The wireless age has introduced countless devices that many of us can’t live without, like cell phones, laptop computers and wifi routers. Like all electronics they communicate using electromagnetic frequencies – or EMFs. Some people worry that EMFs are making them sick – and say that technology should slow down, as Amy Standen reports.
This is the classic environmental story: a species in trouble because of what our species is doing. It's happening all over the world. But there are people tackling these problems one by one, coming up with simple ways of changing our behavior. This week we take a look at the plight of the foothill yellow-legged frogs.
The Foothill Yellow Legged Frog has been wiped out from more than half of its' historic range along California's coast and central valley. Many biologists see this tiny amphibian as a canary in the coalmine – an early indication of an ecosystem gone wrong.
The Environmental Protection Agency is reviewing scientific assessments of a controversial strawberry fumigant scheduled for use in California, as well as opening up a public comment period on the toxic pesticide, according to U.S. Sen. Dianne Feinstein and the environmental law group Earthjustice.
Indian reservations hold an estimated 10 percent of the nation's renewable energy resources — hot, windy tracts that suddenly seem more valuable than ever. The Campo tribe, near San Diego, has taken the lead, building the country's only utility-scale wind installation on Indian land. Plans are afoot to triple the project. But tribe members say tax incentives and other federal programs put Indians at a disadvantage.
This week, we continue our series "33 by 20," a look at California's ambitious renewable energy goals. Solar and wind power are booming across the state. But renewables have a downside: there are times when the sun doesn't shine and the wind doesn't blow. California utilities are looking to smooth out those bumps with a new strategy: storing electricity.
Energy storage (through batteries) is something we use everyday in our cell phones and computers. So it may be a little surprising that when it comes to the electric grid, storing energy is something that's rarely done.
As the state dries out from a long, rainy winter, the battle over water rights in the Sacramento Delta continues. Water contractors are hoping an upcoming court ruling will find that water pumps are not the only threat to the imperiled Delta Smelt. Some of the blame is getting pinned on a bigger fish that happens to have an appetite for endangered species. Alison Hawkes reports.
Researchers at UC Davis are collecting DNA from dogs seized in police raids on dogfighting operations. The goal is to create a database to help identify and prosecute the extensive underground breeding programs that sell puppies for as much as $50,000 to dogfighting rings. But the database is controversial among some animal rights activists, who believe it would allow shelters to euthanize dogs whose DNA match fighting lineages.
Dogfighting rings, as we report in this story, rely on a sophisticated, interstate network of breeders, just like you'd find for any other breed.
In April, California continued its ambitious efforts to restore declining ocean fisheries by creating 21 new marine protected areas between Half Moon Bay and Mendocino County. In all, fishing would be banned or reduced in 20 percent of state waters there. But with the state budget crisis, how will California enforce these rules?
Argentine ants have had amazing success as an invasive species in the US. Their West Coast super colony numbers in the billions and spans from Mexico to Oregon. But aside from invading homes, they've had a dramatic effect on native ants and local ecosystems.
If you've ever had small, black ants in your kitchen, chances are they're Argentine Ants. These invasive insects have spread across California, forming what some scientists say is one of the largest colonies on Earth. They're also harming native ants. Now, scientists are developing ways to stop the invasion, by learning the language ants use to communicate. Lauren Sommer reports.
A plan that requires California's utilities to generate one third of their electricity from solar, wind and other types of clean energy by 2020 has been held up by a glacially slow permitting process. The Panoche Valley, south of Hollister, is finding itself in the center of one of those debates.
California has set ambitious goals for a transition to clean, renewable energy: 33 percent by 2020. Some are skeptical that the goal is within reach.QUEST and Climate Watch continue to examine the promise and pitfalls of this historic transformation. Craig Miller reports on one Silicon Valley company's controversial proposal for Panoche Valley.
The Schwarzenegger Administration plans to approve a new chemical called methyl iodide, which is used by strawberry farmers. Although methyl iodide can cause cancer and miscarriages, regulators say that protective measures like respirators and buffer zones will keep farm workers safe. Scientists consulting for the state say these measures often fail, and methyl iodide is too toxic to take chances. Amy Standen reports.
How much can we count on respirators, buffer zones and other tools to protect people from a toxic chemical? That's the focus of this week's QUEST radio story.
Methyl bromide – a powerful fumigant used by strawberry growers to sterilize the soil before plants go in – was found to harm the Earth's ozone layer. Strawberry farmers have been clamoring for a replacement, and they may get their wish if the state approves a chemical called methyl iodide. But some state scientists say it could cause cancer and miscarriages in farm workers and nearby communities.
