October 10, 2018 Sustainable Whaling?
https://earthwiseradio.org/wp-content/uploads/2018/10/EW-10-10-18-Sustainable-Whaling.mp3
The hunting of whales in the 19th and 20th Century nearly drove the giant mammals to extinction. By the 1960s, improved hunting methods and factory ships made it clear that whaling could not continue unchecked.

October 09, 2018 Reducing Food Waste
https://earthwiseradio.org/wp-content/uploads/2018/09/EW-10-09-18-Reducing-Food-Waste.mp3
Food waste is a huge problem. About a third of all food produced globally goes to waste, and the numbers are even worse in the US. If food waste was a country, it would be the world’s third largest emitter of greenhouse gases. Worse yet, all of this takes place in a world where 850 million people are chronically undernourished.

October 08, 2018 Earthquakes And Injection Wells
https://earthwiseradio.org/wp-content/uploads/2018/10/EW-10-08-18-Earthquakes-and-Injection-Wells.mp3
The expanded use of injection wells and fracking has brought about a significant increase in earthquakes in places that didn’t have very many before. Wastewater injection in Oklahoma increased earthquake totals from dozens per year to over 900 in 2015 before collapsing oil prices reduced the use of the technique. Increased earthquakes in Alberta, Canada were triggered by fracking in that area.

October 05, 2018 The Famous 97%

One still hears reference to “the debate on global warming”. Is there really a debate? Certainly, there are people who want to think there is, especially those with a vested interest in not doing anything about it.

October 04, 2018 Cleaning Up Storm Water
https://earthwiseradio.org/wp-content/uploads/2018/09/EW-10-04-18-Cleaning-Up-Storm-Water.mp3
Storm water reclamation is an important activity for cities with limited water resources, such as those in Southern California. Many places have small-scale reclamation efforts using rain gardens and bioswales. Collecting storm water on a large scale faces a number of problems.

October 03, 2018 Using The Sun To Remove Ice
https://earthwiseradio.org/wp-content/uploads/2018/09/EW-10-03-18-Using-the-Sun-to-Remove-Ice.mp3
Ice buildup can cause all sorts of problems ranging from performance issues to catastrophic failures. For example, ice buildup can negatively impact things like airplanes, power lines, wind turbines, and the like. Preventing this ice buildup typically requires energy-intensive heating systems or environmentally-harmful chemical sprays.

October 02, 2018 Better Sell-By Dates For Milk
https://earthwiseradio.org/wp-content/uploads/2018/10/EW-10-02-18-Better-Sell-By-Dates.mp3
The sell-by and best-by dates on milk cartons are ones we tend to pay close attention to. Many of us automatically discard milk if it is past one of those dates. However, those dates are not really scientifically established but rather are guesses based on experience.

October 01, 2018 Pests And Crops In A Warming World
https://earthwiseradio.org/wp-content/uploads/2018/09/EW-10-01-18-Pests-and-Crops-in-Warming-World.mp3
By the year 2050, scientists predict that there will be two billion more people to feed in the world. And climate change isn’t making that task any simpler. From extreme weather events to rising global temperatures, climate change is expected to affect the types of food we grow, and to negatively affect the food production needed to feed the growing population.

September 28, 2018 The Return Of The Bison
https://earthwiseradio.org/wp-content/uploads/2018/09/EW-09-28-18-The-Return-of-the-Bison.mp3
At one time there were 20 to 30 million bison in North America, dominating the landscape from the Appalachians to the Rockies, and from the Gulf Coast to Alaska. A combination of habitat loss and totally unregulated hunting of the huge animals reduced the population to just over 1,000 in 1889.

September 27, 2018 Energy Justice In California
https://earthwiseradio.org/wp-content/uploads/2018/09/EW-09-27-18-Energy-Justice-in-California.mp3
California put in place a cap-and-trade program in 2013. In such a program, companies pay penalties if they exceed a cap in carbon emissions but can buy and sell allowances that permit them to emit a given amount. Trading gives companies a strong incentive to save money by cutting emissions. Since taking effect, the California program has raised more than $6.5 billion and is the fourth largest in the world.
