Because we were prepared for the downturn and the "bear market bounce" today we were not caught up in the market frenzy and continue to delve deeper into what truly are the best practices for sustainable investing...In our research today the question of supporting bio degradable food based plastics came up.. if we are using petrochemicals to grow the food for plastic we take up land for food and use petrochemicals at the same time…the key may be the relative environmental footprint including the plastic waste vs bio-degradable waste, and the amount of land required for the bio-plastic. It gets even more complex: is the starch used for making bio-plastic a by product of food production? If so then much less land is being given up and the agricultural footprint gets smaller. My gut tells me that bioplastic is much more positive than biodiesel all things considered and that we should support its development. Just think of the mountains of plastic bottles (I will never forget the masses of them in the Urubamba River in Peru!) that would melt in time like sugar back to the earth…
