Many products that we use every day -- from shampoo to antifreeze to packaged foods to electronics to textiles and building materials -- are made more durable, more lightweight, and even waterproof using a popular petrochemical called ethylene. Essentially it's everywhere. And it emits a lot of carbon dioxide into the atmosphere. 

Researchers at the University of Toronto (tip o' the cap to our Canadian friends!) have developed a process of creating ethylene without emitting the CO2, and they're using only renewable energy in the manufacturing process. 

This is a great example of keeping what's right with a product and eliminating what's wrong with it. We don't always have to do without something in order to make progress. We just have to go about it differently.
