Vice President Kamala Harris has garnered more than enough delegates for the Democratic nomination for President. We review her record on the environment, which has included prosecuting cases against polluting oil companies, supporting a Green New Deal, and representing the US at UN climate meetings.

Also, the four years of the Trump Administration brought over a hundred regulatory rollbacks, the exit of the US from the Paris Climate Agreement, and a conservative dominated Supreme Court that is skeptical of environmental regulation. We hear insights from a former Trump EPA official, environmental policy experts and advocates about the environmental impacts of the Trump presidency and what a second one could bring. 

Plus: a scientist who rappels down cliffs to hand-pollinate endangered plants; a vine that mimics the leaves of nearby species; rice that crowds out strangers but leaves room for the roots of relatives. All of these are featured in the new book The Light Eaters, which tackles big questions of plant intelligence, consciousness, and communication.
