Even those who are not interested in climate change and in the well-being of the environment usually know that using inefficient light bulbs rather than efficient ones, eating meat rather than vegetables and traveling by car rather than by public transportation result in higher greenhouse gas (GHG) emissions. What they probably do not know is that if you live in a Western country, many of the simple daily actions you do are a major source of emissions. What if I told you that the Western lifestyle is highly unsustainable?
