Well on my last day in the wonderful town of Tuscon Arizona I had the opportunity to go to the Biosphere 2 complex. Now that was a very fascinating place to go to. It is there where they built a ninety foot tall sealed self contained ecosystem which covered 3 acres of land. It supported 3 men and 3 women for 2 years, all for the name of Science.
Built in 1991 they put the scientist in and sealed them off from the rest of the world for a period of two years. As the next few photos will show, Biosphere 2 had many different climates ranging from a rain forest
to the severe desert climate. 
As I was able to tour inside the Bio-sphere I was able to feel the change in enviroment as I walked from area to area.
They even had an artificial ocean which is the largest ocean in the world that is above sea level. 750,000 gallons, how cool is that. I beleive they said that the depth ranges from 24 feet at the deepest end and of course goes back to a beach looking area, but in between there in the middle it ends up like a reef kind of and comes to the surface and then back to a depth of 12 feet and back to the surface at the beach. I would love to have one of these in my back yard. Talk about a bunch of maintance though. That is a lot of water, and get this it was even made out of homade sea water out of Insant ocean salt for salt water aquariums.
Although I realize I will likely never have my own aquarium salt water tank this big, I will have one that is a bit smaller. I am looking forward to it very much actually. Oh and it will be a saltwater reef tank :)
One of the things that they stressed about Biosphere 2 was that it was made so that they could 1 see if they could survive in a self contained basically container, and 2 it was an area where they could control the enviroment in its entireity. Ranging from how much rain the plants got to the temperature of the air. I was able to learn so much about the earth, and what actually makes the earth a biosphere and just how fragile it is, and what we can do to help the earth sustain us. Isnt learning the great!! I am so happy my brother told me to go, just wish he was able to go with me!
It was a great trip and I had a lot of fun.
