Very good,To learn about sustainability and impacting the environment positively,The old dude is cool,It would be nice if I didn't have to keep logging in. Other than that: it's easy to navigate - good site,The transfer of knowledge is great. There is so much beneficial content. ,I would like to be able to get hard copies of the lessons. My bandwidth is sketchy and I find Vimeo to be temperamental. ,I don't think it interests me that much as I'm after knowledge - not accolades. ,This is a great course for anyone who's interested in being part of the solution to the problems this generation has created regarding the environment. ,Good work.
