A:Hi B, where are you going? Are you covering your face and body like a ninja?
B:Hi A! I'm going to avoid the sun. It's so hot today and there are a lot of UV rays that are harmful to your eyes and skin. Do you feel it?
A:That's right! We are facing climate change and global warming. What do you think is the cause?
B:It's probably due to human activities, right? Burning fossil fuels releases a lot of CO2. What do you think about this?
A:Exactly! CO2 acts as a greenhouse gas, trapping the sun's heat on the Earth, making us hotter. So what do you think we should do to limit climate change?
B:I think we should reduce cutting down trees and burning forests, and switch to using renewable energy such as solar, wind or hydropower. Do you agree?
A:I totally agree! Factories should also reduce their emissions into the air.
B:Yes, and if we don't act now, things will get worse.
A:Sure! It was great talking to you. See you later!
B:Bye A
