Video Transcript:

If something is renewable, it essentially can be used over and over and over again.  That doesn’t mean used over for the same purpose, and if we’re talking about ecosystems that are present in any given setting, the materials that are present in that ecosystem renew themselves by being used by many different organisms.  By the same token, when we talk about what people are doing, if we start looking to systems that are renewable rather than systems that take resources out of the ground, use them for a particular purpose and then are thrown away as trash, which isn’t useable, that’s non-renewable.  Whereas, if we make use of resources and the type of resources that literally can be made from one thing into another thing into another thing and so on, then we’re starting to get to renewable.  And this is what we need to do in order to protect the abundance and the health of earth and ourselves.  We won’t live long on this planet if we are, you know, literally trashing the place out and then trying to live in our own toxins and trash.
