Industry has made efforts to reuse or to transport shale gas wastewater to deep injection wells, but wastewater is still discharged into the environment, after being treated, in some states. 

In western Pennsylvania, water that comes from Marcellus shale is naturally high in salinity and radioactivity but a new Duke study examined the quality of shale gas wastewater resulting from hydraulic fracturing and found that the stream water above and below the Josephine Brine Treatment Facility disposal site that is derived from the Marcellus shale gas flowback water showed elevated levels of radioactivity, salts and metals.

High concentrations of some salts and metals were also observed in the stream water.


This paper reviews recent studies and particularly the effects of Climate Change in the North Tropical Atlantic by studying atmospheric conditions that prevailed in 2005 ; Coral Bleaching HotSpot and Hurricane Katrina.

In the aim to better understand and estimate the impact of the physical phenomenon, i.e. Thermal Oceanic HotSpot (TOHS), isotopic studies of δ18O and δ13C on marine animals from Guadeloupe (French Caribbean Island) were carried out.

Recorded measures show Sea Surface Temperature (SST) up to 35°C in August which is much higher than data recorded by NOAA satellites 32°C.

Calcium helps strengthen bones in people but it is also a critical nutrient for healthy tree growth and new research shows that adding it to the soil helps reverse the decades-long decline of forests ailing from the effects of acid rain. 


A $12 million program wants to revolutionize current farming methods by giving crops the ability to thrive without using costly, polluting artificial fertilizers.

Four teams are using synthetic biology to create new components for plants: a global search for a mysterious lost bacterium with significant unique functions; work to engineer beneficial relationships between plants and microbes; and an effort to mimic strategies employed by blue-green algae.

The U.S. National Science Foundation (NSF) and U.K.'s Biotechnology and Biological Sciences Research Council (BBSRC) made the awards following an 'Ideas Lab' that focused on new approaches for dealing with the challenges of nitrogen in the growing global food demand.  

Satellite observations made from 1982 to 2010 found that warm, arid regions are getting greener. 


The Canadian boreal forest,  stretching from the Yukon in the west to Newfoundland and Labrador in the east, remains one of the world's great natural treasures.

The ecologically diverse region contains the largest blocks of intact forest and wetlands left on Earth and scientists have found 1 billion to 3 billion nesting birds from 300 species there. Its abundant wildlife and freshwater have sustained Aboriginal communities for millennia.

Food waste is a big problem, particularly in the developing world, but also in the rich world.   I have seen quite a bit written recently about how one of the best ways to improve the sustainability and lower the footprint of food production would be to reduce waste.  While this is absolutely true, the perspective that has been missing is that we have been working on this issue for a very long time and have made significant advances over the last several decades.

While America has dramatically dematerialized its environmental footprint in recent decades, producing far more food on far less land than 30 years ago, that's not true for the rest of the world. 

Heavy financial incentives in places like Europe - which accounts for 85% of the agricultural subsidies for the entire world - mean there is no reason to embrace modern science and technology. But a new paper notes that allowing land use to be determined purely by those agricultural constituencies results in considerable financial and environmental costs to the public. 


There was a period of time when hunters were the greatest conservationists.  Think President Teddy Roosevelt, who evangelized national parks and setting aside wilderness for the public.

Later, environmentalism became an occupation for urbanites and they distanced themselves from sportsmen and people who enjoyed nature - they even listed them as enemies, in the case of hunting and fishing.
