Space Garbage


It’s been an exciting 12 months for astronomy enthusiasts – Jeff Bezos actually took Captain Kirk to outer space! But in the past we’ve jettisoned a lot of parts of our spacecraft, so how much junk is there out there? And is it a problem?

Prof. Moriba Jah of the University of Texas and Privateer is tracking the issue and discusses how it’s become difficult and why it matters.

An Engineered Earth


A lot of people advocate getting back to nature as the way to preserve the Earth but they may be wrong. Geo-engineering, in which we intervene artificially, may be more sustainable. Near Futurist Guy Clapperton asks visiting associate professor at Columbia Business School, climate economist, academic, and author Gernot Wagner and assistant professor of environment and sustainability at the University at Buffalo in Buffalo, New York, Holly Jean Buck, for their perspectives.

This is part of the Dividing Lines mini-series of Near Futurist podcasts sponsored by Diffusion PR.
