Livestock emissions are responsible for 18% of the greenhouse gases that cause global warming. That's more than all forms of transportation put together.
Cows' farting and burping must be brought under control because they're causing global warming problems, a climate change expert has warned.

Just one cow gives off enough harmful methane gas in a single day to fill around 400 litre bottles, which is really bad for the environment.

The gas goes up into the atmosphere and makes the hole in the ozone layer bigger, worsening global warming.:))
