TEXTO - COW THREAT


Cow  Threat



Cows are walking machines. They transform materials ( grass, hay, and feed) into finished products ( milk, beef, leather and so on).
As any factory, cows produce wast. Solid wast is eliminated through the rear end of these "Complexe machines" and is used as fertilizer.
The fermentation process in their four stomachs producers gas. These walking machines have two chimneys one in the front of the and, the other in the rear end. Gaseous emissious through the front and chimney are called burps. Cows burp a lot. Every minute and a half. These burps release methane gas. Methane is dangerous to the planet because it contributes to the greinhouse effect.
The world population is growing very fast. That means there are more people eating beef. Consequently, there is more cattle  more walking machines producing more methane gas.
This is problem, but very few people want to change their eating habit.What about you?
