Happy Earth Day

It's hard (at least for me) to think about Earth Day without at least thinking about some of the issues we have created for our little blue planet.

So I offer, this presentation which summarizes the proposal published in Science back in 2006 by Pacala and Socolow based on their studies at Princeton University. While I do not agree with every recommendation suggested (I am strongly opposed to corn and soy-based ethanol) I do think it does a decent job of quantifying attainable solutions to curbing carbon emissions in the immediate future.

For those naysayers (Hi, Dad!) who do not think the retooling of a green America is feasible, I offer this point. At the start of the US involvement of World War II, the following wartime production goals were issued on January 6, 1942:
  • 45,000 tanks
  • 60,000 planes – (229,000 produced by 1945)
  • 20,000 anti-aircraft guns
  • 6 million tons of merchant shipping
  • Production of Automobiles was banned for 3 Years
It took only five months to restructure the economy.
Recycling, particularly of metals, on a large scale was enforced.
Victory gardens and rationing encouraged less waste and locally grown produce.

If we could do that based on the technology of the 1940s, surely we are even more capable of greater innovations today.

At this point in the post I was going to address the concerns of those who feel that the climate crisis is exaggerated, unreasonable or otherwise imaginary...(Hi, again, Dad!) but I don't think that focusing on the gloom and doom is the best way to move forward, so instead, I offer some resources for those who are interested in resizing their carbon footprint.

EIA provides this information to promote sound policy making, efficient energy markets, and public understanding about energy and its interaction with the economy and the environment. By law, EIA’s products are prepared independently of Administration policy considerations. EIA neither formulates nor advocates any policy conclusions. This isan excellent resource to look at national energy data and economic or event-driven issues that may impact theenergy market.


Happy Earth Day, Everyone!

Think the Whales are Saved? Think Again.

Save the whales? Didn't we do this already? This is a question I've heard quite a bit lately. The truth is that although some whale species have increased in numbers due to the conservation efforts of the 70s and 80s, most species are still threatened and many are at the brink of extinction. The issue is current. One of the final acts of the Bush administration was to kick-off the process of effectively ending the international moratorium on commercial whaling by pulling together a "small working group" and drafting text that extends "scientific whaling rights" into international waters. I recently had the pleasure of attending a presentation by Jake Levenson of the International Fund for Animal Welfare that helped summarize the current and continued threats to whales worldwide.

Many people believe that the major threat to whale species was solved with the 1986 worldwide commercial whaling ban. However, an estimated 30,000 whales have been killed in the last two decades since the ban. Japan has increased its “scientific whaling” practices which are allowed under the treaty. Iceland also continues its whaling practices using this loophole. Whaling ships in Iceland often follow whale watching vessels to find easy targets. These hunting practices often involve the use of grenade tipped or explosive harpoons, which promise to provide an 'instantaneous' death but often take several hours to kill the animal. Multiple gunshots are often used to 'speed up' the process. Although this whaling is done in the name of scientific research, all of the scientific information that is gathered can now be obtained through humane practices. Additionally, meat and oil products from endangered whale species (by products from scientific whaling) can be found in markets in several countries.

Aside from the direct threats of commercial whaling efforts, whales face three major anthropogenic threats: sound pollution, vessel collisions and entanglement. Sound travels twenty-five times faster underwater than it does through air. For most marine life, sound is not only something that is heard, but also something that is felt. Whales have evolved to communicate across oceans, in order to find hunting grounds or potential mates. Ocean background noise levels have doubled every decade for the last 60 years, causing confusion, navigation issues and potentially inhibiting mating. The primary causes of increased ocean noise include oil exploration, oil related construction and drilling, military sonar and increased shipping activity. Mass strandings of whales can be linked to military sonar activity nearby.

Vessel collisions can result in immediate death or severe injury to the whales. Amputation of fins or gashes that do not result in death can leave the animals open to infection and impair swimming abilities. Four out of six of the right whale deaths recorded in 2006 are attributed to collisions with ships. The reason is simple. Shipping has increased dramatically in the past decade and shipping lanes directly overlap right whale habitat.

More than 300,000 cetaceans die annually due to entanglement. IFAW believes this number is an extremely conservative estimate because it is reported by fishermen and not every country provides reports. The organization believes that the number is closer to 900,000. Entanglement is the number one cause of extinction among whale species. It is a slow, painful death generally realized through starvation or exhaustion. When entanglement does not result in the death of a whale it can compromise their physical conditions, leaving the individual prone to infection or adversely impacting its behavior. Again, understanding the problem is simple. There is too much rope in the water. Whale + Rope = Panic. Distentanglement efforts can be logistically difficult, dangerous to both whales and humans and can cause additional trauma to the whale. Whales must be tracked and essentially trapped in order to cut away the lines attached to their bodies.

IFAW has implemented some innovative and technologically interesting solutions to many of these anthropogenic threats. For example along the eastern coast of the United States they have deployed 13 buoys along major shipping routs. The buoys are equipped with hydrophones that listen for whale calls and alert the shore and nearby ships of whale activity nearby. The system works much like the ones used by airplanes and radio-control towers to avoid collisions in the air. There are also efforts underway to develop remote controlled rope cutting devices to provide a less traumatic disentanglement process.

Here's what you can do to Save the Whales (again)...

Send a letter to your congressperson(s) through Stop Whaling Now: http://www.stopwhaling.org/c.foJNIZOyEnH/b.4489567/siteapps/advocacy/ActionItem.aspx?msource=DR080902001

SHOW US YOUR TAIL! 

IFAW is collecting worldwide pictures of people showing their support for the whales. 
As enough pictures for a country are collected, they are published in book form and sent to the government leaders of those countries.
