Many of these ecosystem services have been ruined due to our presence of the planner. They are rather optimistic, many are convinced that we will come up with some science or technology to fix it.

Assessed in terms of the problems of inputs and the problems of outputs. Natural resources -resource use-> materials and fuels in use -emissions-> wastes in the environment. Inputs that we extract, get something that is useful, have some emissions leftover.
