The wants of the few compared to the needs of the many

As technology continues to advance and climate change continues to impact the global population, there is a wide gap of understanding on how our role as a society affects directly to other countries and populations. When we start talking about environmental impact at a global scale we completely ignore and undervalue the the results of our livelihood. It is very hard to grasp the consequences of the population we generate as a society as a whole and how it might be impacting poor communities in developing countries. To think that years and years of pollution has contribute to the drastic weathers we now face and the lives that it has taken over harsher storms, longer rainy seasons, hotter climates, drastically changing the ecosystems that might had started hundreds of years ago. It is a change reaction that no matter how much we try to systematically approach architecture with a more sustainable approaches we can not for see the damage we have already caused. Some people say that the most sustainable architecture is the practice of re-purposing existing buildings, finding biodegradable construction materials that require little to no carbon foot print in the making.
As many scientist have suggested we are now far past the point of sustaining the environment and instead we can only prolong the inevitable. In this extreme cases, shouldn't we be practicing and pursuing an architecture that requires zero emissions both in the construction and the life span of our buildings? shouldn't we be designing ways to construct and build out of biodegradable materials? should we be planning to design for the future of our generations to come?
