Hello and welcome to 6 Minute English from BBC Learning English.
I'm Rob.
And hello, I'm Finn.
Now Finn, there's nothing I like more than tucking into a juicy steak,
munching on a hamburger or chewing on a nice piece of roast beef.
Oh, it does sound good, doesn't it?
But meat eaters, like us, might need to think again about the amount we eat.
Yes, that's right, because in the programme today,
we're discussing how eating meat can add to the problem of greenhouse gas.
Greenhouse gas is a type of gas that stops heat escaping from the atmosphere and causes a greenhouse effect.
It warms up our planet and that leads to climate change.
Yes, and that's not a good thing.
We've heard in the past about greenhouse gas being caused by pollution from factories.
And from using containers of things like paint or perfume,
which is kept under high pressure so that it can be sprayed.
We call these aerosols.
