A while back a friend, Jazz, and I conjured up a business idea that dealt with renting textbooks rather than buying, so it would be cheaper and more environmentally friendly. After getting into the nitty gritty of the proposal, we dropped it and the idea quickly withered away.
Apparently, when it withered from our minds, the idea traveled to the people behind the website Chegg.com.
Chegg.com is a textbook rental website that has over a million textbooks that you can rent for an allotted time- semester, quarter, or intersession. The shorter the session is, the cheaper it is. Chegg gives you ample time to return books and it covers shipping when returning them. You can also sell or donate books!
The most splendid part of this whole idea is that for every text you rent, sell or donate, Chegg will plant a tree! So not only are you reusing textbooks, which decreases their demand, so less texts are printed but you're also planting a tree simulatenously. Granted, you do waste material on packaging BUT most of us buy our books using half.com or amazon anyway, so wastage already occurs. At least with Chegg, books come from the same place rather than different locations, so all the books rented are packaged in one box.
We are and have been in an age when forests are infinitely stripped down and their slaughtered bodies aren't even fully utilized. Chegg is an efficient way to decrease your contribution in this cycle of greed.
All-in-all, Chegg is economical + environmentally friendly= SuperGreen!
