The importance of organic molecules and organic chemistry can’t be overstated. It’s everything we’re about. It’s all living things but then the non-living organic chemistry well that’s the fossil fuels that we combust. So positive side of it would be that so many of the organic molecules that we've talked about like methane, ethane, propane all of these combustibles really help us to heat our homes, provide electricity—those are the positive aspects. Of course the negative aspects would be that the combustion of those fossil fuels causes enhanced greenhouse effect which could lead to global warming and things like that. Those are the negative issues that you need to actually balance in a discussion. But then what else do we do with some of these molecules in organic chemistry? Well we know that esters provide us with those types of fruit and vegetable flavorings and we can isolate those and we do and we create those fruit flavors now instead of just extracting them from the fruits and vegetables. We make them in the lab because we know how to make the esters and then we can produce all types of food products as well. What do we do with molecules of ethane? We can suck the ethane out of the ground. That is some of the things we can take out of the ground. Ethane is a gas and just like when we take methane out of the ground and clean it up and then combust it, we do the same with ethane but with ethane we take that and we make polyethylene because another way of saying ethane would be ethylene. We link these together in chemical reactions and we get plastics. Plastics were discovered back in the 1930s. Quite serendipitously too by taking these gases and making things that formed very hard, rigid types of structures and then of course we mix with the formula and made them a little softer and we get plastic bags or we get really rigid plastic that hardly ever breaks. It’s fantastic what we can do with these molecules. And we can take chlorinated ones and it was just absolutely fluke that chemists at DuPont were mixing chemicals together—there’s this one chemist, and the interface of the two chemicals when they were mixing in the solution he actually saw something form and he pulled it out. And he virtually pulled out a string from the entire solution as the interfaces came together of the two liquids—nylon. Within 6 months, they were taking nylon and only making robot of it, but finding a way to make it really attractive looking on women’s legs and nylons were created. No kidding! In six months we went from the laboratory to putting them on to your legs. Go figure!
