Last week we discussed the vast bio-region of the Amazon River, one of the most productive and important ecosystems on the planet. This week we highlight another system--the taiga--an enormous boreal forest and wetland at the top of Canada and part of the Russian federation. Both of these systems are more valuable sustained than exploited.
