Population and Pollution

3 diffrent types of pollution:

1.Carbon Dioxide:From increased burning of fossil fules which may increase,which may increase the green house effect and global warming.

2.CFC:from aerousols,which destroy the ozone layer

3.Sulfur Dioxide,from burning fossil fuels which causes acid rain.

The human population is happening beacuse the birth rate is exeeding the death rate.

The amount of pollution caused per person or organisation is called the carbon foot print.This meausres the totla greenhouse gas given off by a person or organisation whithin a certain time.

There are advantages to diffrent methods of measuring pollution:

-using indicator or oraganisms is cheaper does not need equiment that can go wrong and monitors pollution levels oer long periods of time.

using direct methids can give more accurate results at any specific time.
