You've probably heard this one before: Plastic is made from oil, and oil is made from dinosaurs, so a plastic dinosaur is made out of real dinosaur. It sounds pretty profound... but it's not that simple.

Well, it wouldn't be too long after we started developing Ecology that we would try to control the environment. In some ways this was helpful and likely prevented a lot of people from starving. But, there have been a few downsides.

We’ve explored the origins of modern biology, the earth sciences, and even the sciences of outer space. Now it’s time to put these disciplines together. It's Ecology time!!!
