Forests may not help mitigate carbon dioxide pollution thanks to an uptick in CO2 emissions from decomposition
As higher levels of carbon dioxide permeate the Earth's atmosphere, scientists have long counted on forests -- which, as individual trees, grow larger in carbon-rich environments -- to soak up some of the excess.
But after nearly a decade and a half of observing forest ecosystems in controlled settings, scientists now see evidence that elevating carbon levels may cause forests to release as much extra carbon as they absorb.
There are several causes of ocean pollution including oil pollution, marine debris, toxic materials, and ocean dumping and mining. Oil pollution is not only caused by large devastating tanker spills, it is also caused through runoff from land and industrial wastes which find their way to the ocean through drains. Other causes include intensive farming, septic tank, pesticide, animal dung, household waste, water table, waste water, nuclear waste...
Mountaintop's Removal's Effect on Humans and the Economy
There’s a common saying in Appalachia: what we do to the land, we do to the people. Recently, 21 peer-reviewed scientific studies have confirmed the truth of those words. Not only has mountaintop removal permanently destroyed more than 500 Appalachian mountains, but people living near the destruction are 50% more likely to die of cancer and 42% more likely to be born with birth defects compared with other people in Appalachia.
Arctic monitoring stations show carbon dioxide levels are now above 400 parts per million. Carbon dioxide is the chief climate-change gas and stays in the atmosphere for 100 years. Before the Industrial Age, carbon dioxide levels were 275 ppm.
The world's air has reached what scientists call a troubling new milestone for carbon dioxide, the main global warming pollutant.
