This week, the President of the United States, Donald Trump, has broken the treatment he had with more than 100 countries about looking after the global warming.
He never believed in climate change and always despised the Paris agreement. But since he became to be President, he wanted to break this link with the rest of the world. Trump is only thinking about earning money with firms and he doesn't mind if these contaminate or not.
Many countries disagreed with his decision and they are against him. They consider it's coming back many years ago. It has been a long way since all the countries decided to do something to save the environment. This was the G7.
Today the Town Hall of Paris is with green lights to be in protest against this crazy desicion of the president of USA.
