As the National Park Service enters its second century, it made me consider: What is the impact of millions of vehicles on our nation’s “best idea” and how does it compromise our experience of these grand places? What is being done to minimize auto traffic in national parks? Which parks are accessible via alternative transportation?

Are you ready for mechanized vehicles on every wilderness trail in the United States? That's what you'll get if a deceptive piece of federal legislation becomes law. Portrayed as a “modest” proposal for mountain bike access, the legislation is a Trojan horse that would throw open all designated wilderness areas to bikes and prevent federal land managers from later excluding them.

Is organic-based farming merely a niche model of agriculture that is not capable of feeding the global population? Or does it have a major role to play?

In addressing these questions, it would be useful to consider a selection of relevant literature to see what it says about the role of organic farming, how this model of agriculture impacts farmers and whether or not it can actually feed the global population.

In the hills near Hollywood, a lone mountain lion is challenging us to prove that humans and wildlife can coexist.

Despite the EPA's claims, information on dangerous synergistic effects is publicly available. In fact, the agro-giants collected it themselves

The amount of meat humans eat is immense. In 1965, 10 billion livestock animals were slaughtered each year. That number is now over 55 billion. Factory farming is the fastest growing method of animal production worldwide. While industrialised nations dominate this form of farming, developing countries are rapidly expanding and intensifying their production systems.

Violence on the farm

A new virtual reality film project by Animal Equality shows the public how a factory farm operates. The film focuses on how pigs live out their lives from birth to death – from the perspective of a pig. It is clear that it is not just the pig’s final death that is brutal but its whole life

A French man died last month and five others in the same clinical trial were hospitalized after they took an experimental drug. The drug had been deemed safe for humans after having been tested on chimpanzees in preclinical trials.

The National Institutes of Health’s recent decision to end federally supported chimpanzee experimentation could prevent future fatalities like this by promoting more human-relevant research methods.

Twenty of those government-owned chimpanzees currently housed at a testing laboratory in San Antonio, Texas, are next in line to be transferred to a sanctuary. As the use of chimpanzees in medical experiments draws to a close, it’s important to examine the superior, nonanimal research methods that will benefit patients.

Ted Greiner shows why 107 nobel laureates are dead wrong.

Despite the claims of it's advocates, Golden Rice is still far from being ready for the market, is completely untested, and unnecessary.
