MNN week in review montage

Our picks for the week of Sept. 5-11: 

• America's national parks are a good indicator of the country's economic health — and not in a good way.

• This week's destination is farther afield than usual and it will stretch your imagination, too. Come along with us to Cambodia.

• "Fate of Nature": Charles Wohlforth's new book dares to suggest that we aren't destined to ruin the Earth and ourselves.

• Ken Edelstein is floored by BP's chutzpah. It takes audacity to remain silent about a toxic release at a Texas refinery while you're spending tens of millions on PR to soften the blow of the Gulf oil spill.

• Leash? Check. Plenty of food and water? Check. That's a good start for your dog's must-have list, but here's what you need for a pet first aid kit.

• Worried about the mosquitoes you just swatted away? You should be. From dengue fever to West Nile virus, mosquitoes seem to be getting better at smuggling diseases into the U.S. 

• This week in Ecollywood, we check on Meredith Vieira's garden and much more. 

• Humans have no shame when it comes to saving animals. Here are 10 odd — but effective — methods for protecting endangered species.

• And finally, a sign of the times: The last major U.S. factory making incandescent light bulbs is closing.

Plus: Don't miss the week in photos, including the image from Chile (above) of astronomers shooting a laser at stars.
