Heard of the FAKE PLASTIC TREES?

Klaus Lackner, director of the Lenfest Center for Sustainable Energy at Columbia University, has come up with a technique that he thinks could solve the problem. Lackner has designed an artificial tree that passively soaks up carbon dioxide from the air using “leaves” that are 1,000 times more efficient than true leaves that use photosynthesis.

"We don't need to expose the leaves to sunlight for photosynthesis like a real tree does," Lackner explains. "So our leaves can be much more closely spaced and overlapped – even configured in a honeycomb formation to make them more efficient."

The leaves look like sheets of papery plastic and are coated in a resin that contains sodium carbonate, which pulls carbon dioxide out of the air and stores it as a bicarbonate (baking soda) on the leaf. To remove the carbon dioxide, the leaves are rinsed in water vapour and can dry naturally in the wind, soaking up more carbon dioxide.

Lackner calculates that his tree can remove one tonne of carbon dioxide a day. Ten million of these trees could remove 3.6 billion tonnes of carbon dioxide a year – equivalent to about 10% of our global annual carbon dioxide emissions. "Our total emissions could be removed with 100 million trees," he says, "whereas we would need 1,000 times that in real trees to have the same effect."

If the trees were mass produced they would each initially cost around $20,000 (then falling as production takes over), just below the price of the average family car in the United States, he says, pointing out that 70 million cars are produced each year. And each would fit on a truck to be positioned at sites around the world. "The great thing about the atmosphere is it's a good mixer, so carbon dioxide produced in an American city can be removed in Oman," he says.

GMO Myths and Truths


GMO Myths and Truths 
- An evidence-based examination of the claims made for the safety and efficacy of genetically modified crops.

by Michael Antoniou, Claire Robinson and John Fagan

Executive Summary:

Genetically modified (GM) crops are promoted on the basis of a range of far-reaching claims from the GM crop industry and its supporters. They say that GM crops:

  • Are an extension of natural breeding and do not pose different risks from naturally bred crops
  • Are safe to eat and can be more nutritious than naturally bred crops
  • Are strictly regulated for safety
  • Increase crop yields
  • Reduce pesticide use
  • Benefit farmers and make their lives easier
  • Bring economic benefits
  • Benefit the environment
  • Can help solve problems caused by climate change
  • Reduce energy use
  • Will help feed the world.

However, a large and growing body of scientific and other authoritative evidence shows that these claims are not true. On the contrary, evidence presented in this report indicates that GM crops:

  • Are laboratory-made, using technology that is totally different from natural breeding methods, and pose different risks from non-GM crops
  • Can be toxic, allergenic or less nutritious than their natural counterparts
  • Are not adequately regulated to ensure safety
  • Do not increase yield potential
  • Do not reduce pesticide use but increase it
  • Create serious problems for farmers, including herbicide-tolerant “superweeds”, compromised soil quality, and increased disease susceptibility in crops
  • Have mixed economic effects
  • Harm soil quality, disrupt ecosystems, and reduce biodiversity
  • Do not offer effective solutions to climate change
  • Are as energy-hungry as any other chemically-farmed crops
  • Cannot solve the problem of world hunger but distract from its real causes – poverty, lack of access to food and, increasingly, lack of access to land to grow it on.

Based on the evidence presented in this report, there is no need to take risks with GM crops when effective, readily available, and sustainable solutions to the problems that GM technology is claimed to address already exist. Conventional plant breeding, in some cases helped by safe modern technologies like gene mapping and marker assisted selection, continues to outperform GM in producing high-yield, drought-tolerant, and pest- and disease-resistant crops that can meet our present and future food needs.

230 million hectares of tree cover lost from 2000 to 2012

It is estimated that the world lost 2.3 million square kilometers (230 million hectares) of tree cover from 2000 to 2012—equivalent to 50 soccer fields of forest lost every minute of every day for 12 years 

The World Resources Institute (WRI), Google, UNEP and a group of more than 40 partners on 20 February 2014 launched Global Forest Watch (GFW), a dynamic online forest monitoring and alert system that empowers people everywhere to better manage forests. For the first time, Global Forest Watch unites the latest satellite technology, open data, and crowdsourcing to guarantee access to timely and reliable information about forests.

"Global Forest Watch is a near-real time monitoring platform that will fundamentally change the way people and businesses manage forests. According to data from the University of Maryland and Google, the world lost 2.3 million square kilometers (230 million hectares) of tree cover from 2000 to 2012 equivalent to 50 soccer fields of forest lost every minute of every day for 12 years. The countries with the highest tree cover loss are: Russia, Brazil, Canada, United States, and Indonesia.

"Managing the world's forest resources is today both a local and global undertaking, and technology has provided Global Forest Watch with an unprecedented opportunity to connect not only information and data but people, whether they be forest managers, businesses and private sector, or consumers across the globe. This is a great example of a community coming together and providing the world with a truly groundbreaking and pioneering product. Hopefully in a few years' time we will be able to monitor the impact and the results in terms of what actually happens on the ground that will be both a litmus test and I think the greatest affirmation that the time for this idea had come," said Achim Steiner, UN Under Secretary-General and UNEP Executive Director.

Global Forest Watch has the following features:

  • High-resolution: Annual tree cover loss and gain data for the entire globe at a resolution of 30 meters, available for analysis and download.
  • Near-real time: Monthly tree cover loss data for the humid tropics at a resolution of 500 meters.
  • Speed: Cloud computing, provided by Google, multiplying the speed at which data can be analyzed.
  • The crowd: GFW unites high resolution information from satellites with the power of crowdsourcing.
  • Free and easy to use: GFW is free to all and no technical expertise is needed.
  • Alerts: When forest loss alerts are detected, a network of partners and citizens around the world can mobilize to take action.
  • Analytical Tools: Layers showing boundaries of protected areas worldwide; logging, mining, palm oil and other concessions; daily forest fire alerts from NASA; agricultural commodities; and intact forest landscapes and biodiversity hotspots.

Global Forest Watch will have far-reaching implications across industries. Financial institutions can better evaluate if the companies they invest in adequately assess forest-related risks. Buyers of major commodities such as palm oil, soy, timber, and beef can better monitor compliance with laws, sustainability commitments, and standards. And suppliers can credibly demonstrate that their products are "deforestation free" and legally produced.

Global Forest Watch can support other users like indigenous communities, who can upload alerts and photos when encroachment occurs on their lands; and NGOs that can identify deforestation hotspots, mobilize action, and collect evidence to hold governments and companies accountable. Global Forest Watch can also help in designing smarter policies, enforce forest laws, detect illegal forest clearing, manage forests more sustainably, and achieve conservation and climate goals.

Global Forest Watch was created by the World Resources Institute with over 40 partners, including Google, Esri, University of Maryland, United Nations Environment Programme (UNEP), Imazon, Center for Global Development, Observatoire Satellital des ForĂȘts d'Afrique Centrale (OSFAC), Global Forest Watch Canada, ScanEx, Transparent World, the Jane Goodall Institute, and Vizzuality. Major companies have also provided early input, including Unilever and Nestle, and the wider Tropical Forest Alliance 2020 Partnership. Core funders include the Norwegian Climate and Forests Initiative, U.S. Agency for International Development (USAID), Global Environment Facility (GEF), U.K. Department for International Development (DFID), and the Tilia Fund.
