cause and effect outline revised

Thesis statement:
The emission of high pollutant increases its effect on global warming.

The outline(chain rule):
Human action casuing the emission of pollutant
ex. the use of cars, the use of a/c.s
->
High amount of CO2 is being emitted
->
Causes the breakdown of ozone layer
->
Increases the Earth's sea level as the amount of sunlight increases
->
more heat comes to the surface of the Earth
->
(occurs simultaneously with previous step)
People tend to use air conditioners with the rise of temperature/
overuse of energy
->
The concept overlaps and the cycle continues which will ultimately cause the global warming.
