Three Reasons Congress Should Support a Budget Increase for Organic Agriculture Research

Recent headlines about the US Department of Agriculture’s leadership and scientific integrity have been unsettling, as have indications that the Trump administration intends to slash budgets for agriculture and climate research and science more generally. But today there’s a rare piece of good news: a bipartisan trio in Congress has introduced legislation that would benefit just about everyone—farmers and eaters, scientists and food system stakeholders, rural and urban Americans.
