the world look like in 100 years? Will it look better than it looks today? Or worse? The truth is that nobody can see the future, however with the ever increasing human population, there is one major problem that has been getting worse over time: land pollution.
Most basically, land pollution is defined as the degradation of the ground and soils1. It is human influenced, either directly or indirectly, and leads to the worsening of soil quality and the destruction of the earth’s surface1.
Land pollution is a major problem around the world and is caused by a variety of factors. Some of main causes of land pollution include deforestation/erosion, agriculture, industry, mining, landfills/waste, and urbanization/construction2.
When land is cleared of the trees, the soil is stripped of its natural protection against erosion; this means that land that was previously lush and fertile is now being converted into dry, nutrient free land as a result of erosive processes like wind or water. Once the nutrients are removed from the land, they are very difficult to restore.
We can expect an increase in the volume of trash produced and this directly relates to the health of the environment near the cities. Additionally, where to store all the garbage becomes a bigger issue and how to dispose of waste properly is also of concern.
When waste is buried in landfills, if it is not done properly, chemicals can leach out and pollute the groundwater and soils. Additionally, sewage and sewage treatment leads to soil degradation and pollution of the land.
More cars and public transportation mean that there will be an increase in exhaust and an increase in air and land pollution. Oil, gasoline, and other pollutants are released into the atmosphere and settle on the soil leading to environmental destruction. Additionally, run off and construction effluent is also harmful.
Overall, there are many causes of land pollution and many cities and country sides have been converted into barren landscapes or brownfields3. However, there is hope.
These actions, with an increase in better land management practices can lead to a reduction in land pollution and a cleaner environment for generations to come.
