Two Earthy Investments for Earth Day

In honor of Earth Day, we looked at a few companies dealing specifically in earth, lots of it. Rio Tinto (ASX: RIO) and BHP Billiton Limited (ASX: BHP) are the largest diversified mining and resources companies in the world.

While we can’t talk about their environmental impacts, which may or may not be great, we can look at their place in the global markets and the commodities cycle. It’s no surprise that they are stable barometers of the economic health of the world economy.
