Oil Spills Pose Dire Threats to Marine Life
Prime Minister Justin Trudeau says oil pipelines have no place in BC's Great Bear Rainforest. Opponents of the approved Kinder Morgan pipeline expansion to the West Coast and the cancelled Energy East pipeline to the East Coast argue pipelines and tankers don't belong in any coastal areas. Research led by the Raincoast Conservation Foundation confirms the threat to marine mammals in BC waters from a seven-fold increase in tanker traffic is considerable.
After examining potential impacts of a 15,000-cubic-meter oil spill in BC waters on 21 marine mammals, researchers concluded most individuals would be at risk and a few local populations wouldn't survive. Baleen whales, for example, are highly susceptible to ingesting oil because they breathe through blowholes, filter and eat food from the ocean surface and rely on invertebrate prey. Oil residue can stick to the baleen, restricting the amount of food they consume.
Resident and transient killer whales, sea otters and Steller sea lions were most likely to see a drop in population levels from an oil spill. Killer whales are especially vulnerable because of their small populations, low reproductive rates, dietary specialization, long lives and complex social structure. The 76 southern resident killer whales off the BC coast, Canada's most endangered marine mammal, are particularly threatened by oil spills, as well as ship strikes and underwater noise that hinders their ability to feed and communicate.
If Trans Mountain's Kinder Morgan pipeline expansion proceeds and an oil spill occurs, the study estimates it would affect between 22 and 80 percent of these whales' critical Salish Sea habitat. They already face severe chinook salmon prey shortages and other challenges. In court, opponents argued that adding pipeline and tanker impacts to the mix could lead to their extinction.
Following the 1989 Exxon Valdez disaster in Prince William Sound, a unique pod of north coast orcas vanished forever. Nine of the 22 whales died and remaining pod members didn't produce any living offspring.
All marine mammals are vulnerable to oil spills because they surface to breathe. If that happens in a spill, oil can adhere to their bodies, and they can inhale toxic vapors and ingest oil. Marine mammals exposed to oil spills may suffer damaged airways, congested lungs, stomach ulcerations, eye and skin lesions, weight loss and stunted growth. When whales and dolphins surface to breathe, oil can restrict their blowholes and airways. When seals and otters try to clean oil matted on their coats, they ingest it. They also lose heat because spilled oil ruins their natural insulation, so they can die of hypothermia.
Even indirect exposure to small amounts of oil chemicals known as polycyclic aromatic hydrocarbons can have profound toxic effects on animals and fish, particularly the young. Two years after the Exxon Valdez spill, mortality rates in pink salmon eggs were 96 percent higher than pre-spill levels. Researchers estimated that shoreline habitats such as mussel beds could take up to 30 years to recover fully.
Chronic oil pollution from ships traveling off Canada's coasts kills hundreds of thousands of seabirds every year. In the late 1990s, an estimated 300,000 birds died annually off Newfoundland's coast alone.
No technology will adequately clean most oil spills, especially diluted bitumen. Unlike conventional crude, bitumen can sink if spilled in water, according to a 2016 study by the National Academy of Sciences. It also found that current regulations and spill-response techniques can't manage the unique behavior and higher risks of a bitumen spill. Tar balls sink to the bottom or hang in the water column, eluding conventional booms used to contain oil spills.
An Oil Tanker Moratorium Act before Parliament recognizes that BC's north coast ecosystems and local economies must be protected from oil spill risks. BC's new government will argue in its case against the Kinder Morgan pipeline that the federal government failed to evaluate the project's risks to the marine environment—a breach of its obligation to consider the national interest.
It's certainly not in the interests of any marine mammal, especially endangered ones, to add more shipping traffic or increase oil spill risks—nor is it in keeping with our Paris agreement commitments to shift away from fossil fuels. Let's hope that the Kinder Morgan project goes the way of the Energy East pipeline.

‘Companies Should Not Be Allowed to Use Hazardous Ingredients in Products People Use’: Michelle Pfeiffer Speaks Up for Safer Cosmetics
The beauty products we put on our skin can have important consequences for our health. Just this March, the U.S. Food and Drug Administration (FDA) warned that some Claire's cosmetics had tested positive for asbestos. But the FDA could only issue a warning, not a recall, because current law does not empower the agency to do so.
Michelle Pfeiffer wants to change that.
The actress and Environmental Working Group (EWG) board member was spotted on Capitol Hill Thursday lobbying lawmakers on behalf of a bill that would increase oversight of the cosmetics industry, The Washington Post reported.

Scientists at the United Nations' intergovernmental body focusing on biodiversity sounded alarms earlier this month with its report on the looming potential extinction of one million species — but few heard their calls, according to a German newspaper report.
The climate crisis is a major concern for American voters with nearly 40 percent reporting the issue will help determine how they cast their ballots in the upcoming 2020 presidential election, according to a report compiled by the Yale Program on Climate Change Communication.
Of more than 1,000 registered voters surveyed on global warming, climate and energy policies, as well as personal and collective action, 38 percent said that a candidate's position on climate change is "very important" when it comes to determining who will win their vote. Overall, democratic candidates are under more pressure to provide green solutions as part of their campaign promises with 64 percent of Democrat voters saying they prioritize the issue compared with just 34 percent of Independents and 12 percent of Republicans.
President Donald Trump has agreed to sign a $19.1 billion disaster relief bill that will help Americans still recovering from the flooding, hurricanes and wildfires that have devastated parts of the country in the past two years. Senate Republicans said they struck a deal with the president to approve the measure, despite the fact that it did not include the funding he wanted for the U.S.-Mexican border, CNN reported.
"The U.S. Senate has just approved a 19 Billion Dollar Disaster Relief Bill, with my total approval. Great!" the president tweeted Thursday.
