Sustainability
As human beings we take our environment for granted. Society in general believes that the earth is so large that it can contain and deal with our species short comings. Obviously we were wrong. I don't want to get into global warming and all that jazz, because i feel as if that topic has been beat to death. So lets talk about oil:

The above figure illustrates oil production in the world. What happens when we reach the peak? There is going to be an oil crisis (period). Lets take a look at oil discovery:

As you can see, oil discovery has become less and less. We are finding less and less oil because we are good at finding it. We have found the large quantities out there, but there are only small fields left. After we stop finding new ones and others go dry there will be no more oil to drill for. Then what? Alternative energy sources? What about public transportation? Or just TRANSPORTATION!?? What are we going to do? There isn't much time, supposedly there will be a crisis within 20-30 years. Can we design and engineer other ways of transporting a nation?
Transportation is not the only issue that we will run into when the oil runs dry. Look at any man made object and there is a very good likelihood that it was built from petroleum products. The computer you are viewing this page from is made of 90% plastic which is an product of oil. Your car is mainly plastic, most containers are plastic, you entire environment is surrounded by oil products.
So i leave you with a thought, what can you do to reduce your dependency on oil? Condition yourself, because the end is near!
