NASA Mapping Coral Reefs
Through technology we can measure the damage and pinpoint the causes, but do we have the will
through politics and statecraft to fix the damage and put lasting cures in
effect?
Nasa and top scientists from around the
world are launching a three-year campaign on Thursday to gather new data on
coral reefs like never before.
Using specially-designed instruments mounted
on high-flying aircraft, the scientists plan to map large swaths of coral
around the world in hopes of better understanding how environmental changes are
impacting these delicate and important ecosystems.
The researchers hope to discover how
environmental forces including global warming, acidification and pollution
impact coral reefs in different locations by creating detailed images of entire
reef ecosystems.
Yellowstone’s Raptors Need More Study
Although this year’s study of golden eagles
was put together on a shoestring budget, Smith is hoping to extend the work for
at least one more season.
More information will help the scientists
reach a better understanding of why so many of the eagles are using this high
mountain landscape, as well as establish a point of reference for any future
studies of the big raptors as Earth’s climate changes.
“Golden eagles need to be on the lips and
minds of visitors,” just like other wildlife in Yellowstone, Smith said. “If
people know about them, conservation follows. If people don’t know about them,
nobody cares.
What Good Are Zoos?
Genetic
diversity is critical to a species survival in the wild. Programs like this at the San Francisco Zoo are critical in insuring diversity.
The pack is part of a captive breeding
program to contribute to the genetic diversity—and therefore the survival—of
wolf populations that have been reintroduced to their historical ranges in the
southwestern U.S. and central Mexico.
“There’s a lot of talk about animal reintroduction
into the wild, but it’s not as common as the layperson thinks,” says David
Bocian, Vice President of Animal Care at the San Francisco Zoo.
Genetic diversity is a major challenge to
such programs, continues Bocian. The more narrow the gene pool, the more vulnerable
the population.
“If they aren’t adaptable to adjust to those
curve balls that nature throws at them,” he says, “they’re not going to
survive.”
Plastics: Mans Benefit and Natures Bane
“I want to
say one word to you….plastics!”
Recovering and repurposing plastic waste from the ocean. Several companies
have focused on dealing with ocean trash in creative ways.
Scientists estimate that more than 5 million
pieces of plastic are floating in the world’s oceans. From flip-flops to
microbeads, this pollution poses a serious risk for marine animals, which often
mistake plastic for food and starve to death or get caught in plastic packaging
and suffocate. Giant plastic islands like the Great Pacific Garbage Patch can
span for miles.
Since it’s too late to stop that trash from
entering the seas, the question is how do we clean it up? Here are some
creative ideas.
One such initiative comes from Reform
Studio, which has developed a rather ingenious solution to our plastic bag
epidemic, in which the bags become the feedstock for a traditional, yet
disappearing, industry in Egypt - handweaving.
Reform Studio is the brainchild of two
designers, Mariam Hazem and Hend Riad, who came up with the original concept as
their project for the Faculty of Applied Arts at the German University in Cairo
two years ago, in which they followed their belief that "design can solve
stubborn problems."
Arctic Sea Ice Shrinks
Lowest May average ice area ever recorded. Arctic heading
for lowest ever observed.
The average area of sea ice atop the Arctic
Ocean last month was just 12 million square kilometers (4.63 million square
miles), according to the National Snow and Ice Data Center (NSIDC). That beats
the prior May record (from 2004) by more than half a million square kilometers,
and is well over a million square kilometers, or 500,000 square miles, below
the average for the month.
This matters because 2016 could be marching
toward a new record for the lowest amount of ice ever observed on top of the
world at the height of melt season — September. The previous record September
low was set in 2012.
