The City of Toledo has issued a "Do Not Drink" advisory for residents served by Toledo Water after chemical tests confirmed the presence of unsafe levels of the algal toxin Microcystin in the drinking water plant’s finished water. The advisory, spanning three counties in Ohio and one in Michigan, leaves more than 400,000 people in the Toledo area without drinking water.
"Do not drink the water," Melanie Amato, public information officer for the Ohio Department of Health, told Circle of Blue. "You can shower in it, bathe in it, but do not try to ingest it. That means no washing dishes; you can brush your teeth with it as long as you don’t swallow any water, but we recommend using bottled water for that as well."

Many studies have shown the potential for global climate change to cut food supplies. But these studies have, for the most part, ignored the interactions between increasing temperature and air pollution -- specifically ozone pollution, which is known to damage crops.
A new study involving researchers at MIT shows that these interactions can be quite significant, suggesting that policymakers need to take both warming and air pollution into account in addressing food security.

Ecologists may be underestimating the impact of logging in old-growth tropical forests by failing to account for subtleties in how different animal groups respond to the intensity of timber extraction, argues a paper published today in the journal Current Biology. The study, led by Zuzana Burivalova of ETH Zurich, is based on a meta-analysis of 48 studies that evaluated the impact of selective logging on mammals, birds, amphibians, and invertebrates in tropical forests. Burivalova, together with co-authors Cagan Sekercioglu and Lian Pin Koh, found that biodiversity is inversely proportional to logging intensity.

Unless your skin is about a foot thick, swimming and surfing in the Pacific Ocean for hours at a time requires a wetsuit to stay warm and comfortable. That comfort, however, comes at a price as the vast majority of wetsuits are made from petroleum-based neoprene. The material is durable and does the job, but its manufacture is a carbon-intensive and toxic process. Now Patagonia is aggressively promoting its plant-based wetsuit technology with the goal to have it become a game-changer in the surf industry.

A combination of coastal defences and rising sea levels could change typical UK tidal ranges, potentially leading to a higher risk of flooding, say scientists.
The researchers wanted to find out how tides around the UK might respond to changes in sea level over the next century depending on the level of coastal defences in place.

Un nuevo estudio muestra que las interacciones entre el aumento de la temperatura y la contaminación del aire pueden ser muy importantes cuando se trata de abordar la seguridad alimentaria.
Llevado a cabo en parte por los investigadores del MIT, un estudio examinó en detalle la producción mundial de los cuatro cultivos principales de alimentos...
