Ready to Burn
Since 2010, an
estimated 66 million trees have died in a six-county region of the central and
southern Sierra hardest hit by the epidemic, the US Forest Service said.
California is in the
fifth year of a historic drought, which officials say has deprived trees of
water, making them more vulnerable to attack from beetles.
Kathryn Phillips,
director of the Sierra Club California, said the die-off from drought should
signal to policymakers the urgency of curbing pollution that contributes to
climate change.
“This is a warning to
all of us,” she said. “We need to cut our air pollution and greenhouse gas
emissions more. We’re on the right path, but we need to accelerate our effort.”
Dogs - What Do With Do Without Them?
Bighorn sheep and mountain goats that tend to congregate on Logan Pass. In Glacier National Park, bighorn sheep and mountain goats have become accustom to human contact and they are literally creating traffic jams on winding mountain pass roads.
…congestion at Logan Pass filled him with
anxiety. Tourists and wildlife don’t mix, and a recent mountain goat study
conducted at Logan Pass showed that the goats are becoming habituated to
people.
They’re spending more time further from the
cliffs and in human company, Biel said, because humans provide a couple of
benefits. First, large groups of people tend to ward off predators. Second,
humans emit a lot of salt, through urine and sweat, which attracts the goats.
Having a dog there could convince them it’s
not as safe as they thought, though Gracie’s job will be driving them off and
stopping, not chasing them. This puts pressure on the wildlife without overly
stressing them, Biel said.
Electrical Energy
Who do has a better idea about the future?
Tesla or Exxon?
Big news today! Tesla Motors issued a public
statement announcing “it’s now time to complete the picture” — in other words,
the company famous for making the fastest electric cars the world has ever seen
wants to buy the country’s biggest private solar energy provider, SolarCity. If
the deal goes through, Tesla Motors will secure a sustainable energy behemoth
comprised of electric cars (Tesla Motors), energy storage (Powerwall) and
energy generation (SolarCity).
“We
would be able to expand our addressable market further than either company
could do separately. Because of the shared ideals of the companies and our
customers, those who are interested in buying Tesla vehicles or Powerwalls are
naturally interested in going solar, and the reverse is true as well. When
brought together by the high foot traffic that is drawn to Tesla’s stores,
everyone should benefit,” the statement reads.
Legal/Illegal – Dead is Dead
“We find that a singular legal ivory sale
corresponds with an abrupt, significant, permanent, robust, and geographically
widespread increase in the production of illegal ivory through elephant
poaching, with a corresponding 2009 increase in seizure of raw ivory contraband
leaving African countries. The sudden
2008 increase in poaching does not correspond with any abrupt and systemic
change in China’s or Japan’s affluence of influence in elephant range states,
as measured by numerous covariates.”
‘Using trade to conserve wild species is a
really complicated’
The report states, “findings demonstrate
that partial legalization of a banned good can increase illegal production of
the good because the existence of white markets may influence the nature of
black markets. Our findings are likely
to extend to markets structurally similar to ivory markets, such as those for
products from other slow-growing, slow-breeding, or low-population density
species like rhinoceroses and tigers.” (©Solomon Hsiang and Nitin Sekar).
George Wittemyer, a Colorado State
University associate professor of fish, wildlife and conservation biology said
in an interview with Princeton University,
“Using trade to conserve wild species is a really complicated social
issue and it’s hard to predict if it will be successful or not. The fact that you’re
dealing with the persistence of a species means that if you make a mistake, and
your assumptions are wrong, the cost can be extinction or large-scale
extirpation. That to me is really important to consider and a paramount
concern.”
