Wildlife and Habitat
Carbon Dioxide And Bees
The decline of bee populations worldwide is a serious problem that threatens much of agriculture. From 2006 to 2011, losses in managed honeybee colonies in the U.S. averaged 33 percent a year. In recent years, beekeepers have had to replace 50 percent of their colonies each year.
Nile Crocodiles In Florida
Nobody really knows how many alligators live in Florida. It’s estimated that there are anywhere from 1.3 million to 2 million alligators in the Sunshine State, which means there’s one gator for every 10-15 Floridians. It’s this ratio that makes it just about impossible for someone living in Florida not to encounter an alligator at some point. And if you have seen one recently and thought it looked a little bigger, you may be onto something.
Sponsoring National Parks
Everybody loves national parks. They offer scenic wonders, opportunities to commune with nature, and a chance to get away from the pervasive commercialization that fills our lives. But that may soon change.
Less Sulfur In The Soil
Acid rain is rain containing high levels of nitric and sulfuric acids. The main culprit for it is the burning of fossil fuels, particularly coal-burning power plants. The most serious effect of acid rain is the creation of toxicity in lakes, wetlands and other aquatic environments, doing great harm to a wide range of aquatic animals.
The State Of The Birds
The North American Bird Conservation Initiative recently released its annual “State of the Birds’ report, which is a comprehensive analysis of North American birds. And as with many other things these days, we’re not doing well.
Trouble For Vultures
When we think of vultures, we picture big, ugly birds circling over a carcass in the desert. They are a stereotypical harbinger of death. But in many parts of the world, vultures are in danger of disappearing. Our knee-jerk reaction might well be “good riddance”, but as is the case for pretty much all participants in ecosystems, vultures have an important role to play. And when they aren’t around to play that role, bad things can happen.
Mobile Apps Empower Citizen Science
Citizen scientists play a vital role in raising awareness about the health of our nation’s freshwater resources. Their efforts can help document water clarity and track harmful algal blooms and other indicators of poor water quality instrumental to sound management.
A Giant Dam Removal Project
In early April, the U.S. Government, the states of Oregon and California, and the utility Pacificorp signed an agreement that will lead to the removal of four dams on the Klamath River by 2020, amounting to one of the largest river restoration efforts ever undertaken in the United States.
Wildlife Adapting To Cities
By the year 2030, two-thirds of humanity will live in cities— but we are not alone. Cities are filled with food and natural predators are scarce, so many creatures have moved in with us.
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.
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.
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.
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.
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.
