Parece que cada vez más cantidad de los pescados disponibles en el supermercado y en los restaurantes es de granja. ¿Es esto bueno o malo? Probablemente un poco de ambas cosas. La crÃa de peces en las piscifactorÃas no afecta a los peces silvestres en gran medida, pero las granjas de peces deben estar bien situadas y bien dirigidas para evitar problemas. ¡No son ecosistemas naturales!

As part of the President's Climate Action Plan – Strategy to Reduce Methane Emissions, the U.S. Environmental Protection Agency (EPA) is proposing updates to its air standards for new municipal solid waste (MSW) landfills. These updates would require certain landfills to capture additional landfill gas, which would reduce emissions of methane, a potent greenhouse gas, and help further reduce pollution that harms public health.

You may not realize it, but at this very moment, you’re probably wasting electricity. Don’t feel too bad though; the fact of the matter is, most people are using more electricity than they need.

Millions of tons. That's how much plastic should be floating in the world's oceans, given our ubiquitous use of the stuff. But a new study finds that 99% of this plastic is missing. One disturbing possibility: Fish are eating it.
If that’s the case, "there is potential for this plastic to enter the global ocean food web," says Carlos Duarte, an oceanographer at the University of Western Australia, Crawley. "And we are part of this food web."
