As the human population grows, we have more and more of an impact on surrounding life. These animals have become endangered, and it's up to us how much longer they have on our planet.

The principal cause of the shrinking population of monarch butterflies is loss of habitat in their U.S. breeding grounds, scientists say in a study published in the Journal of Animal Ecology.
Planting milkweed in the south and central United States would provide the largest immediate benefit,"
"Police in Mombasa today morning impounded ivory worth millions of shillings.The ivory, which consisted of some 230 pieces of elephant tasks weighing three tonnes were found in a motor vehicle yard in Tudor estate.
"Police, who were acting on a tip-off, conducted a night operation which saw the manger of the yard Abdulkalim Sadiq, arrested. Mombasa police boss Geoffrey Mayiek, who led the operation, said the consignment was packed in sacks ready for shipment out of the country via the Mombasa port.
"Police and Kenya Wildlife Services officers suspect the tusks were from at least 114 elephants from different national parks in the country including the Tsavo national park."

President Obama recently unveiled his plans for America to cut its CO2 emissions 30% compared to 2005 levels by 2030 "to limit warming below the 2˚C ceiling agreed by countries", a plan that Al Gor...
The cuts the EPA will administer do not seem to be large enough to make a real difference. Perhaps they will be contagious and spread to other industries.
For thousands of years, black wolves have roamed the snow-covered islands of southeast Alaska's Alexander Archipelago. But even in this remote stretch of more than 1,000 islands and glaciated peaks, Alexander Archipelago wolves have been no match for industrial logging, road building and overharvest.

"The numbers of known species with very small ranges are increasing quickly, even in well-known taxa. They are geographically concentrated and are disproportionately likely to be threatened or already extinct. We expect unknown species to share these characteristics. Current rates of extinction are about 1000 times the background rate of extinction. These are higher than previously estimated and likely still underestimated. Future rates will depend on many factors and are poised to increase. Finally, although there has been rapid progress in developing protected areas, such efforts are not ecologically representative, nor do they optimally protect biodiversity."
Another new study, this one appearing in Science, also concludes that current extinction rates are about 1,000 higher than anything Earth has experienced before the arrival of Homo Sapiens.
May 2014 – ECOLOGY – Species of plants and animals are becoming extinct at least 1,000 times faster than they did before humans arrived on the scene, and the world is on the brink of a sixth great extinction, a new study says.
Repeated analyses of extinction rates confirm the current emergency. Now is the time for every citizen of Earth to come to nature's aid. We know what's killing our plants and animals. It's time to stop,
Abstract: In 1997, the global value of ecosystem services was estimated to average $33 trillion/yr in 1995 $US ($46 trillion/yr in 2007 $US). In this paper, we provide an updated estimate based on updated unit ecosystem service values and land use change estimates between 1997 and 2011. We also address some of the critiques of the 1997 paper. Using the same methods as in the 1997 paper but with updated data, the estimate for the total global ecosystem services in 2011 is $125 trillion/yr (assuming updated unit values and changes to biome areas) and $145 trillion/yr (assuming only unit values changed), both in 2007 $US. From this we estimated the loss of eco-services from 1997 to 2011 due to land use change at $4.3–20.2 trillion/yr, depending on which unit values are used. Global estimates expressed in monetary accounting units, such as this, are useful to highlight the magnitude of eco-services, but have no specific decision-making context. However, the underlying data and models can be applied at multiple scales to assess changes resulting from various scenarios and policies. We emphasize that valuation of eco-services (in whatever units) is not the same as commodification or privatization. Many eco-services are best considered public goods or common pool resources, so conventional markets are often not the best institutional frameworks to manage them. However, these services must be (and are being) valued, and we need new, common asset institutions to better take these values into account.
(Warning: This post contains a graphic image) Atlantic bluefin tuna is tasty. So tasty, in fact, that the fish is also endangered. There are now only half the number of Atlantic bluefin tuna in the sea that there were in 1970. That's despite rules set by governments around the world that have restricted tuna fishing, with the goal of leaving enough of them...
Photographer and pilot Alex MacLean wanted to learn more about the Keystone XL pipeline, which if approved will carry oil from Canada to the Gulf of Mexico, so he decided to take pictures from above of the tar sands that will supply oil to the proje...
In May, the White House released the National Climate Assessment, a report written by a committee of 60 scientists that assessed risks from man-made climate change including rising seas, extreme heat and dropping water supplies. Separately, two science papers released in May reported that the global sea level will rise at least 10 feet, accelerating to a dangerous pace after the next century. The reports sparked some much-publicized comments by politicians and pundits, making climate change a hot issue in elections this fall in some states. Here’s a summary of some of our recent fact-checks on climate change. We ...
