Brad: Hey, Jamie! Did you watch the documentary about Environmental Science? It was very interesting.

Jamie: Yes, I did. It surprised me how complicated it is to study and analyze air pollution.

Brad: Exactly, I didn’t imagine all that, but particles are too small to be easily seen.

Jamie: Did you see when they started to explain different projects using renewable sources to reduce pollution?

Brad: Yes, the one about water pollution was particularly interesting.

Jamie: I know, water is a very important element for our surviving. We need to take care of it.

Brad: You’re right, I made some research on the internet and I found that a lot of sciences are involved in this area. Physics and Chemistry are the most important.

Jamie: Wow! Then all those investigators must be very hardworking.

Brad: They are. I could see that they know what they do when starting a research.

Jamie: That’s admirable! Did you see the project about reducing air pollution because of factories?

Brad: No, I didn’t. I got a little distracted. Was it good?

Jamie: It was excellent, you should watch it again and see. They said that it is urgent to reduce the negative effects on the planet.

Brad: Absolutely, thanks for telling me. I learnt a lot with the documentary. Did you?

Jamie: Me too! Let’s go find more information online.

Brad: Sure, let’s go! Maybe I could be an environmental scientist.
