When humans hunt and fish, they tend to favor animals that provide significant resources. In the oceans, whales, sharks and other large vertebrates have been targeted for centuries, and while the international ban on whaling has helped some species recover in select areas, many populations have fallen to a fraction of their natural levels.

Information communication technology (ICT) such as computers and cell phones has proliferated throughout the world, and many developing nations are consuming them at an increasing rate. Moreover, as such goods become technologically outdated in wealthier nations, they are often shipped to developing countries for refurbishment, recycling or disposal. However, such countries are sometimes ill-equipped to deal with the parts found in many products in an ecologically sound manner.

Reporting on the issue of climate change has sometimes been characterized by “false balance” — the tendency to cover scientific findings as if there were always two “sides” that each legitimately differed over facts. But over the past decade, the scientific consensus has grown even clearer: Global warming is happening and humans are the cause.
