• Rainforestarwidelyu believed by laymen to
contribute a significanamounothe world's
oxygen, although it is now accepted by
scientists that rainforests contribute little
net oxygen to the atmosphere and
deforestation has only a minor effect on
atmospherioxygen level.
• However, the incineration and burning of
forest plants to clear land releases large
amounts of COwhich contributes to global
warmin.
• Scientists also state that tropical
deforestation releases 5 billion tons of
carbon each yeainto the atmospher.
• Forests are also able to extract carbon
dioxide and pollutants from the airthus
contributing to biosphere stabilit.

• Every time we burn fossil fuels such as gas,
coal or oilcarbon dioxide is released into the
atmospher. In a natural carbon cycle, carbon
dioxide is rabsorbed by plants and tree.
However, we are burning fuels where the
carbon dioxide has been trapped under the
earth's surface for millions of yearsand we're

• The effecoalthis extra carbon dioxide in the
atmosphere is that the overall temperature of
the planet is increasing (global warming.
Whilst the average global temperature is
increasingon a datday levethe climate is
changing in unpredictable way. To try and
reduce the risk of ever more extreme weather,
we need to reduce how much fossifuewe are
