I need it bye two day

Discussion

Each week, you'll have to post on at least three separate days to the Discussion.  Each post should be of a high quality.  Your first post should be by Wednesday.

Here is the first question on the Discussion page. Be sure to select the Discussion page to the left and respond to the following question:

(5b) Perhaps investigating a sustainable city might help us to better understand sustainability. Consider the differences between the favelas (slums) of some South American cities to Curitiba. What can we learn from Curitiba about what it takes to make a city sustainable? How can we get from favela to sustainable community?
