Forget herd immunity... does immunity last at all?
10 min
There are several strategies when trying to control coronavirus - ranging from hard suppression to herd immunity.

The idea behind herd immunity is to let the virus spread through a population in manageable numbers with the hope that when enough recover, it won't have anywhere else to go.

But that relies on humans remaining immune.

Today: why a recent yet-to-be-peer-reviewed study has thrown more doubt on the herd immunity theory.

And Norman has some research from Nature on our good friend the D614G spike protein mutation, and why it mightn't be worth worrying about too much.

Should We Go Nuclear?
When it comes to nuclear energy, many people have strong opinions. Some say that if you're not on board with nuclear energy, then you aren't serious about addressing the climate crisis. Nuclear, after all, produces a lot of electricity and doesn't emit greenhouse gases while making energy. Others say that nuclear power tries to solve an illness with more of the disease. They say that nuclear energy, like fossil fuels, is a product of old thinking that ignores the full suite of its environmental impact - the persistence of nuclear waste, and the harm caused by mining for materials, like uranium, that power nuclear energy plants. In this week's episode, we wade into the debate. We look at the history of nuclear energy, how it became so polarized, and whether it holds the promise to get us off fossil fuels now, when we most need to. Calls to Action If you want to be part of reaching the 100% clean energy by 2035 goal for the US, there are lots of organizations working toward this. If you want to join those efforts, here are a few that you might want to consider. If you're a college student, for example, you might get involved with Environment America's 100 Renewable Campus campaign and try to push your school to go renewable.  The Sierra Club has a broader campaign called Ready For 100, to help you encourage your community to go renewable. Similarly, in Minnesota, the local 350.org Chapter has the 100% Campaign. Your local 350.org chapter may have a similar program – it's worth checking out. If you can't find a campaign near you, consider starting your own. The Climate Access Network has a toolkit on starting your own 100 percent renewable campaign (joining is required). Also, if you haven't already, subscribe to our newsletter! It’s great, we promise. You can sign up here. And if you take any of the actions we recommend, tell us about it! Send a voice message to howtosaveaplanet@spotify.com. We might use it in an upcoming episode.
