So we're not going to replenish petroleum, but we can grow crops from which we can isolate useful components. So we can grow corn, we can grow canola from where we can extract oils, and those oils can be used as fuel. Those would then be termed as bio-based. That is certainly a legitimate endeavor. For example, we are already doing that to some extent.

For example, we are already doing that to some extent.

As you may know, gasoline can have up to 10% ethanol content. And that ethanol can come from corn because the glucose in corn can be fermented to produce alcohol. So that would be biofuel. And then, of course, we also talk about biodegradable substances. And that is also a very important concept in terms of environmentalism.

because we don't want substances building up in the environment that will stay there forever. We would like them to decompose into innocuous substances. So there's a lot of work on that as well, especially when it comes to plastics. Plastics have been demonized recently. And there's, of course, some legitimacy to that.

We don't like to see plastic bags fluttering in the breeze or hanging in trees. We don't want to hear about this giant plastic garbage patch in the middle of the Pacific Ocean. We don't want to hear about nanoplastics, which are the end product of the badgering by sunlight and waves of plastics that get into the ocean and which eventually end up in our body, right?

We don't want micro nanoplastics ending up in our body. So the question is to produce substances that are biodegradable, meaning that they will break down. And we can do that with certain plastics. Polylactic acid, for example, is made from corn, and it is biodegradable. However, there's a but. There always is a but in science. We tend to give with one arm and take away with the other.

So it would be great to have the one-armed scientist who only gives us good things. The fact is that these biodegradable plastics are biodegradable under ideal conditions, which usually means some sort of industrial, commercial composting facility.

And I can tell you that I've done an experiment where I have one of these plastic cups, the polylactic acid cups that are biodegradable, and I've left it out in my backyard and now for two years. And I can tell you that it has not degraded at all. It looks the same as it looked then.
