INTRODUCTION OF ENVIRONMENTAL POLLUTION
Our environment is a major aspect of our life today. Many of us don't take our Earth seriously and think that as long as pollution doesn't hurt them they can go ahead and throw garbage on the ground or spill oil down the drain. Well to many people have that theory and they are killing off our Earth and also physically harming themselves from the air they breath and the water they swim in. Our Earth is fragile like a human and people don't know.

DEFINITION OF ENVIRONMENTAL POLLUTION
Environmental pollution is the build-up and concentration of toxic levels of chemicals in the air, water, and land, which reduces the ability of the affected area to support life. Pollutants may be gaseous- ozone and carbon monoxide, for example; liquid discharge from industrial plants and sewage systems; or solid-landfills and junkyards.

KINDS OF ENVIRONMENTAL POLLUTION
There are actually SEVEN different kinds of environmental pollution. Most people can name them are;
o Air pollutiono Land pollutiono Water pollutiono Noise pollutiono Light pollutiono Thermal pollutiono Visual pollution
Listed below are each kind and examples to help you understand just how we can affect the environment and each other.

AIR POLLUTION DEFINITION;AIR POLLUTION IS THE CONTAMINATION OF AIR BY SMOKE AND HARMFUL GASES, MAINLY OXIDES OF
CARBON, SULFUR, AND NITROGEN.

EXAMPLE OF AIR POLLUTION
Some examples of air pollution include: Exhaust fumes from vehicles The burning of fossil fuels, such as coal, oil or gas Harmful off- gasing from things such as paint, plastic
production and so on Radiation spills or nuclear accidents Air pollution is linked to asthma, allergies and other
respiratory illnesses.

EXAMPLE OF LIGHT POLLUTION;
Some examples of what causes light pollution: Street lamps that shine light in all directions, instead of
with a hood to point light downward toward the street. Unnecessary lights, especially around the home
Light pollution uses more energy (by shining more light up instead of down), may affect human health and our sleep cycles and most importantly, corrupts our kids telescopes and their curiosity.
Wastage of light pollution
