Some solutions to reducing global warming


Solutions to reducing global warming

Did you know?

eating 1 hamburger = cutting down 6 sq m of forest
eating 4 hamburgers = cutting down the size of a classroom of forest
eating 6 hamburgers = cutting down forest the size of a school stage
eating 37 hamburgers = cutting down forest the size of a school hall?








Global contributors of Green house gas emissions

In Percentage

Deforestation

25%

Livestock farming

18% [51%]

Transport [760 million vehicles]

14%

Industry

43% [35%]


Solution 1: Stop deforestation and start reforestation

To date up to 50% of the world's rainforest is lost
If 30% more is deforested, the remaining forest cannot survive
Deforestation rate is 50 million acres per year
Worldwide deforestation rate is 16 football fields per minute
In the Amazon, deforestation rate is 7 football fields per minute.


"70% of previously forested land in the Amazon rainforest was changed into areas for cattle grazing and growing feed crops" UN report

Deforestation in Australia
Of the 100 million hectares of land area that is being deforested:
Animal farming 70 million hectares
growing crops 25 million hectares
occupied by people 2 million hectares

Solution 2: Reduce livestock farming to reduce green house gas emission

UN 2006 Livestock's Long Shadow Report: Livestock industry produces:
18% of Global Greenhouse gas emissions
37% of Global methane (which is 23 times CO2 global warming power)
65% of Global N2O (which is 296 times CO2 global warming power)

"Raising animals generate more greenhouse gases (18%) than all the 760 million cars and trucks in the world combined (14%)" UN FAO Report.

Producing 1 kg of beef generates 36.4 kg of CO2
Producing 1kg of beans generates 0.6 kg of CO2
Meat industry requires lots of refrigeration and transport (energy inefficient process)
Switching to vegetarian diet reduces 1.5 tons of CO2 emissions per year










Tons of manure from livestock farms flow into underground water and into seas causing large areas of Dead Zones.

Conserve the world's food and water resources
Food fed to animals:
75 % of world's soy bean
50% of world's corn
36% of world's grains

In 2007, food fed to animals was 760 million tons
in 2007, world hunger figure was 900 million people
The grains fed to livestock would be able to feed 2 billion people!

Water requirements of livestock- UN FAO Report
Stockholm International Water Institute states that the agricultural sector (growing of crops and livestock) accounts for 70% of the world's water usage

To produce 1 kg of

Amount of Water Needed [litres]

Maize

900 lt

Rice

3000 lt

Chicken

3900 lt

Pork

4900 lt

Beef

15,500 lt


15,5000 litres of water is sufficient for a man to shower for 6 months!

Solution 3: Support Organic farming

"Practical organic agriculture if practised on the planet's 3.5 billion tillable acres, could seqester nearly 40% of current CO2 emissions.." US Rodal Institute


Solution 4: Green Energy

Solution 5: Practise the 3Rs (Reduce, Reuse and Recycle)

More about solutions 4 and 5 on a later blog post.
