In January 1970, the organizers of the first Earth Day published a full-page ad in The New York Times. A few months ahead of thousands of demonstrations and teach-ins across the United States, they declared that Earth Day represented “a commitment to make life better,” “to provide real rather than rhetorical solutions,” and “to challenge the corporate and government leaders who promise change, but who short change the necessary programs.” They continued, “April 22 seeks a future.” Ad Policy Each week we cross-post an excerpt from Katrina vanden Heuvel’s column at the WashingtonPost.com.

As the Post reported last month, the proposal would slash roughly a fifth of NIH’s funding in fiscal year 2018, “a seismic disruption in government-funded medical and scientific research.” The administration has also proposed a separate $1.2 billion reduction in the remainder of this year’s NIH funding, along with severe cuts to the National Science Foundation, the Environmental Protection Agency, and other programs, to pay for a border wall and higher defense spending.
