M: what did you do over the weekend?

K: I went a global warming rally in London. It was fantastic to be around so many people who care about the environment.

M: do you think there's anything we can do to reverse the damage that's been done already?

K: it might not be possible to fix the problems that we've created for ourselves, but there are lots of things we can do to prevent more damages from happening.

M: like what?

K: well, we can use public transport instead of taking our cars for a start.

M: what else can we do to protect the environment?

K: if you do have to drive, you should make sure that your car runs on unleaded petrol. Also, your home should use sources of renewable energy.

M: how about recycling? Does that actually help?

K: yes. You should take your glass, paper, plastic, cardboard, and tin cans to a recycling center.

M: what do you think is the biggest worry for our future?

K: I think that the issue of greatest concern is having enough sources of clean water for everyone.

M: I had no idea you were such as environmentalist before!

K: to be honest, in order for the earth to continue to be a habitable place, we're all going to have to become more interested in the environment.
