Now that we've analyzed the problem itself, we can begin to evaluate the solutions involved (or lack thereof). Not all answers are equal in terms of overall benefit to social, environmental, or economical factors. First, we'll explain each one in depth, and potentially ones that aren't being used but probably should be. Then we'll analyze their effectiveness based on varying criteria. Finally we'll assess alternate solutions that may exist but haven't been brought into the contemporary sphere. Many of these supposed solutions may be dependent on the intent of the individual, and thus relative in terms of effectiveness. By no means is this a definitive list; there are undoubtedly many more answers to these environmental questions than we even have the capacity to describe, given our somewhat limited knowledge on the subject.
