ST. LOUIS (AP) — The deal reached last week by Senate Democrats would provide $20 billion for climate-friendly agricultural practices. Agriculture is a major contributor to climate change and experts say there’s plenty of opportunity to reduce the sector’s emissions. If the measures in the bill are enacted, most of the money will go through existing U.S. Department of Agriculture programs that already help farmers implement environmentally-friendly practices. The bill also funds research and efforts to improve cattle feed to reduce the amount of methane they produce. Cows are a major source of climate-warming methane.
