World leaders at COP26 are promising to help Earth. They will end deforestation and cut methane levels by 2030. Amazon's Jeff Bezos will give $2 billion to help nature and make food more sustainable. Mr Bezos' Earth Fund is also fighting climate change. In September, it gave $1 billion to help indigenous people.
Mr Bezos decided to give the $2 billion after going into space. Looking at Earth from space changed him. He said the world looked "so fragile". He added that he did not think that going into space would change him so much. He said everyone must "stand together to protect our world" in this important year.
