Long Island environmentalists are calling Brookhaven Supervisor Brian Foley a "liar" and a "tree hater" Monday. Members of the Long Island Environmental Voters Forum are apologizing for endorsing Foley in 2005. They claim he broke his promises to the environmental groups that helped him get elected. Now, they are calling him a threat to the environment, the economy and the quality of life in Long Island's largest town.Foley says the accusations are without basis. In an afternoon press conference, Foley used a dozen visual aids to tout his environmental accomplishments. Foley says his administration has purchased and preserved more land in his first year in office than any of his predecessors.
