Studies find microplastics in human lungs, blood stream; scientists investigating possible health risks
Scientists from the Netherlands and the U.K. recently identified microplastics deep in the lungs of some surgical patients and in the blood of anonymous donors. Researchers say that it's possible to take in these particles through the air we breathe. Leigh Shemitz, president of SoundWaters, and Paul Anastas, director of the Center for Green Chemistry at Yale University, join CBS News' Lana Zak to discuss microplastics' impact on humans and what can be done to mitigate plastic pollution. - CBS News
By 2100, we could be heading towards a loss of life in our oceans that rivals some of the largest extinction events in Earth's history if we don't continue to tackle the climate catastrophe, new modeling warns. But "it is not too late to enact the reductions in greenhouse gas emissions needed to avoid a major extinction event," Princeton geoscientists Justin Penn and Curtis Deutsch explain in their paper. Using modeling calibrated against ancient fossil records, they predict the consequences of runaway climate change on marine animals and provide a plausible explanation for an enduring ocean mystery in the process. - Science Alert
