Land Pollution

What is land pollution?

When we first think of pollution we often think of trash by the side of the road. This type of pollution is called land pollution. Land pollution is anything that damages or contaminates the land.

Causes of Land Pollution

There are many causes of land pollution from the trash we throw away in our homes to waste produced at giant factories. Sometimes chemicals from the trash can contaminate the soil and eventually the groundwater we need for drinking. Effects on the Environment

Land pollution can be one of the most visible types of pollution. You see trash outside of buildings or on the side of the road. You may see a large landfill or dump. This type of land pollution not only can hurt animals and their habitats, but also is ugly and destroys the beauty of nature.

Other types of land pollution like mining, farming, and factories can allow for harmful chemicals to enter into the soil and water. These chemicals can cause animals and plants to die, disrupting the food chain. Landfills release the greenhouse gas methane, which may lead to global warming.

Effects on Health

Different kinds of land pollution have been known to have adverse affects on the health of animals and humans. The harmful chemicals that can get into the soil and water can cause cancers, deformities, and skin problems.


Landfills are areas where garbage is placed in the land. Modern landfills in developed countries are designed to keep harmful chemicals from polluting the water. Some of the newest landfills even try to capture methane gas from escaping and use it do produce energy. In the United States there are a lot of laws and regulations to try and keep landfills from harming the environment.

What is biodegradable?

Trash that is made of organic substances will eventually decay and become a part of the environment. This type of trash is called biodegradable. Different types of materials take different amounts of time to decay. Paper can decompose in around a month, but it takes a plastic bag over 20 years to decompose. Scientists predict that it could take a glass bottle about 1 million years to biodegrade and that some materials, like Styrofoam, will never biodegrade.

What can you do to help?

Here are four things people can do to reduce land pollution:
  1. Recycle - Around 33 percent of trash in the United States is recycled. When you recycle you add less land pollution.
  2. Produce less trash - Some ways to reduce trash include not using a napkin or paper towel unless you absolutely need one, drinking water from a cup rather than a plastic bottle, and being sure to properly dispose of harmful trash like batteries and computer equipment.
  3. Pick up trash - Don't be a litter bug! Also, you can help out by picking up trash when you see it lying around. Kids make sure to ask your parents for help before you pick up strange trash.
  4. Composting - Get with your parents or school and start a compost heap. Composting is when you collect organic waste and store it so it breaks down to where it can be used for fertilizer.
