Breathe Better With Air Conditioning

September 15, 2017 By EarthWise

https://earthwiseradio.org/wp-content/uploads/2017/09/EW-09-15-17-Breathe-Better-with-Air-Conditioning.mp3

For many people, commuting to and from work is a time-consuming, stressful part of their lives.  In fact, the average American spends nearly an hour a day facing traffic jams and congested highways.   There are direct health hazards in commuting as well.  Drivers are exposed to increased amounts of air pollutants that have been linked to a wide range of medical problems including cardiovascular disease, respiratory issues and even lung cancer.

Ditching Gas And Diesel Cars

September 14, 2017 By EarthWise

https://earthwiseradio.org/wp-content/uploads/2017/09/EW-09-14-17-Ditching-Gas-and-Diesel-Cars.mp3

Electric cars represent only a tiny fraction of the overall auto market.  The numbers are growing, most certainly, but they are still quite small in most places.   The recent start of production of the Tesla Model 3 has attracted quite a bit of attention to electric cars, but in many countries, there is much more to the story than just media buzz about a new car.

The Perils Of Air Conditioning

September 12, 2017 By EarthWise

https://earthwiseradio.org/wp-content/uploads/2017/09/EW-09-12-17-The-Perils-of-AC.mp3

The battle to reduce greenhouse gas emissions is heavily focused on replacing fossil fuel power plants with renewable energy and replacing internal combustion engine autos with electric cars.  But there is another elephant in the room:  air conditioners.

A Faster Car Battery

September 11, 2017 By EarthWise

https://earthwiseradio.org/wp-content/uploads/2017/09/EW-09-11-17-A-Faster-Car-Battery.mp3

There is more and more interest in electric cars and, based on the half million advance orders for the Tesla Model 3, more and more of us plan to be driving them.  For many of us, the technology is already good enough to meet most if not all of our motoring needs.

Genetic Engineering And Conservation

September 8, 2017 By EarthWise

https://earthwiseradio.org/wp-content/uploads/2017/08/EW-09-08-17-GE-and-Conservation.mp3

Genetic engineering, or equivalently synthetic biology, is a multi-billion-dollar enterprise involved in pharmaceuticals, chemicals, biofuels and, of course, agriculture.  In these fields, it is already the source of a great deal of controversy.  But there is increasing interest in using synthetic biology (or synbio) technology as a tool for protecting the natural world, which is a prospect some find tantalizing and others find absolutely terrifying.

Removing Heavy Metals From Water

September 7, 2017 By EarthWise

https://earthwiseradio.org/wp-content/uploads/2017/09/EW-09-07-17-Removing-Heavy-Metals.mp3

Clean and abundant water is the most essential need for all human societies and the supply of it is threatened by increasing populations and volatile climate patterns.   The quality of water is threatened by a host of contaminants, most of our own making.

A Floating Wind Farm

September 5, 2017 By EarthWise

https://earthwiseradio.org/wp-content/uploads/2017/09/EW-09-05-17-A-Floating-Wind-Farm.mp3

Offshore wind farms are becoming increasingly important around the world.  Europe has thousands of wind turbines off its coasts generating more and more of its power.  The first offshore wind farm in the U.S. opened for business last year and more are on the way.

The Dirty Laundry On Dirty Laundry

We’ve discussed the problem of microplastics polluting our oceans at great lengths on this program before.  Much of the small plastic particles result from the breakdown of plastic litter, such as plastic bags, packaging, and other materials.  Another source is microbeads, which are often found in health products such as face scrubs and even some toothpastes.  But there is a another source of microplastic pollution that is quite troubling: dirty laundry.

Electric Cars For Real This Time?

August 29, 2017 By EarthWise

https://earthwiseradio.org/wp-content/uploads/2017/08/EW-08-29-17-Electric-Cars-for-Real.mp3

Electric cars have been around for a long, long time.  The first ones appeared in the mid-19th century.  Around the turn of the 20th century, they were popular for taxi cabs in places like New York City.  But within about 10 years, they mostly disappeared.  In the 1990s, electric cars had a brief revival with vehicles like the General Motors EV1.  But again electric cars mostly vanished.

Septic Systems and Water Contaminants

August 28, 2017 By EarthWise

https://earthwiseradio.org/wp-content/uploads/2017/08/EW-08-28-17-Septic-Systems-and-Water-Contaminants.mp3

A recent study has shown that septic systems in the U.S. routinely discharge pharmaceuticals, consumer product chemicals and other potentially hazardous substances into the environment.   The comprehensive study, published in the journal Environmental Science & Technology, raises health concerns since these chemicals can end up in groundwater and drinking water supplies.

Restoring Sediment To Save Wetlands

August 25, 2017 By EarthWise

https://earthwiseradio.org/wp-content/uploads/2017/08/EW-08-25-17-Restoring-Sediment-to-Save-Wetlands.mp3

The world’s rivers carry billions of cubic yards of sediment – sand, silt and other material – and transport it to wetlands and coastal areas.  Until fairly recently, this was viewed as a negative thing.  But that has changed.

Using Manganese To Transform CO2

https://earthwiseradio.org/wp-content/uploads/2017/08/EW-08-23-17-Using-Manganese-to-Transform-CO2.mp3

Carbon dioxide is not a very popular substance.  As a greenhouse gas, it is the chief culprit in climate change and, as such, the world continues to seek solutions for preventing its release in the environment.

https://earthwiseradio.org/wp-content/uploads/2017/08/EW-08-17-17-Can-The-Great-Barrier-Reef-Be-Saved.mp3

There have been many stories in the media about the ongoing environmental crisis at Australia’s Great Barrier Reef.  Over the past two years, the reef has lost almost half of its coral because of bleaching events.   Faced with this situation, the Australian government created the Reef 2050 Plan, a strategy to protect and maintain the reef through the year 2050.

Terrible traffic in cities around the world is a real blight on urban life.  Increasingly, there are many cities where you simply don’t want to have to go anywhere by car during morning and evening rush hours.

Sustainable Ethanol

https://earthwiseradio.org/wp-content/uploads/2017/07/EW-08-10-17-Sustainable-Ethanol.mp3

Most gas stations in the U.S. sell a blend of 90% gasoline and 10% ethanol.  Mandated by legislation, the 14 billion gallons of ethanol consumed annually by American drivers is mostly made from fermented corn.   Producing this ethanol requires millions of acres of farmland.

Tipping Points

August 9, 2017 By EarthWise

https://earthwiseradio.org/wp-content/uploads/2017/08/EW-08-09-17-Tipping-Points.mp3

A tipping point is a point in time when a small thing can make a big change happen.  The term was popularized in sociology in recent decades, but really comes from physics where is refers to adding a small amount of weight to a balanced object causing it to topple over.

New Milestones For Renewable Energy

August 7, 2017 By EarthWise

https://earthwiseradio.org/wp-content/uploads/2017/08/EW-08-07-17-New-Renewable-Energy-Milestones.mp3

There is no question that solar power has been growing by leaps and bounds in recent years, but whenever one really looked at the numbers, it seemed to still be only a tiny fraction of the country’s power generation – until quite recently, less than one percent.
