They believe that people, as individuals or working cooperatively together, can change most aspects of the physical and social environment if they decide to do so, make appropriate plans, and get to work.
My interpretation is:
they can change it, if they decide, make plans and get to work. (i.e the condition to change it is their decision, plans and actual work)
But the book I have says its:
they can change it, make plans and get to work, if they decide to do so.
Now, which interpretation do you native speakers think is correct?

Your interpretation is the way I understand it.
