Poetry in Motion: Power Plant Will Use Ocean Tides to Power 155K Homes
A planned power plant in Wales may look like the Guggenheim Museum but its benefits will outweigh the beauty: it will use the ocean tides to power 155,000 homes.
Fish in today's oceans contain far lower levels of mercury, DDT and other toxic chemicals than at any time in the last 4 decades, says a major review.
Fish in today's oceans contain far lower levels of mercury, DDT and other toxic substances than at any time in the last four decades, according to a major review from the Scripps Institution of Oceanography in California.
"Looking at nearly 2,700 studies of pollutants in fish, the researchers saw steady, significant drops in the concentrations of a wide range of contaminants known to accumulate in fish — from about 50% for mercury to more than 90% for PCBs," reports the LA Times.
Scientists say the drop is due to federal restrictions on coal plant emissions that have resulted in less mercury being transported by rainfall into the ocean.
However, researchers warned that many fish in the wild still have pollutant levels considered unsafe if consumed frequently by humans.
