Save the Rainforests?

I just got the following message on a dating website:

Your face would save the rainforest.

What does that even mean?  I assume it's a compliment, but I'm not 100% sure.  My face would inspire people to make more environmentally sound decisions?

Or, is it maybe an insult, but maybe I'm just some stupid self-centered girl who'll assume it's a compliment and say 'thanks!'

Although he doesn't look like the kind of guy I'd be interested in, or seem to have much in common with me, I kind of wanted to reply, just saying 'what does this even mean?', but I was advised by a good friend that 'this is his trap.'

Your thoughts?  Anyone else receive a really strange compliment?  Anyone know what this means?
