Coal Power Plant

[audio:http://wamcradio.org/EarthWise/wp-content/uploads/2012/11/EW-11-16-12-Coal-Ash.mp3|titles=EW 11-16-12 Coal Ash]

Coal is a rock, albeit a soft rock that is mostly made of carbon.  When we burn coal, this carbon is released to the atmosphere as carbon dioxide.  A portion of the remaining materials, composing about 1% of coal, is left behind as ash.  [Read more…] about Coal ash – waste piles we don’t often consider

The carbon footprint of your household trash

Household Trash

[audio:http://wamcradio.org/EarthWise/wp-content/uploads/2012/10/EW-11-07-12-Household-Trash.mp3|titles=EW 11-07-12 Household Trash]

Americans dispose of an average of 7.1 pounds of trash per day, or well more than a ton yearly. That’s per person, and it doesn’t include what we put in the recycling bin. Our non-recycled trash goes largely to landfills, some of them a long distance away. Trash is transported by truck, train, or even ship—all of which use fossil fuels.

Economic growth vs. quality of life

October 29, 2012 By EarthWise

Teacher Education Program

[audio:http://wamcradio.org/EarthWise/wp-content/uploads/2012/08/EW-10-29-12-Economic-Growth.mp3|titles=EW 10-29-12 Economic Growth]

I recently attended a breakfast of business executives, hosted by the local chamber of commerce.  All lamented the lack of economic growth in the community, particularly the lack of growth in tax revenues to support public services.  Similar conversations play out across upstate New York and the Midwest, where cities have lost their industrial base and the best talent has moved away.

The articulated solution—bring in more people.  Now as a plumber, the Chair of this meeting probably sees this as reasonable. More people means more houses to build, more toilets to fix, and a higher income.  But, is that real growth?

In the long term, I would argue that economic growth based solely on population growth is hollow.  What we need to pursue is growth in quality of life—not more people, but people living better. A focus on quality of life is a focus on education, innovation, research, and development.

A vibrant, sustainable steady-state economy doesn’t divide up a limited resource base among increasing numbers—instead it affords each productive citizen a higher quality of life while extracting less from the natural environment.  And a basic tenet for quality of life is clean air and clean water. Nurture a healthy environment and business will come.

This fall, when candidates are debating how to stimulate our sluggish economy, pay attention to what they are really promoting.  And choose growth in quality, not growth simply based on more people in your community and the nation.

Wilting corn

[audio:http://wamcradio.org/EarthWise/wp-content/uploads/2012/09/EW-10-19-12-Ag-War.mp3|titles=EW 10-19-12 Ag War]

This year, drought dealt a heavy blow to U.S. corn production, with the U.S. Department of Agriculture listing half the crops in poor or very poor shape. Yields are down and corn prices are rising–bad news for food processors, dairy operations, and livestock farms. Further complicating things, low inland water levels are causing shipping headaches for the barges that haul the grain. [Read more…] about Tough times for corn

Exporting our carbon emissions

Our neighbors in Canada are sitting on an enormous energy reserve. The Canadian oil sands, located in Alberta, cover a swath of land the size of England. It is estimated they contain 170 billion barrels of recoverable oil, second only to Saudi Arabia.  [Read more…] about Trying to clean up dirty oil sands

Recycling – it’s the nature of nature

Recycling

[audio:http://wamcradio.org/EarthWise/wp-content/uploads/2012/09/EW-10-01-12-Recycling.mp3|titles=EW 10-01-12 Recycling]

The Earth is a giant recycling machine.  Every year, a portion of the seafloor merges into the Earth’s crust.  As these materials travel downward, they cause earthquakes.  The land surface does not wear down because in other areas, mountains are uplifted, roughly balancing the volume of materials lost from the sea floor.  The Earth is thus a recycling machine on a grand scale.

[audio:http://wamcradio.org/EarthWise/wp-content/uploads/2012/09/EW-09-28-12-Nanoparticles.mp3|titles=EW 09-28-12 Nanoparticles]

Increasingly, we hear about the use of nanoparticles and nanotechnology in new products.  Tiny particles of silver act as anti-microbial agents in clothing. Similarly small particles of titanium enhance the brightness and application of paints, cosmetics, and sunscreen.  And particles of a rare element, cerium, remove otherwise noxious components from diesel exhaust.  [Read more…] about Nanoparticles—tiny particles that pack a punch
