Environmental Pollution – An introduction to Land, Air and Water Pollution

What is Environmental Pollution?

The environment is made up of systems, cycles, and specialized relationships between living and non-living elements. When everything’s working the way it should be, all the living organisms within the environment, including humans, are healthy and thriving.

But when something harmful is introduced to the cycle, or part of the cycle is disrupted somehow, it can cause a chain reaction of problems right through the rest of the system. These changes can really hurt the health and well being of living organisms. One of these negative changes is pollution, which is the result of unnatural elements entering the environment. Unfortunately, humans are usually at fault.

Anything that’s harmful to the environment is pollution. Litter, car exhaust, motor oil, used tires, smoke, chemicals – all of these can have an instant or a gradual impact on the health of our earth.

But even though there’s been a lot of damage done to the environment by pollutants, that doesn’t mean it’s “game over” for Earth. There are two ways to tackle the problem. First, clean up what we can. And second, take action to prevent further pollution.

Land Pollution:

Most of the pollution on land comes from litter. People toss away garbage instead of disposing of it properly, which clogs up the land, attracts pests such as insects and rodents, and even harms the soil and the critters that live there if it contains chemicals. If garbage kills the plants in an area by covering them up, it affects the food chain, since green plants are the start of every chain. It also affects the air quality, since plants help clean the air.

Air Pollution:

Some pollutants that enter the air come from natural sources. For example, When a volcano erupts, volcanic ash blasts into the air and can remain there for years. Other natural sources of air pollution include smoke from forest fires, and dust and sand from storms.

While there are some natural sources of air pollution, the majority of air pollutants come from things we do ourselves—or things people have invented, such as the combustion engine.

Airborne pollutants make it tough to breathe and can even cause diseases like cancer. One problem is the way winds criss-cross the globe, picking up pollutants and carrying them all over the world. This is how areas far away from where the actual pollution is created can become affected, too. Air pollution is not just a local concern.

Water Pollution:

When sewage, oil, chemicals, and other pollutants enter the water cycle, it can be devastating and even deadly. Sediments that collect in the water from trash or chemicals in the water prevent fishes from filtering oxygen through their gills, and they can suffocate. When the dissolved oxygen in the water drops below a certain level (two to five parts per million gallons of water), many types of fish and aquatic animals can’t survive. Aquatic plants also are “choked” and die, disrupting the food chains.

Water Pollutants can come from various sources:

  • Sewage and farm waste can introduce harmful bacteria.
  • Herbicides, pesticides, and fertilizers from agriculture can wash into the water.
  • Beach-goers and boaters often leave their trash behind.
  • Silt from construction or land clearing sites can enter the water through runoff.

      The chemicals in cigarettes kill the Daphnia, a microscopic aquatic animal that is important in the marine food chain.

      Noise pollution is a very real threat to wildlife—very loud noises from machinery or vehicles can disrupt animals’ migration and breeding and limit their choice of habitat.

      Poison ivy likes carbon dioxide. The more carbon dioxide in the environment, the bigger poison ivy grows. And the rash you get from it? Much more itchy!

    2. Two days workshop on environmental pollution and its effects on human beings was held in Chandigarh, India, a few days ago. The agenda was focused on continuous spread of poison in fruits, vegetables and other agricultural products which is quickly aggravating pollution.

      The delegates while taking part in the special seminar organized by Centre for Research in Rural and Industrial Development, stressed upon the need of saving the environment from such hazardous situation of land pollution.

      Delegates warned that the increasing and continuous use of fertilizers, chemicals and pesticides are not only responsible for the dreaded diseases like cancer but also changes in the hormonal system in the human body.

      Punjab is on the verge of a very alarming stage. There is a great need of mounting pressure on all the political leaders and parties to make a serious note of this danger and include this in their election manifesto to save the mankind from the probable danger of environmental pollution. The promotion of organic farming can do a lot in this regard.

      I have been researching and can not find anything on this topic.
      I reload rifle ammunition. Very small amount per year. The question is. When i clean my rifle brass in a tumbler with corn cob media. (crushed up corn cobs) I end up with about five pounds per year that needs to be disposed of.
      How should i dispose of it? Is it safe to use in compost pile? Is it classified as Haz-Mat material?

      Thank you for any help with this.
