On this week's Earth Beat: one major criticism of the meat industry is the amount of space it takes up - cattle need fields to roam around in and there simply isn’t enough room for them.

The solution? Well if you can’t expand the land, why not shrink the cows? Professor Richard Gradwohld breeds ‘Teacup' cattle which he claims provide more beef, on less space. The cows are old European breeds - which used to be much smaller - and eat grass, as opposed to corn. So not only are they healthier, says Prof Gradwohld, they taste better too.
 
Earth Beat reporter Martha Baskin went along to meet him at Happy Mountain Farm, just outside Seattle.
