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.
