One of the richest countries in the world are refusing to fight climate change. Saudi Arabia. The reason they are refusing to do anything is that they have an oil business which is worth 1,900,000,000 Saudi riyal ($500,000,000USD) . As you probably know, oil is worth a lot of money right now but it is very bad for the environment. So in conclusion, the country that can do the most to fight climate change is doing the least. This means that other countries around the world are having to do more and more to make up for Saudi Arabias poor efforts.
