Green rooftops are certainly a very unusual concept. While I like the idea of using grass instead of something else, I sure wouldn't want to be the one that has to mow the grass...

This is the first time I have seen anything about this. I find this interesting and glad to see Toyota being a part of it. I agree with you about the mowing aspect of it though.

I never heard anything about this before either! And interesting concept! I don't know if Toyota being part of it is a factor, but I am intersting to see what happens over time...

it's a great idea in theory... but i don't fancy getting up on the roof to mow the grass 'only once a month'..

but green points to Toyota for making the effort... now if only we could talk the rest of the world corporations into doing the same...
