The Legislation
---Regulate the burning of fossil
fuels and logging practice
Global Warming
• Global warming is regarded as a period of time that the
earth's atmosphere and ocean temperature rise due to
the greenhouse effect caused by the phenomenon of
climate change.
Introduction
• Nowadays, the circumstances over the world about
global warming are un-optimistic.
• The main factors of global warming are PLANTS and
FOSSIL FUELS
• Legislation should be introduced to reduce fossil fuel
emissions and the cutting of plants.

1. The Benefits of Plants
Forest can absorb 850kg CO2 and release 650kg O2
each kilometer trees. Therefore, forest is a huge natural
CO2 reservoir for the earth.
6CO2+12H2O→6O2+6H2O+C6H12O6
C6H12O6+6H2O+6O2→6CO2+12H2O+energy
The plants' cold resistance is decreasing because of the
abnormal climate. So it will destroy the balance of CO2
when a large number of plants died after winter.
2. The Negative Effects of Fossil Fuels
• Some gases such as CO2, methane, chlorofluorocarbon that human being made during daily activities
have the ability to absorb ultra-red radiation. These
gases are called GREENHOUSE GASES.
• When we drive the cars; when the factories work, every
time we burning the fossil fuels means there are lots of
greenhouse gases release. They are the crime culprit of
global warming.
3. The Importance of Legislation
• Current situation:Though global warming becomes a
severe problem nowadays, there are still lots of people
didn't realize it and keep ruining the environment.
• Definition: Legislation is a normal and serious way to
regulate the behavior of people.
• Purpose: The legislation will effectively control the
number of plants and emission load of fossil fuels. It will
slow down the speed of global warming.
Conclusion:
• Making legislation about plants and fossil fuels is no time
to delay. Beside the legislation, as a citizen, we should
increase the awareness of prevention of global warming
and destruction of our planet. There are many measures
we can take such as planting more trees, using clean
fuels. I trust that we will have a better future via our
efforts.
Only One Earth!!!!!!!!!
