With the attention on first generation corn ethanol fading, the next big thing on the sustainable fuel horizon is nonfood biofuel crops. Within that category, inedible weeds are taking a front-row seat due to their relatively low demands on water, pesticides, and herbicides, and their reduced need for tilling and other mechanized soil prep. Some weeds with biofuel potential can also thrive on contaminated soils, absorbing and cleaning pollutants in a process called phytoremediation.

Impassioned editorials are calling for the restoration of The Angeles National Forest but what is the political cost of restoring the environment at a pace faster than nature’s, or of failing to do so?

Many thousands of Kenyans are enduring a severe drought, caused in part, it is believed, by cutting down ancient forests.

Australia’s wild camel population is out of control. An estimated 1 million roam the outback, destroying fragile ecosystems, fouling water holes, and causing a threat to endangered wildlife.
They are Australia’s largest invasive species, and the government is spending $19 million AUD to deal with the excess population of desert dwellers. The country’s solution? Slaughter them from helicopters and serve them up as camel burgers, camel pies, camel sausages, camel steaks, and camel mince.

Controversial proposals by the Australian government would mean shooting more than 650,000 camels from helicopters - and even making camel burgers.
Camels have become a problem in Australia’s remote Outback.
There are now about a million camels, and the population doubles every nine years. The animals were introduced to the Australia in the 1840’s by explorers who relied on them to journey through the desert. But now, camels are competing with livestock for food - and are apparently scaring people by destroying water pipes and bathrooms as they search for water.
Sky News has reported that the Australian government believes the population needs to be culled by two thirds - and they have a budget of $19 million AUD to take care of the situation.
That means the mass killing of more than 650,000 camels.
As climate scientists scour the Earth’s surface looking for indications of climate change impacts, freshwater lakes and reservoirs are becoming the sentinels of choice for many investigations. Although they make up a small percentage of the planet’s surface area, such bodies of water–small to large–are providing clues to past climate fluctuations, as their sediments and “catchments” (the total chemical and biological materials that result from the presence of the body of water) often record ancient climate impacts, and offer indicators [...]
In another addition to the “secret life” (and mysterious abilities) of plants, a recent study demonstrated that a native, perennial plant, The Great Lakes Searocket (Cakile edentula), responds to the presence of related and non-related plants differently.

A fast growing invasive seaweed that grows up to an inch a day is turning San Francisco Bay into a ‘jungle’ of kelp.
When you think of wakame (if you do at all), you’re probably imagining miso soup or a macrobiotic diet, but this variety of kelp (Undaria pinnatifida) is one of the world’s worst invasive species. Native to Japan, China, and Korea, wakame was found to be inhabiting New Zealand about 20 years ago, and recently has been making itself at home in coastal areas of Europe. San Francisco Bay is its latest victim, and the alien seaweed is posing a threat to native species there.

The last time you visited an aquarium, you probably saw one. With their zebra-like stripes, multiple spines, and elaborate fins, they’re quite beautiful and incredibly distinctive. But red lionfish are also voracious carnivores that breed like rabbits and are poisonous to boot. And they’re invading the coastal waters of the Atlantic Ocean.
