Article Details: Thousands of farmers are taking their fields out of the government’s biggest conservation program, which pays them not to cultivate.

Last fall, they took back as many acres as are in Rhode Island and Delaware combined. Environmental and hunting groups are warning that years of progress could soon be lost.

Article Details: The livestock sector generates more greenhouse gas emissions as measured in CO2 equivalent – 18 percent – than transport. And it accounts for 37 percent of all human-induced methane (23 times as warming as CO2), and 64 percent of ammonia, which contributes significantly to acid rain. And livestock use 30 percent of the earth’s entire land surface, with about 20 percent of pastures considered as degraded through overgrazing, compaction and erosion.
