The effects of Sandy's destruction linger in many areas where it made landfall, but the storm has had wider-ranging impacts, including influencing how we predict and prepare for future storms.

MSNBC is far from a lonely native advertising bystander, joined in the hustle by the likes of The Huffington Post, BuzzFeed, The New York Times, the AP and others. A case in point: On Sept. 10, HuffPost Green ran a native ad article titled "8 Cities Embracing Natural Gas," sponsored by ANGA.

Some 200 million people around the world are increasingly threatened by toxic wastes such as lead, mercury, chromium and radioactivity according to a new report listing the ten most dangerous threats in the world.

Violence, uncertainty and unrest go hand in hand with food, water and energy scarcity. Probably no Americans are more acutely aware of this fact than the men and women we have sent into harm's way over the last 20 years.

Despite the presence of "know nothing" deniers of climate science in the United States Congress, the causes of the climate crisis and the solution to that crisis are known and need to be made an urgent priority in the nation's capital.

Colorado Public Radio's Ryan Warner and ProPublica's Abrahm Lustgarten fact checked a new set of ads sponsored by Coloradans for Responsible Energy Developments. The results of their analysis dealt a blow to oil and gas advocates.

We need to listen to the surviving first cultures. They are a vehicle for connecting modern humanity to nature and wisdom.

Fighting for our health and environment is about tackling difficult challenges such as our continued dependence on fossil fuels. We cannot let ourselves get waylaid by industry attempts to undermine our spirit with false claims of "inevitability."

We must allow the recovery of wolves to continue under the Endangered Species Act; the job is far from done. Bringing back wolves restores predator-prey interactions that preceded humans and shaped the wild special places that we all love today.

Buy your toilet paper made from post-consumer content, get your food as organic and local as you can (urge your local farmer to trade in that gas guzzling pick-up for something more climate friendly) and pray for a miracle.

Killing bugs has become a modern-day pastime. Just scan the products on offer at your local supermarket. There's anti-bacterial this and antiseptic that. Is our antimicrobial obsession making us sick?

Why do wildfires continue year after year? Can't we do something to better manage fires? To further compound matters, wildfire reports or news segments are likely to include terms the majority of us are unfamiliar with -- making these questions that much more difficult to answer.

Lois Gibbs did not shrug her shoulders and say "I don't have the time or what difference would it make?" when calamity struck her and her neighbors. It's easier than we think to start turning things around. We have to believe so and show up.

No one seems to ask why we need cheap food in the first place. The simple answer is that cheap food helps to keep wages down.

There are also some very pushy, obnoxious dogs out there (Bodhi, when he first came to us, for example), and yes, even aggressive and severely aggressive dogs. But when we put those dogs in a box and slap a label on it (Red Zone! Beware!), we do them a disservice.

We have a vague sense that species are dying, and that GMOs might be less safe than their developers claim, but so far the grocery store keeps supplying food, and we have other things to worry about.

Like the vested interests Villaraigosa referenced, industrial agriculture is holding fast to the methods of its poisonous assault. But these are issues we can choose to fight at the supermarket. Or at the farmer's market.
