Podcast 128 - Conservation Paleoecology

The gang talks about conservation paleoecology; the study of the fossil record to inform modern conservation efforts. Specifically, they look at two papers, one which is an overview of the current issues in the field, and the other which focuses on how mass extinctions can change the distribution of species on the planet. Also, James has very strong opinions about the most recent Splatoon 2 Splatfest, Amanda nearly breaks an arm, and Curt tries in vain to hold everything together.

 

Up-Goer Five (Curt Edition):

The friends talk about how life is dying. A lot of people think life is dying faster than we think it should and that people might be causing life to die faster. The friends talk about how we can use the past to see how quickly life died in the past in order to let us know if the dying we see right now is a problem. There are a lot of people who have looked at the past and they find that people have changed the land and water and air a great deal. These changes do seem to have helped make life die faster. But there are things we can try to do to try and stop this, and keep more life in the land, water, and air. And we can use the past to understand what land, water, or air we should put the most work behind to really stop life from dying so quickly.

The friends then talk about a time when a lot of life died at once. At this time, a big change happened in the air, land, and water. At that time, most animals in the land, water, and air died off, but some animals did really well. They seemed to like the changes and moved all around. These animals that moved all around might have changed how life gets better after dying a lot. This suggests that animals moving all around might be something we see during times when big changes in the land, air, and water cause life to start dying really fast.
