On Tuesday (2 June, 2009) three representatives, Joe, Clement, and Lauren, from S.I.F.E. - Students in Free Enterprise - visited our class and showed us a presentation PowerPoint about sustainability. They talked about social sustainability, economical sustainability, and environmental sustainability.Using an apple exemplifying the earth, they told us the fraction of land available for growing food/crops; 1/32 of the earth.
They told us about landfills, that there are 1000 closed landfills and 60 open landfills, and how long it takes for rubbish to break down:
Paper - 2.5 months
Milk carton - 5 years
Cigarette - 10 years
Tin can (tin) - 100 years
Beer can (aluminium) - 200-500 years
