Now look at the complete essay:
 
List some of the causes and effects of global warming. Offer one
solution that might help slow or stop the problems associated with
global warming.
Global warming is causing increasing concern around the world as the health effects of
this problem are becoming more understood. As scientists study the causes and effects of
global warming, public awareness of this problem is increasing. 
Now that people better
understand that pollution is the main cause of global warming, and that the effects of
pollution include ozone depletion and the greenhouse effect, solutions can be put into
place to minimise its effects.
Firstly, the causes of global warming stem from pollution. Some of the main producers of
air pollution are factories and cars, which emit toxic gases like carbon dioxide into the
atmosphere. Also, as the population of the earth grows, more and more farm animals are
needed to feed the growing population, and it is now known that farm animals emit
methane gas. Methane, carbon dioxide and other chemicals deplete the ozone layer of the
atmosphere and are causing a large hole to form in the ozone layer. This hole allows
ultraviolet rays to come through and, as a result, the earth’s temperature is beginning to
rise.
The effects of global warming are numerous. Scientists now know that the ultraviolet
rays coming through the depleted ozone layer are harmful to humans and are causing
increasing cases of skin cancer. Also, rising temperatures are causing changing weather
patterns and an increase of natural disasters like droughts, floods and fires.
As we realise the extent of the damage being done, we can take steps to slow the effects of
global warming. New technologies like cars that use hydrogen as fuel emit only pure
water. And renewable energy sources like wind, water and solar power do not release
harmful emissions into the atmosphere.
In conclusion, as the causes and effects of global warming are better understood,
individuals, communities and countries can take steps to slow and eventually stop global
warming.
