The six-part series of short documentary films entitled “Let Science Speak” was made in direct response to escalating efforts to suppress environmental science and silence scientists. “More than anything, this series is about not only science and why science matters, but who we are as scientists,” Dr. Dawn Wright, one of the scientists featured in “Let Science Speak,” told Kara Howland of the blog TV Goodness. “Some of us are parents, some of us are people of faith, we’re all people who care about our communities.” On Tuesday’s “Leonard Lopate at Large,” join Dr. Wright along with series creator Christine Arena for a discussion of why science matters.
