Chemistry

I need help finding reactions beneficial to society. Here's the assignment quoted.

"Your assignment is to research two different chemical reactions that are used to address social/environmental needs or problems. These reactions must clearly be attempting to improve our world. Ex. A scubber reaction is used to reduce or eliminate air pollution by removing or neutralizing exhaust gases. (This example cannot be used). The key is that you must be able to identify the chemical reaction and demonstrate that it has clear benefits to society/environment and addresses an existing problem or issue."

  1. The scrubber reaction would have been a great one to use; however, that is out. So what about a different kind of scrubber (which isn't called a scrubber)? I think you could pick the reactions in the exhaust pipe of an automobile and how the catalyst removes NOx and SOx gases. That is an environmental problem. Look on the web and see if you can find enough information about the catalysts used and how they work.
    Would the reactions going on in an air-bag inflation system on an auto be a society problem (it keeps people from dying in an accident which seems to me to be a part of society). You be the judge. Keep these two in mind while you whirl your brain cells around a little. You may be able to think of some, now that I have teased you into the right path, that are better.
