I remember watching a movie between the years 2007 and 2011. I am pretty sure it was an anime because it was animated.
I remember a futuristic setting with the planet earth in ruins. The main character was a girl and I think I remember deaths (as in people died) :3 but it couldn't have been anything extreme since I was around 11-14 years old and had never watched anime at that point and would have been turned off by that.
I remember something about a last plant or a spirit that the main character had to collect and maybe the earth having radiation or disease that needed her to wear a special suit, and I also remember her having to go through a test when she got back to base which was some ship to test her for this disease or thing.
I also remember a guy failing this test and some people at the end trying to get to a vehicle like a truck with an open top but that is about it.
Thanks in advance.
