Ways to Fight Food Waste

1.3 billion tons of food is discarded each year, while an estimated 795 million people are undernourished. “Most European and North American countries already have between 150 and 200 percent of the nutritional requirements of their populations,”

food waste affects far more than our garbage cans, wallets or stores; it squanders our limited resources of water, energy and land. If wasted food were a country, it would be the third largest emitter of greenhouse gases in the world, consume $2.6 trillion a year, and occupy nearly 30 percent of the planet’s farmable land, according to a report from the UN’s Food and Agriculture Organization

Science in Service to the Public Good

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.

Ways Society can avoid a Catastrophic Drought

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.
