Personal space

The stuff in the news today about the astronaut is very strange and sad. Even more upsetting was the article I saw about the space trash that just randomly floats about orbiting the Earth, quietly meandering through space.

This article is pretty sad too - toxic ammonia that leaked during the recent spacewalk.

I wonder why more people aren't alarmed by this - especially with all the media attention lately blaming humans for global warming. Aren't we ruining space as well?
