A study out last week in the top-tier journal Nature told us that non-caloric artificial sweeteners (NAS) may contribute to glucose intolerance by mucking up our microbiomes. That's a serious indictment, since these products are intended to help defend against glucose intolerance, and other ills related to diabetes risk and weight gain.
We must respond to the urgency of drought and loss of biodiversity, and we must promote landscaping that feeds either people or wildlife. We don't have the water or the time to waste on anything else.
As with any promising new technology, voices have risen in opposition to it, and there are some valid concerns.
Looking above at recent temperature anomalies, much of the U.S. is experiencing well above normal warmer temperatures; the eastern Pacific warm spot continues to prevent much rain from reaching California, sending it into further drought.
We're right in the middle of Wilderness Week, and this year it's a special one because we just celebrated the 50th anniversary of the Wilderness Act -- which is still a high-water mark for the protection of our most precious wild places.
Our future is in peril and the changing climate is a key indicator. Scientists warn us that global warming is spiraling out of control which is why we need to see immediate action now. Preserving the Amazon basin is essential for humanity's survival.
We've trekked from coast to coast seeking out the best views this country has to offer (tough work, but someone's got to do it).
These natural infinity pools make swimming pools look tame.

Still an acceptable form of travel in Iceland, hitching has its perks: It's cheap and it makes meeting locals easy (and necessary).
These incredible views, from all over the world, give the Grand Canyon some serious competition.
Looking above at recent temperature anomalies, the jet stream has once again wobbled down into the US, bringing unusually cool but refreshing weather to much of the US as California and Alaska bake.
What's the rush on renewable clean energy? It's connect-the-dots time! Here's my graphic line of connecting dots: 1. Almost all scienti...
There is simply no way we can protect and maintain a beautiful, thriving, natural and rural landscape outside of cities if we continue to spread highways and suburban sprawl across the countryside. Healthy, robust, beautiful cities where people want to live are critical to the protection of nature.
Why does urban biodiversity matter at all? Because according to the UN, for the first time in human history more people are now living in cities than rural areas. The planet is urban. When people experience nature, that nature will be urban too.
As Labor Day approached a couple weeks ago, I took my two boys fishing. There was no blackboard or chalk at the lake; no textbooks or worksheets. And although we weren't in a formal classroom, nature turned out to be a pretty powerful teacher.
