Will we lose 1/5 of all our plants?

It certainly seems possible, with 22 % of wild plants on the endangered list (along wiht 21% of mammals and 12% of birds).

A lot of the problem is down to the clearing of the rain forests.

If all the plants vanish, so will all animals and birds. – Eimear Nic Lughadha, Royal Botanic Gardens, Kew, London
