The story

A new report on the state of the world's plants says that more than 2,000 new species were discovered last year alone including a three-metre-tall orchid and a sprawling insect-eating sundew plant from Brazil.

But the researchers from the Royal Botanic Gardens in London warned that a fifth of all plants were at risk of extinction – vulnerable to climate change, habitat loss or disease.

We have a huge demand for food, so there's a lot of mouths to feed in the world now and that's growing. And we need the land, so basically the natural habitat is being converted so that we can have soya plantations, crops, livestock and as a result that's really causing species to lose their habitat and get closer towards extinction.
