the bad name that global
warming has given greenhouse gases, they are actually
necessary for human life on Earth.
greenhouses gases, the Earth would be a cold planet, much
too cold for human life to have ever evolved.

effect was first recognized in the 19th century during the
Industrial Revolution. Since then, industry has continually
contributed a lot of greenhouse gases to the atmosphere, much
more than the amount that is naturally there. This causes
the atmosphere to warm up, and if it continues, will make
life uncomfortably hot for humans and all the other life on
of greenhouse gases
Despite all the attention of pollution emissions by cars,
it is petroleum oil
and other fossil fuel power plants which are the largest greenhouse
gas contributors. These are followed by industrial processes,
and in third place, transportation emissions. Other major
causes of the greenhouse effect are agricultural by-products
and various fossil fuel extraction and refinement processes.
There is hope for a solution to global warming, however, because
besides efforts to curb our output of greenhouse gases, scientists
are working on a number of different ways that greenhouse
gases can be removed from the atmosphere.

these proposed methods include fertilizing the ocean with
iron to encourage plankton growth; using massive amounts of
chemical scrubbers to clean the atmosphere; or dumping limestone
in to the ocean, which promotes natural carbon
dioxide removal processes.
These man-made solutions are attractive, but they only address
the symptoms, rather than the root of the problem. Even if
they are implemented, it will only postpone the greenhouse
