Horses threaten panda population
March 26, 2014 07:27 AM - Editor, ENN
Pandas rely upon a specific diet and habitat. They typically live far away from human populations on gently sloping hillsides. Their diet is made up of exclusively bamboo. China invests billions to protect its panda habitat and conserve the 1,600 remaining endangered supported by this habitat. China has instituted many conservation programs limiting the timber harvesting that had greatly threatened this habitat. But now it seems that with the timber harvesters are under control the bamboo is still being devastated before the pandas can get it.
COLLEGIATE CORNER: Humanity of factory farming
March 25, 2014 02:01 PM - Jake Bucks, Class of 2015, Wakefield High School
Most omnivores like bacon, but I say omnivores because not every human is an omnivore. Have you ever thought to yourself what was the process this bacon went through? Well if you have, it was not a fun process for that pig. Farming has helped humans advance in size, without the farming innovations created through the industrial revolution, humans would have never had the resources to make such a huge population.
EPA and Army Corps bring clarity to Clean Water Act Expansion proposal
March 25, 2014 01:38 PM - ENN Staff
In a joint document the EPA and the Army Corps of Engineers released a proposed rule to clarify protections provided by the Clean Water Act. Following Supreme Court decisions in 2001 and 2006, there has been much confusion about definitions within the Act and applicability. The proposed clarifications will enhance understanding for industry, agriculture, local government officials and the public as it relates to protection of streams and wetlands that form the foundation of the nation's water resources.
Future cost of water is no small change
March 25, 2014 12:22 PM - Dr. Lynn A. Wilson, Kaplan University
Water scarcity was, until recently, considered by most of the developed world to be like James Hilton's Lost Horizon: "far away, at the very limit of distance." However, the convergence of aquifer depletion from increasing agricultural, industrial and municipal water use with more frequent and intense extreme weather events creates an urgency to develop new, reliable sources of fresh water to "drought-proof" communities through a combination of desalinization technologies, water recovery and reuse programs and PPP (public private partnerships). The race is on to provide fresh water to satisfy ever-increasing human demands. In order to make responsible decisions, changing conditions require rethinking water policy and distribution.
World’s river systems: Stressed OUT
March 24, 2014 02:16 PM - Robin Blackstone, ENN
According to the World Resources Institute (WRI) many, if not most of the world’s rivers are stressed. Determining a systems water stress is based upon measuring the ratio of total water withdrawals to the available renewable supplies within the catchment area. Rivers are an indispensible resource for our communities and ecosystems and we are hugely dependent upon them for agriculture, industry and our natural systems. A stressed river system can severely threaten regional water security and economic growth, and potentially contribute to political instability—especially in the absence of an adequate water-management plan.
Chernobyl: thirty years hence...
March 24, 2014 09:26 AM - Rachel Nuwer/Smithsonian, Ecologist
It's not just people, animals and trees that suffer from radiation at Chernobyl, writes Rachel Nuwer, but also decomposer fungi and microbes. And with the buildup of dead wood comes the risk of catastrophic fire - which could spread radiation far and wide. Nearly 30 years have passed since the Chernobyl plant exploded and caused an unprecedented nuclear disaster. The effects of that catastrophe, however, are still felt today.
Wetlands and methane emissions
March 23, 2014 09:59 AM - Tim Radford, The Ecologist
Scientists think the amount of methane emitted to the atmosphere from freshwater ecosystems will increase as the climate warms, reports Tim Radford. And that will trigger further warming. This highlights another mechanism by which the global carbon cycle may serve to accelerate rather than mitigate future climate change. British scientists have identified yet another twist to the threat of global warming. Any further rises in temperature are likely to accelerate the release of methane from rivers, lakes, deltas, bogs, swamps, marshlands and rice paddy fields.
Nissan LEAF drivers save big!
March 22, 2014 07:19 AM - Staff ClickGreen, ClickGreen
Drivers of the world’s best-selling electric car, the Nissan LEAF, are edging towards the milestone of clocking up 1 billion kilometres of low-cost, low-carbon motoring. Owners of more than 100,000 Nissan LEAFs worldwide have now collectively saved over £50 million through cheaper fuelling costs and are responsible for removing 204,000 tonnes of potential CO2 emissions from the environment.
Road to environmental destruction
March 21, 2014 11:40 AM - ENN Editor
Roads are considered connectors of human development providing opportunities for economic success and communication but the flip side of this network is that it has also brought enormous destruction to our fields and forests. With forest destruction comes increased human development and ecological degradation. Recent mapping and modeling has been done to document and measure forest destruction in an initiative by the Ames Research Center of NASA and ENN affiliate, Mongabay.
The omni-benefits of regenerative pasture
March 21, 2014 11:04 AM - Natasha Giddings, Ecologist
Managing grasslands in a way that mimics natural grazing by wild animals improves water infiltration, reduces erosion, conserves nutrients, reduces costs, raises production and increases profits, writes Natasha Giddings. Why isn't everyone doing it?
