A sampling of New Mexico environmental leaders cites a wide range of what they consider the biggest issues for the year that was. They include Tax Increment Development Districts, the proposed Desert Rock power plant, river otters, the destruction wrought by all-terrain vehicles in national forests and a new law allowing concealed weapons in national parks. But mostly they wanted to talk politics. Like everyone else, environmentalists were consumed by the 2008 elections and the sea change coming to the Legislature, Congress and the White House.
