Tiny Forest Pests Cause Big Problems
Each year, more than 25 million shipping containers enter the U.S. All too often, highly destructive forest pests are lurking among their imported goods. Wood boring insects arrive as stowaways in wood packaging, such as pallets and crates. Other forest pests and pathogens hitchhike in on foreign-reared plants bound for American nurseries.
Electric Car Boom
The introduction of the Tesla 3 and the 400,000 advanced orders for the vehicle have put the spotlight on electric cars recently. But despite all the buzz, electric cars are sill only a tiny piece of the US car market: about 0.66 percent last year.
The BP Oil Spill
In 2010, an explosion on the BP-owned Deepwater Horizon drilling rig released more than 200 million gallons of oil into the Gulf of Mexico. Some of the oil was recovered, burned, or dispersed at sea, while some washed up onto the shorelines of Texas, Louisiana, Mississippi, Alabama, and Florida.
Electric Buses And Trucks
We hear a great deal about electric cars these days. Will people buy them? Are they worth it? And, of course, there is the tremendous buzz surrounding Tesla’s forthcoming moderately-priced car. But there is also lots of activity in electrifying larger vehicles, including garbage trucks, city buses, and medium-sized trucks used by freight companies like FedEx.
Preventing Toxic Algal Blooms
We have talked about the growing problem of toxic algal blooms on a number of occasions. The increasing occurrence of these blooms has been associated with rising temperatures and carbon dioxide levels as well as the presence of wastewater nutrients and agricultural fertilizers in rivers, lakes and reservoirs. The most notable incident occurred in the summer of 2014, when algae contamination in Lake Erie left 400,000 residents in Ohio and Michigan without water for 72 hours.
Clean Fossil Fuel Electricity
Renewable energy sources like wind and solar power are getting cheaper all the time and are, in many places, competing head to head on price with traditional fossil fuel generation. The ultimate goal is to replace polluting energy sources entirely, but even under the most optimistic scenarios, fossil fuel plants aren’t just going to disappear very quickly.
Human-Caused Earthquakes
Oklahoma has had its share of disasters over the years. It has seen tornado outbreaks, massive wildfires, huge dust storms and even onslaughts of tumbleweeds. But one thing it was not known for is earthquakes.
Coral Bleaching On The Great Barrier Reef
It was already well-known that coral bleaching was a serious problem in the Great Barrier Reef, but extensive aerial surveys and underwater dives have now revealed the shocking extent of the problem.

Growing More Food On Less Land
There are predictions that the world’s population could reach 10 billion by the year 2050. Whether population growth can be slowed down enough to prevent this remains to be seen. Regardless, it is clear that we need to figure out how to feed many more people than we have today and we are not even doing that good a job of feeding the current population.
Natural World Heritage Sites
Natural world heritage sites exemplify the world’s greatest areas of natural beauty, ecology, geology, and biodiversity. They are recognized internationally for their value as places with significance that is “so exceptional as to transcend national boundaries and be of common importance for present and future generations of all humanity.” Many of these areas also are a vital source of food, fuel, and water for rural communities, and provide a revenue stream for national economies through tourism and recreation. The livelihoods of some 11 million people are directly dependent on these areas.
Stop Putting Food Waste Down The Drain
Should we really be putting food scraps down our sinks? Advertisements for kitchen garbage disposals assure us that these devices are a ‘hygienic way of eliminating waste and keeping odors at bay’ – but behind marketing materials questions remain.
Scottish Coal
The Scottish government has an ambitious plan to meet 100 percent of its demand for electricity from renewable sources by 2020. Like much of the world, Scotland has produced significant amounts of its electricity by burning coal for more than 100 years. But no longer.
A Floating Wind Farm
The world’s first floating wind farm is being built 15 miles off the northeast coast of Scotland. The Hywind pilot park, expected to come online late next year, will generate enough power for 20,000 homes. The location will take advantage of average local North Sea wind speeds in excess of 20 miles per hour.
A Wind-Solar Streetlight
The Caribbean island nation of Grenada has installed a wind and solar powered off-grid streetlight. An Irish company called airsynergy has developed the underlying technology which it calls a Remote Power Unit or RPU.
Climate Change Redistributes Global Water Resources
Worldwide, climate change isn’t just raising temperatures, its also altering the distribution of water. So reports an inventive new study that tapped into archival water samples to reveal how sources of precipitation have changed over time.
