Hey, Cathy, did you read this article in the magazine? I can't believe how much man is changing the planet.Yeah, I had a look at it. Quite interesting I suppose if you believe that sort of thing.What? What do you mean,"if you believe that sort of thing"?Are you saying you don't believe that we are damaging the planet?To be honest, Mark, not really.What are you saying? Are you saying global warming isn't a fact, deforestation isn't a fact, the greenhouse effect isn't actually happening?Hey, calm down Mark. I just think too many people take these things as being definitely true without knowing all the facts.You really don't think global warming is happening.You know they've said sea levels are going to rise by quite a few meters over the next fifty to a hundred years.Weather conditions are getting worse all over the world.Can you remember how many big hurricanes there have been in this country over the last few years?I think evidence is all around us.I don't think we have enough information to be honest. We've only been measuring these things for around two or three hundred years.We have no idea what was happening 50,000 years ago.For all we know, this is just a natural blip, a kind of sudden but temporary change, in the whole climate cycle.I don't think we should change how we're living just because of twenty years of abnormal measurements.And don't you think all the other effects we're having on the planet are destructive?
