The Amazon rainforest is burning at a fast rate. French President Emmanuel Macron called the record number of fires an "international crisis". He said urgent action is needed and the fires should be top of the agenda at the G7 summit of world leaders. He tweeted about how serious the fires are. He wrote: "Our house is burning. Literally. The Amazon rain forest - the lungs which produce 20% of our planet's oxygen - is on fire. It is an international crisis."
Germany's leader called the fires an "acute emergency". She said they were "shocking" and threatened Brazil and the whole world. The UK leader called the fires "heartbreaking". He said: "We stand ready to provide whatever help we can to bring them under control and help protect one of Earth's greatest wonders." The UN Secretary-General said: "We cannot afford more damage to a major source of oxygen and biodiversity. The Amazon must be protected."
