Help the Rainforests of the World
 |
| Via The Pragmatic Progressive Page / Facebook |
How do we
define a rainforest? Although rainforests may vary, there are similarities that
we can identify:
·
Location: rainforests are found in the
tropics,
·
Rainfall: rainforests receive around 80
inches (200 cm) of rain per year,
·
Canopy: rainforests have a canopy, which is the
layer of branches and leaves formed by closely spaced rainforest trees. Most of
the plants and animals in the rainforest live in the canopy. The canopy may be
100 feet (30 m) above the ground.
·
Biodiversity: rainforests have a high level
of biological diversity or“biodiversity”. Biodiversity is the name for all
living things—like plants, animals, and fungi—found in an ecosystem. Scientists
believe that about half of the plants and animals found on Earth’s land surface
live in rainforests.
·
Symbiotic
relationships between species:
species in the rainforest often work together. In a symbiotic relationship, two
different species benefit by helping each other—you can think of it as a
partnership. For example, some plants produce small housing structures and
sugar for ants. In return the ants protect the plants from other insects that
want to feed on the plant’s leaves.
HOW CAN WE SAVE RAINFORESTS?
Rainforests
are disappearing very quickly. The good news is there are a lot of people who
want to save rainforests. The bad news is that saving rainforests is not going
to be easy. It will take the efforts of many people working together in order
to ensure that rainforests and their wildlife will survive for your children to
appreciate, enjoy, and benefit from.
Some steps for saving rainforests and, on a broader scale, ecosystems around the world can be abbreviated as TREES:
Some steps for saving rainforests and, on a broader scale, ecosystems around the world can be abbreviated as TREES:
·
Teach others about the importance of
the environment and how they can help save rainforests.
·
Restore damaged ecosystems by planting
trees on land where forests have been cut down.
·
Encourage people to live in a way that
doesn't hurt the environment
·
Establish parks to protect rainforests and
wildlife
·
Support companies that operate in ways
that minimize damage to the environment.

Plastic Paradise
Angela Sun talks about her journey to The Great Pacific Garbage Patch.
If you care about the future of the world's water, you've probably already watched films like Tapped, Blue Gold, Flow: For the Love of Water, and many others. Angela Sun's journey to The Great Pacific Garbage Patch will take you to an area in the Pacific Ocean contaminated by the plastic we use every day. She tells us that every piece of plastic every produced is still somewhere on the Earth. The devastation of plastic to our planet has been documented in many ways, yet we still buy bottled water and use plastic products at a staggering rate.
Plastic is going to last forever, but our clean drinking water won't.
Please, watch the video and read Angela Sun's report below.
Digging Into The Great Pacific Garbage Patch
By Angela Sun
Our earth is covered by more than 75 percent water, yet we know more about the moon than the depths of the sea. Today on World Oceans Day we celebrate and honor oceans by recognizing the underwater footprint we all unknowingly leave behind.
When it comes to plastic, what you throw away doesn't really go away. This was evident on my journey to one of the most remote ends of the earth - the Midway Atoll.
This small piece of land in the middle of the Pacific Ocean near the northwestern end of the Hawaiian archipelago was one of the most beautiful places I have ever been to, and should have been the most pristine. There are no cars, streets, lights or air pollution, yet I couldn't escape the remnants of modern society littered everywhere in the form of plastic.

At the dawn of the 20th century, scientists invented synthetic plastics as a replacement for raw materials. Plastic production grew more than 3,000 percent from 1927-1943. During the height of WWII, 85 percent of that production was devoted to war. This fantastic invention came in all shapes, sizes and materials such as nylon, cellophane, polyester, polystyrene, and methyl methacrylate, which are made to be durable and withstand the elements. There are great uses for plastics but it's the plastic products that are designed to be used once, but are made to last forever, that have become the main problem.
"The biggest landfill it turns out, is our oceans. We are just beginning to realize that," says Lisa Kaas Boyle, an environmental lawyer and co-founder of the Plastic Pollution Coalition.
"The request is always for a picture of this island of garbage, but there is no such island, the debris is dispersed. We have gotten samples from the Indian Ocean, [and] the Atlantic," says Captain Charles Moore of the Algalita Marine Research Organization who found the garbage patch in 1997 when he accidentally sailed through the area, "There's plastic in all of these oceans."
Because plastics are created from chemicals that are volatile in different environments, they will break down over long periods of time in the oceans through photo degradation, or exposure to the sun. The Scripps Institution of Oceanography at the University of California San Diego has found the proliferation of plastic pieces in our environment has infiltrated our oceans at an alarmingly rapid rate. Its latest study estimates the amount of particles of "microplastic"— pieces of plastic smaller than 5 mm in diameter — has increased more than 100 times since the early 1970s. Last year its team found nearly 10 percent of fish in the area had eaten plastic.
"These ecosystems are very connected. If the oceans are in trouble, we humans are in trouble. We don't realize that we are threatening our own existence," says Dr. Gregor Hodgson, founder and executive director of Reef Check Organization.
Ocean currents move around in a the world in a gyre, which is like a slow-motion whirlpool that opposes the wind and earth's rotational forces. Although the Pacific Ocean is the world's largest body of water, few people realize that there are in fact five subtropical gyres around the world - the North and South Pacific Oceans, North and South Atlantic Oceans, and the Indian Ocean. Dr. Marcus Eriksen, executive director of The 5 Gyres Institute, is currently leading an expedition sailing the course of the Japanese tsunami debris that is headed toward Canada and the U.S. "Having just crossed the western half of the North Pacific, we can report that the ocean is peppered with microplastics from California to Japan," he says.
An estimated 1.5 million tons of Japanese tsunami debris is headed west, and as recently as yesterday, a whole dock from the Japanese fishing town of Misawa arrived on the coast of Oregon. In April a soccer ball washed ashore in the Gulf of Alaska and was recently returned to its owner in Japan.
While filming the documentary, I found myself in serendipitous situations, especially when we encountered a hand-written letter from May 1999. It was written by a third grader in Long Beach, California.

At first I thought it would be great to return this to the young man, now probably around 23 years old, who wrote the letter. However, Lisa Dugan, his former teacher, had just thrown away her old records. I realized this message in a bottle found more than 5,000 miles from its origin more than 10 years later carries a much greater message for all of us. This moment was a stark reminder that consumers, producers and legislators should be accountable for what we put into the environment and where our trash ends up.
"The oceans provide our air, [they] provide a lot of our food and [they] regulate our climate," says Greg Stone, senior vice president and chief scientist for oceans with Conservation International. "If you put dollars and cents on those services, then we will be forced to from an economic argument to protect it. Right now we're not aware of those values, but the oceans are actually the most valuable asset we have on this planet—people don't get that."

The Majesty of Water!
 |
| Oceans cover about 70% of the Earth's surface and contain roughly 97% of the Earth's water supply. Water encompasses the matrix of all the possibilities of existence. It symbolizes the primordial substance that gives life to all forms and to which all return, through regression or cataclysm. Life within the ocean evolved 3 billion years prior to life on land...

Join ISSP August 23, 2012 at 11am PT as they host Maggie Winslow, PhD for an interactive webinar on her insight from ecological economics and what thermodynamic limits tell us about the economy.
The financial crisis that began in 2008, and the efforts to remedy the crisis, lay bare a troubling dichotomy. Our economy depends on increasing levels of consumption to maintain its health.However, the planet we live on is finite. Decreased consumption that has resulted from the crisis is a blessing for ecosystems and dwindling resources. However, it has also led to rising unemployment and all of the related negative social consequences.
Thus we find our economic system in a bind. We need to keep buying new goods to keep employment levels high and the economy strong. But buying all of these goods is not sustainable and is actually deleterious to the ecosystem upon which all life depends.
How did we end up in this situation? Part of the problem lies with the theory that underlies our market economy, neoclassical economics. This model, while elegant and useful in many ways, does not explicitly recognize ecosystem limits nor does it value lost natural capital and ecosystem services.
Maggie Winslow will present the basics of an alternative, transdisciplinary field called ecological economics. Ecological economics provides a view of the economy that takes into account the laws of thermodynamics, needs of future generations, and overall scale of the economy relative to the ecosystem. It also provides a framework from which business people can evaluate their firm’s performance and interconnections to the economy and ecosystem.
Dr. Maggie Winslow has been a professor of economics at Presidio Graduate School for the past nine years where she has taught Managerial Economics, Macroeconomics and Ecological Economics. Starting in the fall of 2012, she will be teaching in the Environmental Sciences Department at the University of San Francisco. Previously she taught at UC Berkeley, Antioch University, the Central European University, and for the Conservation Strategy Fund. She has also been a researcher for Redefining Progress, the Pacific Institute, the Environmental Defense Fund, the Conservation Law Foundation, and Lawrence Berkeley Lab where she worked on the economics of energy efficiency. She has a BA in Political Science from Williams College, a MS from the University of Michigan School of Natural Resources, and PhD from the Energy and Resources Group at UC Berkeley. Her dissertation work examined the relationship between economic growth, environmental quality and democracy. Her current research is on labor productivity, wages, and environmental quality.
