AP Explains: Farm runoff and the worsening algae plague
Harmful algae blooms have become a top water polluter, fueled by fertilizers washing into lakes, streams and oceans. Federal and state programs have spent billions of dollars on cost-sharing payments to farmers to help prevent nutrient runoff, yet the problem is worsening in many places. Here's a look at the algae menace and what's being done:
Blooming algae choking waters around the world
WASHINGTON (AP) — Projected increases in rain from global warming could further choke U.S. waterways with fertilizer runoff that trigger dead zones and massive algae blooms, a new study said.
If greenhouse gas emissions keep rising, more and heavier rain will increase nitrogen flowing into lakes, rivers and bays by about 19 percent by the end of the century, according to a study in Thursday's journal Science .
Lake Erie algae in 2017 matches third-most severe on record
TOLEDO, Ohio (AP) — The toxic algae that spread across Lake Erie this summer roughly matched its third-most severe bloom in 15 years, government researchers said Tuesday.
The algae outbreak on the shallowest of the Great Lakes had two peaks this year in August and again in mid-September, according to the National Oceanic and Atmospheric Administration.
Advocacy groups: EPA not doing enough to protect Lake Erie
TOLEDO, Ohio (AP) — Environmental advocates who sued the U.S. Environmental Protection Agency because they believe not enough is being done to address the toxic algae problem in Lake Erie said they think the agency's response to the suit only bolsters their argument.
The groups want the EPA to declare that the western end of the lake is impaired by the algae that's a threat to drinking water and fish. Such a designation could lead to stricter pollution controls.
Ohio mayor asks Trump for help combating Lake Erie algae
TOLEDO, Ohio (AP) — Three years after toxic algae in Lake Erie tainted the drinking water for more than 400,000 people, many are still leery about what's coming out of their faucets.
Some have taken to stockpiling bottled water in the summer months when algae blooms blanket the western end in the shallowest of the Great Lakes.
TOLEDO, Ohio (AP) — Satellites in space and a robot under Lake Erie's surface are part of a network of scientific tools trying to keep algae toxins out of drinking water supplies in the shallowest of the Great Lakes.
It's one of the most wide-ranging freshwater monitoring systems in the U.S., researchers say, and some of its pieces soon will be watching for harmful algae on hundreds of lakes nationwide.
Building Boom Threatens Wildlife-Rich FL Lagoon
BANDAR AL-ROWDAH, Oman (AP) — The Gulf of Oman turns green twice a year, when an algae bloom the size of Mexico spreads across the Arabian Sea all the way to India.
Scientists who study the algae say the microscopic organisms are thriving in new conditions brought about by climate change, and displacing the zooplankton that underpin the local food chain, threatening the entire marine ecosystem.
