Remaking Nature
Carl Zimmer has a provocative story in Yale 360 that questions some conventional wisdom on exotic species. Alan Burdick’s terrific 2005 book tread similar ground.
As I see it, anything that enlarges our understanding of nature and our role in shaping it (as urban ecology has done in recent years), is a good thing.
Great Q&A on exactly this subject in last month’s Scientific American:
