Lake Baikal
Lake Baikal is an ancient and massive body of freshwater found in the mountainous Russian region of Siberia. Deep and voluminous, Lake Baikal holds 20% of the planet’s unfrozen freshwater. And it’s often been described as the world’s cleanest and most pristine lake.
New Doubts About GMO Crops
Genetically modified crops have been at the center of a great deal of controversy for a number of years. There have been widespread fears that they are unsafe to eat. Continuing studies have indicated that those fears appear to be unsubstantiated.
Restorative Ocean Farming
The conventional aquaculture industry has often been associated with many of the same problems that beset land-based agriculture: creating sterile monocultures, fouling the environment with pesticides, antibiotics and organic pollutants, and spreading diseases.
Jet Fuel From Steel Plants
Industries around the world are working to reduce their carbon emissions. One very carbon-intensive industry is the airline industry and it is struggling to find ways to reduce its emissions even while air travel continues to be on the rise worldwide.
Houseplants And Clean Air
Many of us like to have houseplants. They add a bit of nature to our homes and they look nice. It turns out that they have health advantages as well.
Restoring An Urban River
Those of us who grew up in Los Angeles are quite familiar with the L.A. River. It’s not much of a river at all. Just a 51-mile-long concrete drainage ditch that shows up from time to time in movies like The Italian Job and Terminator 2.
Size Matters
One of the crowning achievements for wildlife protection in the US was the establishment of the National Wildlife Refuge system in the 1930s, when the populations of waterfowl were perilously low. Refuges provided breeding and migratory habitat that has allowed a remarkable recovery of many species of ducks and geese.
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 Incredible Shrinking Bison
As the climate warms, all sorts of things are happening in the environment. We know about shrinking ice caps, retreating glaciers, strange winter weather, and so forth. But there are other things that may happen that are unexpected and puzzling.
Are All Invasive Species Bad?
The conventional wisdom is that invasive species are bad news and we constantly hear about the dangers of foreign plants and animals moving into new territories.
Lake Ohrid: Respecting An Elder
Nestled in the mountainous border between southwestern Macedonia and eastern Albania, Lake Ohrid is a deep, ancient lake. Its waters provide refuge to hundreds of plants and animals that live nowhere else, including seventeen species of fish.
Human Carbon
There is a powerful correlation between the rise of the human population and the rise of atmospheric CO2 during the past few decades. Could the carbon dioxide we emit when we breathe be a factor in global warming? According to biogeochemist Bill Schlesinger, the answer is a resounding no. Here’s why.
Biodiversity And Our Diet
We often talk about the importance of biodiversity in maintaining the health of ecosystems. One ecosystem we don’t often think about in those terms is the human diet.
Planning Cooler Cities
Anyone who has walked the streets of New York City or Washington, D.C. on a stifling summer day can attest to the fact that cities feel hotter. It’s not a matter of perception.
