Do you think that the games of Jak & Daxter have a environmental message?

I was curious to know if anyone out there thought the same as me. I mean it seems that it is pretty obvious that the games do a have a environmental message. After all you do got to save the plants from dark Eco in Jak & Daxter The Precursor Legacy and Jak 3 again. Even though its a game, it seems to me like it has a environmental message. With out the plants we could not survive!
