic effects as well as various other negative immune, reproductive, neurological and endocrine effects [7]. Toxic chemicals can leach into the soil and reach the water table below, often a source of drinking water for the nearby community.

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. The toxic chemicals can lodge in the ground sediment of the stream, adversely affecting the aquatic life that sustains itself by sheltering and feeding there.

The toxic chemicals absorbed via ingestion or skin absorption make their way up the food chain as they are stored in the tissue of the marine life and magnified as larger fish eat more of the tinier prey, so that the meal can be quite toxic by the time the fish makes it to our dinner plate. It is not just direct pollution of toxic chemicals that can cause these problems.

Nor is the problem confined to abandoned lots or illegal dumpsites.

10 Lines on Land Pollution

Land pollution is a major problem around the world and is caused by a variety of factors. 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]. In the Amazon rain forest in Brazil, an area the size of a football field is clear-cut by loggers every second [9].

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. Obviously, a rain forest gets a lot of rain, heavy rain and without a forest canopy to buffer the downpours and without ground cover to hold the soil intact, the rich soil of the forest floor is easily washed away.

Along with the topsoil go the nutrients necessary to regenerate growth. It is estimated that eighty percent of land animals and plants live in forests. 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. Many species cannot adapt to these severe changes in temperature and many species do not survive the destruction of their habitats [10].

Loggers are not the only ones responsible for the rapid deforestation of the earth. 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. In fact, agriculture has been found to be the direct cause if 80 percent of deforestation worldwide [11]. Much of this agricultural land is required to grow crops for animal feed, primarily cattle for the beef industry.

The land is also used for cattle grazing [12]. The world population increase and increased demand for a food supply is causing forests and grasslands to be converted to farmland. Natural vegetation has deep roots that hold the soil in its place. Many of the replacement plants, like cotton, coffee, wheat and soybeans do not have deep roots and allow soil erosion. This means that flooding is worsened as the land no longer has the ability to absorb excess rainfall [13].

It also allows for easy runoff of fertilizers and other applied chemicals. Farmers routinely apply highly toxic fertilizers, pesticides, fungicides, herbicides and insecticides directly on to the crops and land. The contamination destroys the healthy organisms responsible for generating new vegetative growth. The change in chemical composition of streams and rivers from this chemical runoff upsets the natural balance of life causing other, often foreseeable but unanticipated problems. The damage wrought from fertilizer runoff from agriculture is well-documented.

It brings excess nitrogen to the water environment, creates algal blooms and consequent dead zones in the water where nothing can live. A dead zone at the mouth of the Mississippi River from fertilizer runoff primarily from corn fields along its banks, covers more than square miles 20, sq km in the Gulf of Mexico during the summer months. The runoff is not only continuing, unabated, but is expected to increase as the demand for corn to feed cattle and as a biofuel increases [15].

The herbicide atrazine mentioned above has been found to cause changes in the reproductive systems in frogs, turning male frogs female.. The high cost of filtering agricultural chemicals in wastewater treatment plants is ultimately absorbed by the drinking water consumer and one must question whether that is a fair allocation of expenses or whether the agriculture specialist responsible for the pollution should bear the cost, resulting in a better likelihood of more responsible decision-making.

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].

Ten Lines on Land Pollution in English

Industrial activities often release toxic and material wastes onto the land or into the atmosphere where they settle onto the land. While most developed countries now regulate land dumping and emissions, the regulations balance the costs to industry and do not necessarily adequately safeguard the integrity of our biosphere or more specifically, human health. For example, although cassava is the third most consumed carbohydrate in the world, the practice of dumping its toxic byproducts, that is, hazardous solid and liquid residues directly onto the land, continues in Nigeria today.

A recent study of the effects on the soil of dumping cassava showed many deleterious effects to the previously arable land. The heavy metals bring about harmful changes in the microbiological, mineral and physiochemical composition of soils around the mills [18]. This is where the earth is either scraped or blasted to get to the mineral seams.

The balance of mining is done underground, where pillars support the earth while work is performed underground and at the end, removed or simply left to collapse. Strip mines obviously remove the topsoil and contribute to erosion. In many developed countries, regulations now require land reclamation when the project is over.

Moreover, it affects wildlife a lot. Some animals may suffer from hearing loss while others become inefficient at hunting. It is very important to understand noise pollution in order to lower its impact on the environment. Radioactive pollution is the presence of radioactive substances in the environment.

It is highly dangerous when it occurs. Radioactive contamination can be caused by breaches at nuclear power plants or improper transport of radioactive chemicals.

Radioactive material should be handled with great care as radiation destroys cells in living organisms that can result in illness or even death. Environmental pollution has negatively affected the life of both animals and human-beings. The only way to control current environmental issues is to implement conservation methods and create sustainable development strategies.

We should find some effective solutions in order to restore our ecological balance. First of all, we should make sustainable transportation choices. We should take advantage of public transportation, walk or ride bikes whenever possible, consolidate our trips, and consider purchasing an electric car. It is very important to make sustainable food choices.

Land Pollution: Causes, Effects, And Solutions For The Future

Choose local food whenever possible; buy organically grown vegetables and fruits or grow your own. People should conserve energy. Turn off electronics and lights when you are not in the room. Consider what small changes can lead to big energy savings. Use energy efficient devices. It is also essential to understand the concept of reduce, Reuse and Recycle. Try to buy used items whenever possible.

Choose products with minimal packaging. Buy reusable items.

Remember that almost everything that you purchase can be recycled. Conserve water as much as possible. Dispose of toxic waste properly. Do not use herbicides and pesticides. Use natural, environmentally friendly chemicals for your everyday chores. Environmental pollution is one of the biggest problems caused by human activities that we should overcome to see a tomorrow and guarantee our descendants a healthy life. There are many environmental concerns for communities around the world to address.

We should always remember that pollution problems affect us all so each of us has to do his or her best to help restore ecological balance to this beautiful place we call home.
