People meet in Brazil. They talk about our Earth. It is a big meeting.
Many people are sad. They do not think things change. It is hard to make change.
The world needs new power. Companies like cheap power. This makes Earth help slow.
Some people stop rights. This makes Earth help hard. It is not good for us.
We still need old fuels. This makes Earth warm. We need clean power now.
Some countries have good ideas. Spain will build cool places. This helps in hot days.
But rights are in danger. Some groups hurt women. This is bad for girls.
China wants more babies. They help mothers and babies. But they make rules strange.
The future is not clear. We need to help Earth. We need to help people.
