THE GREENHOUSE EFFECT

THE GREENHOUSE EFFECT
Consequences
Rise of the earth's temperature
Change of weather
Ice at the North and South Poles will start
to melt
Level of the sea will rise
Floods
Problems of food
E.g. USA and USSR too dry for farming
Other countries will become wetter
Soil not rich
Impossible to grow the same amount of
food as before
Origin
The atmosphere is a blanket of gases and
keeps the planet's temperature at about
15ºC.
How? By trapping some of the sun's heat
Now, because of pollution, there are more
gases in the atmosphere.
This means that the earth is getting hotter.
Scientist call this problem 'The greenhouse
effect'.
Solutions
We can't stop it, but we can make it slow it
down
Conserve fossil fuels
Conserve rainforests
Countries must protect their rainforests, not
destroy them
Use natural energy
Sun
Solar energy
Sea
Marine energy
Wind
Wind energy
Ban CFCs
Reduce your waste
Stop using plastic bags
Instead of using disposables, focus on
reusable
Recycle as much as you can
Compost your food waste
Choose organic over commercial farming
Main greenhouse gases
Carbon dioxide (CO2)
Burning fossil fuels
Burning rainforest trees
Fewer and fewer trees
More and more CO2
CFSs
Aerosol / Spray
Refrigerators
Plastic boxes
CFCs molecules can trap a lot of heat and
destroy the air.
This is making the top level of the
atmosphere (ozone) thinner
Methane
Cow's stomachs
Nitrous oxide
Fertilizers
Rubbish
