Okay. My mind is been wondering too and that can be a dangerous thing.
Perhaps the opportunity at Epcot is get past what "man has done" on "Spaceship Earth" and look deeper into the planet itself and what truly sustains us? To show the resiliency of the environment gives us hope that the planet will always be here if we are, it's up to us to behave in a way that allows us to be a worthy tenant. It seems the Gulf of Mexico is healing itself faster than some expected. When forest fires doomed Yellowstone Park in the 80s everyone thought it was lost forever until the earth brought it back in a different yet beautiful way. For the first time in human history man seems to feel like he is truly at the mercy of the planet itself and fears for his extinction. Ironically we know so little about our planet but can't wait to get off of it and settle another. Perhaps part of Epcot's mission could be to use landscaping as an attraction to help to future generations to really understand our home better. Imagine what the Land Pavilion could be like if you let landscape architects and designers go crazy. Like a rock star that trashes a hotel room, man needs to be a better guest. The earth could show you how. When Epcot opened no one would've predicted that, other than pollution we would have been faced with any kind of global climatic issues to try and understand. As you've pointed out, Epcot Center showcases the wonders of nature in a unique way. Can we go further?
Of course, the one thing you could say about the 21st century is that more of man's problems are global and no longer regional. Epcot being a park steeped in the notion of international cooperation, would have been a perfect showcase for positive global solutions to man's problems. But no matter what you do, it becomes political at some point. Even the subject of environment which used to be a very benign topic, is now a gigantic industry so it has become politically charged as well. In absence of that, it's probably not a bad idea to at least humbly admit that we
know that we don't know, but are willing to learn. Of course, you teach a better way by kindling people's curiosity about what can be, and being a living example. They can decide if they like it or not. "We are doing" rather than "You should be doing".
I can tell you that when it comes to landscaping I have a renewed sense of discovery and appreciation for the miracle that the Earth truly is and how to better showcase what's already here. All I'm really saying is that the earth itself plays a crucial role in our future, and to your point, Epcot is a perfect place to draw attention to that.
All over the map here, thanks for being patient..
