You probably didn’t hear about it, but in 2008 Estonia cleaned up 10,000 tons of trash in their forests by recruiting 50,000 people. How? Through an extensive media campaign and a good dose of networked collaboration.
The “Let’s Do It!” website is here, but in Estonian. So here’s a video in English!
Based on the success in Estonia, the campaign has gone worldwide!
Apparently copper can be used to scrub pollutants out of the air. Maybe one day a penny can help clean your house.
An easy way to get carbon dioxide out of the atmosphere is to find a chemical that combines easily with it, similar to the way that some metals oxidize. For example, compounds involving copper will usually combine with oxygen in the atmosphere voluntarily without catalysts, covering the surface of the copper material with a green patina, like the Statue of Liberty.
Unlike oxygen, carbon dioxide cannot combine so easily with other materials. It is possible to remove one electron from the molecule to facilitate its integration into other molecules, but that removal requires an electric potential of -1.97 volts, which is unreasonably high for the purpose of processing a single molecule.
One group of scientists found a certain dinuclear copper (I) complex that turns green when exposed to air under a slight electric potential (-0.03 volts). At first, they assumed it was from the exposure to oxygen, but upon closer inspection they learned that this particular form of copper was reacting with carbon dioxide.
You read that right: wind power generation can shelter sea life. Offshore wind farms help create spaces that encourage sea life to grow in a similar fashion to coral reefs.
Offshore wind power and wave energy foundations can increase local abundances of fish and crabs. The reef-like constructions also favour for example blue mussels and barnacles. What’s more, it is possible to increase or decrease the abundance of various species by altering the structural design of foundation. This was shown by Dan Wilhelmsson of the Department of Zoology, Stockholm University, in a recently published dissertation.
“Hard surfaces are often hard currency in the ocean, and these foundations can function as artificial reefs. Rock boulders are often placed around the structures to prevent erosion (scouring) around these, and this strengthens the reef function,” says Dan Wilhelmsson.
Some research that was released late last year found that people in the UK really like caring for the environment with recycling being the most popular green practice.
Green behaviours costing the least money and effort are currently the most popular with the British public, despite the fact that 59 per cent of people think that if things continue on their current course we will soon experience a major environmental disaster.
A fuller picture of environmental and other behaviours and attitudes based on the first annual survey of 100,000 individuals from 40,000 households for Understanding Society will be published at a later date.
Depressed about the Copenhagen Accord? While the action on climate change may have been less than you were hoping for, Worldchanging.com has an article explaining how the conference signaled a different kind of sea change. According to Alan Akisson, this was the first major event where developing nations had voices as loud as the developed, in a truly democratic process.
The Earthquake in Copenhagen truly marked the end of one historical era, and the beginning of a new one. It is an era of more democratic global governance (at least in the sense of how power, actual and perceived, is dispersed among nations). An era of continuous struggle to understand what is happening to our planet, and continuous effort to share that understanding. An era of nations being forced to collaborate, more and more closely, and over several decades, on planetary management. In the hindsight of future history (especially environmental history), CoP-15 will likely loom large indeed as an inflection point, a time when everything changed — or rather, was finally seen by all as changed.
