That's Why We Plant Trees @ Food & Trees for Africa

Keep it green


Greenhouse gases trap some of the sun’s energy within our atmosphere and increase temperature of the Earth’s surface and atmosphere. That is called greenhouse gas.


Traffic
· One quarter of all man – made CO2 emissions is transportation – related.
· 75 million cars worldwide emit a total of approx. 2.25 billion of CO2 each year.


Industrialization
· Industrial production is responsible for more than half of all CO2 emmissions.
· Largest quantities of CO2 emitted by energy producers and energy – intensive industries.
· New filtration technologies could reduce CO2 emissions by 30 to 50%.


Deforestation
· A quarter of CO2 emissions worldwide result from deforestation.
· Net forest loss since 2000: 7.3 mill. Hectares per year (roughly the size of Panama).
· Improvement measures: afforestation, reforestaton, avoided deforestation.


Deforestation
· Agriculture is a huge source of methane and nitrous oxide, and responsible for 15% of worldwide greenhouse gas emissions.
· Climate-friendly agricultural management (i.e. organic farming) could reduce emissions significantly.

THE ACCELERATED WARMING PROCESS HAS A NUMBER OF DANGEROUS IMPACTS, BEING THE FOLLOWING;


Melting glaciers/icecaps
· Since the early 1960s, mountatin glaciers around the world have experienced an estimated net loss of over 4 000 cubic kilomitres of water; this loss was more than twice as fast during the 1990s as fast during the 1990s as in the previous decades.
· Projection: 4 degrees Celsius rise in average global temperatures would cause nearly all of the world’s glaciers to melt,resulting in rising sea levels.

Increase of storms
· Globally, the annual number of strong storms doubled from 8 (early 1970s) to 18 (2000-2004).
· Hurricane Katrina in 2005 was the 6th largest hurricane on record, and caused over 60 billion US dollars in damage.
· The magnitude and damages caused by the 27 tropical storms in the Atlantic during 2005 were the highest yet recorded.

Desertification
· 2 bill. People in 110 countries are affected and threatened by accelerating desertification.
· The UN projects that 30% of the world’s fertile land surface will turn into desert in the future.
· Example: In Niger, 250,000 hectares, an area about the size of Luxemboug, becomes desert each year.
