Experts say most of these fires were set by farmers. The farmers were attempting to clear land to grow crops. The World Wildlife Fund says another serious problem is that too many trees in the Amazon rain forest are being cut down. World Wildlife Fund says the fires show the need for urgent international action to protect the world's rain forests. The group warns that without such action some forests could be lost forever.

● Don't leave the kettle to boil away. And don't fill it to the brim for only a cup of tea!
