This overpass helps bears cross a highway in Canada.
Bear hair study in Banff proves animal highway crossings work
For three years, researchers from Montana State University spent their summers collecting bear hair. The samples, collected on both sides of the 50 mile stretch of the Trans-Canada Highway that cuts through Banff National Park, prove what the researchers had suspected: wildlife underpasses and bridges were helping enough bears move back and forth across the highway to keep the populations healthy.
The Trans-Canada Highway stretches nearly 5,000 miles acrowss the country, rolling through each of the nation’s 10 provinces and connecting the Atlantic and Pacific coasts. The 100 miles that pass through Banff National Park is a blip in the entire stretch of highway, but a potentially deadly obstacle for the wildlife that live in the park. Demand for a bigger, faster road system prompted a widening of the highway in the 1990s. During construction, engineers lined the highway with fencing and built underpasses and bridges for animals to cross, with the theory they would reduce collisions and provide animals safe passage. However, the decision was controversial as there was little data to backup the hunch.
Candidates for mayor should promise to extend Bloomberg’s environmental record.
The candidate who succeeds him will have a lot of solid plans and ambitious goals to work with. The challenge will be to fulfill and expand them, despite the day-to-day emergencies and distractions that tend to blur and constrict worthy visions over the long term.
On this front, Christine Quinn looks good. Her tenure as City Council speaker entitles her to share credit for Bloomberg-era policies like the law requiring the city to reduce carbon emissions 30 percent by 2030 and the one requiring large buildings, vast emitters of greenhouse gas, to audit their energy use to increase efficiency. Expanding river ferry service, maintaining parks, curbing the use of sooty fuel oil — on these and other issues, she has a record to run on.
The system delivers your online purchases to the rail stations and buses that you’ve used in the last 21 days.
If you have not used Metro or regional transit in that time frame, you will need to touch your card to a SmarTrip® target at a faregate, fare vending machine or bus farebox to let the system know where to deliver your products. You must then wait one business day if you touched a target at a faregate or fare vending machine or two business days if you touched a target at a bus farebox.
If you try to pick up your product at a rail station or bus, and it’s not available for you yet, please try again at the same rail station or the same bus line the next business day.
The system can store up to four product load instructions at a time for a single smart card. After those four products have been loaded to your card, the next group of up to four product load instructions will be issued and will be available to load to your smart card.
In other words, if your “SmarTrip” Metro Card doesn’t work after adding money to it, “Meh, just go away and come back tomorrow. Might work. Might not.”
This really is an answer in Washington, DC’s Metro FAQs section. My Metro Card is connected to an account online. I added money to the card thinking - silly me - that I could use the Metro Card at the metro station. Nyyyyyyyope!
The U.S. Government Accountability Office (GAO) audits the Federal Government. Recent analysis concluded that Obama (well, actually “the Federal Government”) should aggressively fund infrastructure projects, including electricity grids, water supplies, and transportation networks.
The aim is to make the nation’s infrastructure more resilient to climate change (e.g., stronger and tougher), thus saving nation’s taxpayers billions in emergency spending.
Politicians uninterested in helping fix the situation, leaving repairs to emergency funds. And endangering the public…
NPR’S Scott Simon introduces the topic (on the audio version) with this somber revelation: “[C]hances are 1 in 9 that a bridge you drive over has been deemed structurally deficient, or basically in bad shape, by the federal government.” Worse yet, “there is no consensus on how to tackle the problem or pay for proposed solutions”.
Belizean police are investigating a construction company that has destroyed most of one of the largest Mayan pyramids in the Caribbean nation to make gravel to dump on village roads, according to reports from the Caribbean.
Archaeologists and a local TV station witnessed the destruction Friday as bulldozers and excavators continued to demolish the 60-foot-tall main temple at Nohmul — “great mound” — one of the tallest structures in northern Belize, along the Mexican border in the Yucatan Peninsula.
"We can’t salvage what has happened out here," John Morris, of the Institute of Archaeology, told 7 News Belize. "It is an incredible display of ignorance. I am appalled." A news crew was threatened by a man with a machete as dump trucks hauled away rock and limestone from the temple, which has been "whittled down to a narrow core," the TV station said.
A Caterpillar excavator was photographed tearing down what was left of the limestone-rich ruins. “It’s like being punched in the stomach, it’s just so horrendous,” Jamie Awe, head of the institute, told the Associated Press. “These guys knew that this was an ancient structure. It’s just bloody laziness.”
The pre-Colombian site is about 2,500 years old and consists of twin ceremonial clusters surrounded by 10 plazas and connected by a raised causeway. Mayans used stone tools to quarry the rock and build the complex by hand. An estimated 40,000 people are believed to have lived there between 500 and 250 BC.
More of these incidents to come in the years ahead as population growth outweighs the need to protect resources.
Sinkhole in Chicago neighborhood swallowed three cars this morning. As usual, this one was caused by a water main break. The water eroded the soil and rock under the road, creating a void and ultimate collapse. We’ll hear a lot more of these incidences in the coming years. America’s infrastructure is in rough shape, and water, sewer, and gas lines average close to 50 years old. Replacements costs are extremely high - most cities wait for a break to happen before replacing pipes, which is more expensive and dangerous over time. But, cities around the country are deferring maintenance due to a dwindling tax base. Via NBC.
