Pollution and Nutrients

What is pollution?

Pollution is the introduction of something NASTY into the environment, usually put there by humans, but can also be a result of natural disasters.

Pollution and the environment don’t mix – the environment can only take so much pollution before it starts to show signs of sickness. Just like our bodies if we don’t take care of them. You must always remember that water flows DOWNSTREAM… whatever we put in the water in one spot will eventually reach someone in another spot further downstream… it doesn’t just GO AWAY!

What are the different types of pollution?

LAND Pollution

Pollution of the Earth’s natural land surface by industrial, commercial, domestic and agricultural activities.

So where does it come from?

Some of the main ways we pollute the land is from:

  • Chemical and nuclear plants
  • Factories
  • Places that make oil and gas
  • Human sewage
  • Oil and antifreeze leaking from cars
  • Mines
  • Littering
  • Overcrowded landfills
  • Cutting down forests
  • Construction garbage

The best way to prevent land pollution is to REDUCE, REUSE AND RECYCLE

AIR Pollution

Accumulation of dust, particles, smoke and other things we can’t see in the air that we breathe and it can contain chemicals that are not good for our health.

So where does it come from?

  • Cars and trucks
  • Burning of coal (to produce energy)
  • Acid rain
  • Noise pollution from cars and construction
  • Power plants (to produce energy)
  • Factories
  • Large ships
  • Paint fumes
  • Aerosol sprays
  • Wildfires
  • Tobacco smoke
  • Nuclear weapons

WATER Pollution

Occurs when materials (natural or man-made) enter a lake or river and hurt the critters living in that water. It also hurts the water itself, sometimes so badly you can’t drink or even swim in it. Remember…everything that happens in our watershed affects everyone, because water links us all!

Did you know? One litre of oil can contaminate up to 2 million litres of water.

So where does it come from?

Some of the main sources of water pollution are:

  • Factories
  • Refineries
  • Waste treatment facilities (places that clean the water from the lake so we can drink it)
  • Mining
  • Pesticides, herbicides and fertilizers
  • Human sewage
  • Oil spills
  • Old or uncared for septic systems
  • Soap from washing your car
  • Oil and antifreeze leaking from cars
  • Household chemicals
  • Animal waste
