Global Warming: The Cause, Situation, Countermeasures
Causes of global warming
There are many types of causes of global warming.
One of them is the burp of cows and sheep.
The methane gas contained in their burp destroys the ozone layer.
The ozone layer is like a film in the sky that protects the earth from UV rays.
In addition, methane gas has a high greenhouse effect.
The greenhouse effect is the effect of keeping the temperature constant.
The greenhouse effect of methane gas is about 20 times that of carbon dioxide.
More than 20% of the methane gas in the atmosphere comes from cattle and sheep burp.
