Light pollution impeding rainforest regeneration: Seed dispersing bats avoid feeding in light polluted areas

When you think about pollution, usually dirty chemical substances pop to mind; maybe some petroleum, or waste water – light pollution doesn’t usually take the first places. But a new study conducted by scientists from the German Leibniz Institute for Zoo and Wildlife Research Berlin (IZW) showed that light pollution can also have a significant […]

Turning methane leaks from fracking into gasoline; an interesting option, but not enviro friendly

Hydraulic fracking has grown to unimaginable hights in the past few years, growing by some 20% a year, and reaching a total market cap of $37 billion today. Recent tumbling prices for natural-gas have slightly detered exploration, but North America at least, which accounted for 87 percent of the fracking market last year, shows no […]

Environmental refugees? Wealthy Chinese depart mainland in search for clean air

The low quality of the Chinese air is more than simply a nuisance – China has by far the worst air quality out of all the industrialized countries, and it’s estimated that 16 of the world’s 20 most polluted cities are in China. Needless to say this significantly raises mortality and causes a myriad of […]

Leaking natural gas may be a significant contributor to global warming

Since the turn of the industrial revolution, round the 1750′s, the share of methane gas in the atmosphere has nearly doubled. Methane molecules are roughly 26 times more potent than carbon dioxide in trapping heat, and thus they’re one of the most dangerous types of emissions. Burning methane, however, is a whole lot better (actually […]

The top 7 countries responsible for global warming

A new study published in Environmental Research Letters  ranks the the top seven contributing countries to global warming. Together, these nations account for more than 60 percent of pre-2005 global warming. Before we go on to pointing fingers, it’s important to note that the study incorporates various metrics. This way you can see how each country dumps […]

Smog in Beijing reduces life expectancy by 15 years

The effects of urban pollution in China are started to get out of hand, and by now, it’s pretty safe to say that they are dealing with a major pollution crisis – the smog in Beijing particularly is so severe you can easily see it from outer space. Now, a new study has concluded that […]

Man-made greenhouse gas is 7,100 times worse than CO2

Chemists at University of Toronto report a new greenhouse gas has been added to the roster - perfluorotributylamine, or PFTBA. Like other compounds in its class, PFTBA is a frighting good heat absorbent but nobody was expecting, however, for it to be 7,100 times more powerful than carbon dioxide in terms of the effects one molecule […]

Trees can capture 50% of particulate pollution cities

Trees planted along a city street could screen residents from sun and noise – but more importantly, they can also protect them from the polluted air. A new study has shown that tree leaves can capture more than 50% of the polluting particulate matter – the main source of urban pollution and a trigger for […]

Great garbage patches in the Great Lakes resemble those in the Pacific

In the 1980s a report described how a ginormous patch of plastic trash was guided by currents and concentrated right in the middle of the Pacific Ocean in an area that some estimated as being roughly two times the size of Texas. Naturally, people all over the world were outraged, but I guess it didn’t last too […]

Lake Erie buried by algae, could become toxic

Overgrowth of invasive algae can have huge detrimental effects both on the environment and on human activities. This is quite clearly observed in lake Erie, where a study published by the National Academy of Sciences documents some serious problems. Farmers and the environment According to Anna Michalak, the study’s co-author and a researcher at the […]
