To help resolve the current environmental issues, austerity policies should be imposed on all countries without discrimination, and perhaps this should be accompanied with economic aid to poorer countries to help solve a more than likely disagreement that may come about with its proposal. However, there is no sign that such project will ever be carried-out, not even a considerable effort toward this, given the current political environment our representatives must cope with daily. It is not of light importance to the welfare of future generations, and perhaps even to our survival, it is crucial that such a development be made toward a greener future. There is not a single person who can ignore the importance the environment has, from the most careless of individual to the most caring, and for that very reason we must all strive toward protecting it, I argue. For those who are careless, scarcely could they have known ill from pollution if they do not simply lack empathy, be it physical or moral; and as for the latter, they probably do not lack in either of these, be it empathy or knowledge; for that, by their opposition they lie at the opposite ends of the spectrum; however may that be, both know the importance of the safeguard of the environment and both therefore should not be exempt to contributing as much as they reasonably can. We all must practice austerity; for instance, electricity must be considered as a luxury, against to great indulgence in which everyone should be warned.
