US trees being used for fuel in the UK

Forests of trees in the US are being chopped down and brought to the UK to burn in UK power stations for energy.

It's happening because of rules set by the European Union to increase energy made from renewable sources, in order to combat climate change.

But conservationists say this is a waste of money and wrecking forests.

In areas like the South East of America, there are plantation forests where trees are mainly grown for building materials.
