  Burping sheep increase global warming
Updated 20 December 2001, 12.53

Sheep in New Zealand are burping so much that they are damaging the environment.

The wooly creatures' burps are actually producing more than half of the country's greenhouse gas.

Windy sheep

The animals fill up with wind when they eat grass and this can only be released by burping.

When they burp they produce a greenhouse gas called methane which adds to global warming.


Burp measurers

Scientists have fitted some sheep with special machines to measure exactly how much gas is produced when they burp.

They hope this will help them to invent food that will stop the animals producing so much wind.

Wind tax

A farmer from New Zealand said: "They can blow up like a huge balloon and it's all gas."

If scientists can't stop sheep burping so much, farmers will be taxed for the wind that their animals produce.
