“When we are able to grow the resources we need,
we will finally be on the road to sustainability”
-Gurinder Shahi-
It probably took me a while to digest that prof is quoting himself but i guess it is good quote indeed. Initially,I believe that to be sustainable, we have to present everything in a closed loop such that materials can recycled in an endless loop. I guess as long as we are able to grow or create what we need and there's proper management of waste, we can create a sustainable system whereby, injection into the system equals the removal of waste from the system. As long as this injection is purely derived from products that do not consume non-renewable resources, this system is sustainable.
I posted a question in class, after reading Reading 1 about how much arable land do we require. Eventually, I found out through http://ask.metafilter.com/77287/How-much-land-does-a-person-need that the minimum is a mere 0.7 hectare if we consume the most efficient crops and 5.0 hectare if we live an average American lifestyle. Also, from reading 1, it is known that arable land had been reduced to 2.2 hectare per person worldwide now. It is now clear that we do not have enough land for everyone to live an American lifestyle. On one side, we should encourage American to adapt their lifestyle and on another hand, invest in agribiology to maximise our output for our arable land and perhaps, learn to grow food in a lab, which could greatly increase human's food production. It would be simply unfair and a white man supremacy in the act if we ask the developing nations to not consume the way we do. Anyway, short post it shall be, for the research paper is due soon -.-
