We give scientists and engineers great technical training, but we’re not as good at teaching ethical decision-making or building character. Take, for example, the environmental crisis that recently unfolded in Flint, Michigan — and the professionals there who did nothing to fix it. Siddhartha Roy helped prove that Flint’s water was contaminated, and he tells a story of science in service to the public good, calling on the next generation of scientists and engineers to dedicate their work to protecting people and the planet.
Can the chemicals that plants and trees give off be good for your health? Yes, say forest bathers, who are immersing themselves in nature to combat stress.
As the world’s climate patterns continue to shift unpredictably, places where drinking water was once abundant may soon find reservoirs dry and groundwater aquifers depleted. In this talk, civil and environmental engineer David Sedlak shares four practical solutions to the ongoing urban water crisis. His goal: to shift our water supply towards new, local sources of water and create a system that is capable of withstanding any of the challenges climate change may throw at us in the coming years.

Plastics are overwhelming our oceans and landfills. Every year, an estimated 19 billion pounds of plastic garbage end up in the sea. In the U.S. alone, approximately 56 billion pounds of plastic are dumped annually in landfills.
But here’s a heartening truth: We can all do something to mitigate this growing plastics crisis. Yes, all. From entrepreneurs and corporations who need to rethink the way plastic products are designed and manufactured; to lawmakers who can push for the protection of fragile environments from plastic pollution; to individuals (that means you) whose seemingly small daily actions can add up to something huge, we all have a role to play.
In general, less than 7 percent of all the plastic that Americans throw away each year are recycled, and about 8 percent are combusted in waste-to-energy facilities. The rest end up in landfills.
An average American family of four uses more than 1,500 plastic bags every year, according to the NRDC. Each bag is typically only used for about 12 minutes; yet since plastic bags are very rarely recycled, most of them end up in landfills, where they can languish for hundreds of years.
This animated map created from the NOAA, NWS, and PTWC shows every recorded earthquake in chronological order from January 1, 2001 to December 31, 2015. The size of the circle shows the magnitude of the earthquakes in relation to each other. The color represents the earthquake depth.
