The Climate Change Denier Acid Rain Argument

Many lakes in northeastern America at dead in the 1980s had plenty of fish in 1900. It was surmised by environmentalists that 20th century sulfur dioxide emissions had choked these lakes to death with acid rain. But studies show they were acidic and fishless even before European settlement. Fish survived better in these lakes around 1900 because of extensive slash and burn logging in the area.
