Answers
Effect
•Use of fertiliser , pesticides , fungicide and chemical waste .
•Deforestation leads to loosening of soil resulting in landslides.
Solution
•Use organic fertiliser made of cow dunk and organic waste
•Plant more trees.
Explanation:
Causes of Land Pollution
1. Deforestation and soil erosion
Deforestation carried out to create dry lands is one of the major concerns. 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. Land conversion, meaning the alteration or modification of the original properties of the land to make it use-worthy for a specific purpose is another major cause. This hampers the land immensely.
2. Agricultural activities
With the growing human population, demand for food has increased considerably. Farmers often use highly toxic fertilizers and pesticides to get rid off insects, fungi and bacteria from their crops. However with the overuse of these chemicals, they result in contamination and poisoning of soil.
3. Mining activities
During extraction and mining activities, several land spaces are created beneath the surface. We constant hear about land caving in; this is nothing but nature’s way of filling the spaces left out after mining or extraction activity.
4. Overcrowded landfills
Each household produces tonnes of garbage each year. Garbage like aluminum, plastic, paper, cloth, wood is collected and sent to the local recycling unit. Items that can not be recycled become a part of the landfills that hampers the beauty of the city and cause land pollution.
5. Industrialization
Due to an increase in demand for food, shelter, and house, more goods are produced. This resulted in creation of more waste that needs to be disposed of. To meet the demand of the growing population, more industries were developed which led to deforestation. Research and development paved the way for modern fertilizers and chemicals that were highly toxic and led to soil contamination.
7. Nuclear waste
Nuclear plants can produce a huge amount of energy through nuclear fission and fusion. The left over radioactive material contains harmful and toxic chemicals that can affect human health. They are dumped beneath the earth to avoid any casualty.
8. Sewage treatment
A large amount of solid waste is leftover once the sewage has been treated. The leftover material is sent to landfill site which end up in polluting the environment.
Effects of Land Pollution
1. Soil pollution
Soil pollution is another form of land pollution, where the upper layer of the soil is damaged. This is caused by the overuse of chemical fertilizers, soil erosion caused by running water and other pest control measures; this leads to loss of fertile land for agriculture, forest cover, fodder patches for grazing, etc.
2. Change in climate patterns
The effects of land pollution are very hazardous and can lead to the loss of ecosystems. When land is polluted, it directly or indirectly affects the climate patterns.
3. Environmental impact
When deforestation is committed, the tree cover is compromised. This leads to a steep imbalance in the rain cycle. A disturbed rain cycle affects a lot of factors. To begin with, the green cover is reduced. Trees and plants help balance the atmosphere, without them we are subjected to various concerns like Global warming, the greenhouse effect, irregular rainfall and flash floods among other imbalances.
4. Effect on human health
The land when contaminated with toxic chemicals and pesticides lead to the problem of skin cancer and the human respiratory system. The toxic chemicals can reach our body through foods and vegetables that we eat as they are grown in polluted soil.

5. Causes air pollution
Landfills across the city keep on growing due to an increase in waste and are later burned which leads to air pollution. They become home for rodents, mice, etc which in turn transmit diseases.
6. Distraction for tourists
The city loses its attraction as a tourist destination as landfills do not look good when you move around the city. It leads to a loss of revenue for the state government.
7. Effect on wildlife
The animal kingdom has suffered most in the past decades. They face a serious threat with regards to the loss of habitat and natural environment. The constant human activity on land, is leaving it polluted; forcing these species to move further away and adapt to new regions or die trying to adjust. Several species are pushed to the verge of extinction, due to no homeland.
Solutions for Land Pollution
1. Make people aware of the concept of Reduce, Recycle and Reuse.
2. Reduce the use of pesticides and fertilizers in agricultural activities.
3. Avoid buying packages items as they will lead to garbage and end up in the landfill site.
4. Ensure that you do not litter on the ground and do proper disposal of garbage.
5. Buy biodegradable products.
6. Do organic gardening and eat organic food that will be grown without the use of pesticides.
7. Create dumping ground away from residential areas.
