Skim the paragraph and write what the main idea is.
For most people, watching mega sports events such as the Olympic Games is an enjoyable activity. Millions of people sit in tront of their TVs every four years, and countries are very keen to become the hosts of the Games, However, all this fun has consequences for the environment, and they aren't fun at all. Mountains of itter are produced at big sporting events, from plastic bottles to plates, from packaging to food waste and tons of paper. An enormous amount of resources is needed to build the stadiums and the places where athletes, officials and journalists live during the event. And all those thousands of people need to travel from tfar away t's no secret that this causes air pollution.
Can you write as short as posible. Thank you
