Wildlife Corridors
It is widely thought that we are in the midst of the 6th great mass extinction of species on Earth and, unlike the previous ones that were caused by things like asteroid impacts or ice ages, this one is caused by us. Our impact on the climate, on natural resources, on landscapes and habitats, and more, has wreaked havoc on ecosystems across the globe.
Wiping Out Wildlife
According to a new report from the World Wildlife Fund, the world’s animal populations have suffered widespread population declines in the last half century. And thousands of species are now scrambling to survive.
Climate Change And Fish
According to a recent study published in the journal Global Change Biology, rising CO2 levels in the ocean can disrupt the sensory systems of fish and can even make them swim toward predators and ignore the sounds that normally deter them from risky habitats.
Wilderness Lost
Wilderness areas are strongholds for biodiversity. They buffer and regulate local climates, and they support many of the world’s most politically and economically marginalized communities. While there is a great deal of attention being paid to the loss of species around the world, there is relatively little focus on the loss of entire ecosystems. Simply put, wilderness is on the decline, and it has been ever since human civilization began its inexorable expansion.
Catching Kelp In Maine
Farming, forestry, mining and recreation are the primary vocations in rural America. In coastal areas like Maine, fishing joins the list. And for Maine, commercial fishing has long been a major engine for the economy.
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.
Sunscreen And Coral Reefs
Coral reefs are great tourist attractions. Nearly a million species of fish, invertebrates and algae live in these biodiversity hotspots and they generate billions of dollars yearly from the tourism industry.
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.
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.
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.
Ending The Protection Of Grizzly Bears
Grizzly bears, also known as North American brown bears, once roamed much of North America and symbolized the continent’s untamed wilderness. But hunters and trappers nearly wiped them out across most of the Lower 48 states by the late 1800s.
De-Extinction: Opening Pandora’s Box
De-extinction, or the act of bringing extinct species back from the dead, has been riding a wave of enthusiasm. Nearly 2 million people have watched Steward Brand’s TED talk on the topic, and Beth Shapiro’s book How to Clone a Mammoth has received rave reviews.
Cod And Global Warming
Atlantic cod has been the basis of a major fishing industry in the Gulf of Maine for centuries and is a key species in the local ecosystem. Overfishing decimated the population of cod and in 2010, fisheries managers imposed a series of restrictions on harvesting the fish in order to try to help the species to rebound.
