COW THREAT (I ANO- 2011)
Cows are walking machines. They transform
raw
materials
(grass,hay,water,and feed) into finished products(milk,bef,leather,and so on).
As any factory, cows produce waste. Solid waste is elimineted through the
rear end of these “complex machines”, and is used as fertilizer.
The fermentation process in their four stomachs produce gás. These
walking machines have two chimneys: one is in the front end,the other in the
rear end. Gaseous emissions through the front end chimney are called
burps.Cows burp a lot. Every minute and a half. These burps release methane
gás. Methane is dangerous to the planet because it contributes to greenhouse
effect.
The world population is growing very fast. That means there are more
people eating beef.Consequently, there is more cattle, more walking
machines, roducing more methane gás.
This is the problem,but very few people want to change their eating
habits. What about you...
