Scholars’ Circle – Predatory Humans affect ecology -/- Current Problems with Health care delivery – October 15, 2017

First, is humanity the most damaging predator on earth? Our guests say yes, and that its predatory practices may be disrupting evolution. [ dur: 23mins. ]

  • Chris Darimont, is a Professor at the Department of Geography at University of Victoria, Victoria, BC. He has a PhD in Evolution and Ecology from the Biology Department at the University of Victoria.
  • Dr. Tom Reimchen, is a Professor at the Department of Geography at University of Victoria, Victoria, BC. Canada. Please visit the Evolutionary Studies Lab at University of Victoria, Victoria BC, Canada where you will find additional studies on this subject.
  • Heather Bryan is a postdoctoral fellow in the Applied Conservation Science lab at the University of Victoria BC, Canada. She studies the physiological mechanisms by which wildlife responds to environmental change.

Together they are the authors of the research paper The unique ecology of human predators you can view on the Science site.

Then, on the Scholars’ Circle panel, many observers argue, that the economic forces are corrupting medical care and eroding the trust between patients and their doctors. The problems in health care delivery have wide implications related to how health care should function particularly when there are limited resources. We examine the ethics of medicine and healthcare, and the modern day issues that complicate them.[ dur: 37 mins. ]

Scholars’ Circle – Tipping points of Eco-Systems and Climate – October 1, 2017

We spent the hour looking at the science of tippings and what they mean for our climate and our ecosystems on land and in water today. What causes these types of sudden changes? And how can society be better prepared for such events? We spoke with three scientists whose studies involve tipping points, how they happen and their effects.[ dur: 58mins. ]
