SUSD0003 Week 1: My ecological footprint

After taking the WWF footprint calculator and hearing through the first lecture introducing the concept of sustainability I realise that I am part of the problem that contributes to the current climate change crisis.
With my lifestyle, even as a thrifty student, I need approximately 3.4 Earths in order to sustain it. Even after I make the pledge to half the amount of meat products I consume I still need 2.7 Earths as the screenshot shows:

I often get the ideas and motivations that as an architect I have the power to change the world. But what is the point of that if I cannot change myself. The concept that design can fix or at least lessen climate change is not completely delusional, it just needs a lot of work and perhaps a new way of thinking.
But first, I realise that I have to change myself first to even stand a remote chance of changing the world.
