Sustainable Chemistry Terry Collins* Chemistry has an important role to play in achieving a sustainable civilization on Earth. The present economy remains utterly dependent on a massive inward flow of natural resources that includes vast amounts of nonrenewables. This is followed by a reverse flow of economically spent matter back to the ecosphere. Chemical sustainability problems are determined largely by these economy-ecosphere materials flows (see the figure‚ below)‚ which current chemistry education

If We Had Known About Green Chemistry In 1951‚ How Would Things Be Different Today? Green Chemistry is the making of chemical products that reduces or eliminates the use and production of hazardous substances in the designing‚ making‚ and use of chemical products. It involves the designing and re-designing of chemical creation and chemical products to prevent pollution which will therefore solve environmental problems. Green Chemistry is environmentally safe and has very little side effects on

How to find success in IB Biology The International Baccalaureate program offers many classes in the vast majority of SL and HL credits with the program and does so with the science section of the program. There are many different HL science classes that can be taken in IB but here at Edison‚ there are only two classes offered once you become a senior who is looking to take an HL science class. The two choices are HL Physics and HL Biology. Both are arguably the toughest IB classes offered at Edison
