Rhino Shot Dead by Poachers at French Zoo

A young white rhino was killed after being shot in the head three times by poachers who broke into the Thoiry Zoo in Paris Monday night. Poachers de-horned the 4-year-old rhino, named Vince, and left alive two other white rhinos, 37-year-old Gracie and 5-year-old Bruno. They left part of Vince's second horn, leading local police to believe they were ill-equipped or interrupted. The poachers are still at large.

Large Sewage Spill in Mexico Flows North of the Border for 17 Days

A spill that originated in the Tijuana River in Mexico flowed north of the border, releasing 143 million gallons of sewage for 17 days. The spill was caused when a sewage pipe under rehabilitation ruptured at the juncture of Mexico's Tijuana and Alamar rivers. While three-quarters of the Tijuana River watershed is located in Mexico, it drains into the Pacific Ocean near Imperial Beach, California.

"It's horrible. Everybody is complaining about it. People are really upset with the smell," Imperial Beach resident Lidya Morales told FOX 5.

"This is the worst spill we've had in over a decade," Imperial Beach Mayor Serge Dedina exclaimed.

After receiving complaints about the odor, Dedina sent a written inquiry to the U.S. Section of the International Boundary and Water Commission (IBWC). The agency then provided him a report regarding the spill.

"It's a major communication failure. It's obviously something they knew for a very long time," Dedina said. "Border authorities charged with managing sewage infrastructure and reporting these spills must do better and be held accountable for this act," the mayor said as he called for the resignation of IBWC chief Edward Drusina for his poor management of cross-border wastewater issues.

"It's outrageous that we have sewage spills of this magnitude occurring under the watch of the IBWC, and it's equally outrageous there aren't proper procedures in place to notify the public when sewage releases occur," Matt O'Malley of the San Diego Coastkeeper told EcoWatch.

"This is not just an environmental failure—it's a failure to protect the public health of those who live, work and recreate along the Tijuana River, Imperial Beach and beyond. The circumstances surrounding this spill and the failure to timely release information related to it should be investigated and prevented from happening again. Officials on both sides of the border must make sewage infrastructure in the region a top priority."

Coincidentally, local South Bay beaches were already closed due to sewage run-off from the recent rainstorms. A 2012 sewage spill caused by a similar Tijuana pipe breakage, which spewed almost 3 million gallons of sewage into the Pacific, had closed Imperial Beach for several days.

This highly polluted river has many sources and is a persistent issue, which has cost the U.S. and Mexico hundreds of millions of dollars. Since the 1990s, the U.S. and Mexico have created programs to cooperatively address the issue, including the Minute 320 accord, which established a "general framework for binational cooperation" between the countries "on transboundary issues in the Tijuana River Basin."

Some areas in Mexico, including Tijuana, currently lack sufficient sewage infrastructure and garbage collection, and some residences do not have any form of plumbing. Along with population growth, this "has resulted in large amounts of human and industrial sewage, plastics and other forms of garbage accumulating in the river," Western Washington University's Huxley College of the Environment explained. Factories in the Mexican state of Baja California also contribute to pollution in the Tijuana River, KCET reported.

The river is bisected by the current U.S.-Mexico border wall, which President Trump plans to expand. The 2008 reinforcement of this wall "razed entire mountaintops and used the earth to fill in gulches and canyons," increasing erosion and contamination issues, KCET said.

"Significant improvements in the arena of wastewater treatment in recent years have improved water quality on both sides of the border," the Surfrider Foundation said. Unfortunately, storm water still brings substantial amounts of pollution into the Tijuana River Watershed. Their "No Border Sewage Campaign," which started in 2008, seeks to address this issue through outreach, networking and education.

57 Snow Monkeys Euthanized for Carrying 'Alien' Genes

The Takagoyama Nature Zoo in the city of Futtsu, Japan euthanized 57 snow monkeys who were found to have hybrid genetic make-ups. The zoo mistakenly believed all 164 of its resident primates were pure Japanese macaques (Macaca fuscata), which are endemic to Japan. When the zoo discovered through DNA testing that 57 of them were actually of a hybrid breed, rhesus macaque (Macaca mulatta), which is common throughout Southeast Asia, they culled the hybrid monkeys.

In 2013, Japan's environmental laws were revised to make holding or transporting invasive species including hybrids illegal, in an attempt to protect the indigenous environment and native species. Culling of rhesus macaque is allowed under this law, which designates them as an "invasive alien species."

An Office for Alien Species Management official said the culling was unavoidable because the hybrid species might escape and reproduce in the wild, BBC reported.

The monkeys were culled through lethal injection over the course of about a month, ending in early February. The zoo operator then held a memorial service for the hybrid monkeys at a local Buddhist temple.

Questions remain as to whether other steps could have been taken such as sterilization, IFL Science pointed out. Transplanting the common hybrids into another region may have also been a possibility; they are native to Burma, India, Thailand, Afghanistan, Vietnam, Bangladesh, Pakistan, Nepal and China.

"There are many zoos in the country, which rear animals that became classified as invasive species after the law was created," an Environment Ministry official said, according to Phys.org. Zoos can apply for exceptions to keep the hybrid species.

"Preventing exposures to foreign animals is very important," said Tomoko Shimura of the Nature Conservation Society of Japan. The Chiba prefecture where the zoo is located has been culling the hybrids since 2005.

Japanese macaques are brown with white faces and are the only indigenous primate in Japan and most northern living nonhuman primate on Earth. They are also known as snow monkeys and have developed a hot tub culture by warming themselves in hot springs. The area around the zoo is designated as their wild habitat.

In the U.S., concerns over protecting native species' genes have arisen in relation to genetically engineered (GE) salmon produced by AquaBounty, Inc. and approved by the U.S. Food and Drug Administration in 2015.

Fears relating to GE salmon include the possibility they will mate with native species, introduce new diseases and/or compete for resources and habitat.

Ready to Escape Into This Magical Treetop Orb?

Free Spirit Spheres resort in British Columbia knows there's nothing quite like being in an orb in a tree canopy. They invite you to experience an enchanted rainforest vacation in a spherical suspended treehouse. The year-round, adult-only resort on Vancouver Island features three hanging handmade orbs, which you can rent for $175 per night.

"Normal buildings that we're in are all about separation ... when you step into a sphere there is no separation. There's only one wall," owner Tom Chudleigh told Arbutus RV Island Adventures. Chudleigh has a background in engineering and spends three years personally building each sphere.

The three rentable orbs are called Eve, Eryn and Melody and each is accessed by a spiraling staircase. Chudleigh also has his own office sphere, called Gwyn. The orbs weigh about 1,100 pounds and are each tied to three separate trees. A strong breeze or the movement of an inhabitant causes them to sway.

The sphere interiors hold drop-beds, workspaces, sinks and round windows, Curbed explained. Each has its own electric composting toilet outhouse and a shared bathhouse with a sauna. There are several restaurants within three to 15 miles from the resort.

Eve was the prototype and is 9 feet in diameter. Next came Eryn and then Melody, with 10.5-foot-diameters. Melody has scales from Beethoven's Ode to Joy painted on it. Eve is best suited for one occupant and Eryn and Melody can accommodate two adults.

"There's a magic about these spheres," that comes in part "from the love and intention Tom puts into each one," says Kait Burgan of Arbutus RV Island Adventures. Free Spirit Spheres is about 35 miles north of the city of Nanaimo on Vancouver Island, between Qualicum Beach and what is locally known as "lighthouse country."

Free Spirit Sphere's hopes this floating oasis in the canopy of the coastal forest will "provide a venue for people to enjoy exceptional experiences while dwelling in a natural forest environment." Chudleigh also wants to build new spheres and is seeking new spaces and potential partners that can enable him to do so.

Wind Power Sets New Record: Briefly Provides Majority of Electricity for 14-State Grid

On the morning of Feb. 12, wind power provided 52.1 percent of the electricity for the 14-state grid known as the Southwest Power Pool (SPP). This is a significant milestone for wind, which has never before provided a majority of power for any U.S. grid, according to SPP.

SPP is responsible for 60,000 miles of power lines running from North Dakota and Montana to Texas, New Mexico and Louisiana. Wind generates about 15 percent of the electricity in the SPP region and is third behind coal and natural gas.

The February 52.1 percent wind-penetration beat the April 2016 record of 49.2 percent. Wind-penetration is a measure of the grid's electrical total load served by wind.

"Ten years ago, we thought hitting even a 25 percent wind-penetration level would be extremely challenging and any more than that would pose serious threats to reliability," Vice President of Operations Bruce Rew said in an SPP statement. Rew explained SPP can now reliably manage more than 50 percent wind-penetration and that they have not yet reached their "ceiling."

American Wind Energy Association's Greg Alvarez celebrated the news in a blog post. "Records like these resonate, because they demonstrate wind energy can play a key role in an affordable, reliable, diversified energy mix," he said. "That creates a stronger system, and helps keep more money in the pockets of families and businesses."

In the early 2000s, SPP wind power provided less than 400 megawatts (MW) and now provides 16,000 MW. A single MW is usually able to power around 1,000 homes, Climate Central explained.

SPP has achieved this wind power milestone because of its enormous power generation footprint, which covers nearly 550,000 square miles. If the upper Great Plains is not windy one day, SPP "can deploy resources waiting in the Midwest and Southwest to make up any sudden deficits," Rew said.

Since 2007, SPP has spent more than $10 billion on high-voltage transmission infrastructure with a focus on connecting "rural, isolated wind farms to population centers hundreds of miles away," the organization said.

In 2015, 39 states harnessed electricity from utility-scale wind projects, according to the U.S. Energy Information Administration. Texas, Oklahoma, Iowa, Kansas and California produced the most wind energy and about 50 percent of the total for U.S. wind production.

In 2016, wind power was the largest U.S. source of renewable electric capacity and is now the country's fourth-largest energy source.

This City Is Giving Residents $1,200 Toward Buying an Electric Bike

The city of Oslo, Norway is offering grants to help its citizens partially pay for electric cargo bikes through its Climate and Energy Fund. Each grant covers up to $1,200 or 25 percent of an electric cargo bike purchase, which can cost from $2,400 to $6,000.

The funds could potentially put "500 to 1,000 electric cargo bikes onto Oslo's streets" for individuals, businesses and organizations, City Lab reported.

"Unfortunately, subsidy for private individuals" is no longer available, but "it is still possible to apply for funding for pilot projects under the auspices of condominiums, cooperatives, organizations or companies," the Oslo Council bike grant application page states.

Oslo offers this grant partly because of the city's growing issues with air pollution, which also prompted a January ban on diesel vehicles. Similarly, in late 2016, Paris imposed driving restrictions and provided free public transportation.

"Despite considerable improvements in past decades, air pollution is still responsible for more than 400,000 premature deaths in Europe each year," according to The European Environment Agency, which described air pollution as a persistent problem throughout Europe.

In 2016, Oslo carried out a similar initiative to partially pay for up to 20 percent of the cost of an electric bike. These funds were used in full. This program received criticism when it was discovered that some of the electric bike recipients were among Oslo's wealthiest citizens or were living outside of Oslo.

Oslo's numerous hills and harsh weather conditions have also been called deterrents to electric bike programs, yet the city appears to continue to pursue green solutions at every front. In 2015, Oslo became the first capital city to ban investments in fossil fuels. Additionally, electric cars outsell conventional vehicles in Oslo and the city has dedicated $1 billion to a bike infrastructure fund, reported City Lab.
