  1. After outgrowing our old server we took our stuff and moved into a bigger, faster and better server. Unfortunately, the move took a bit longer than we initially thought it would take. This meant a prolonged downtime for our website and strange error messages for you. All in all, Green Blog was down for almost 48 hours during the server migration. 
    But the move is finally done.  B) You are now visiting Green Blog on our brand new VPS. :D What do you think? Isn’t it much, much faster?
    Let us know if you find any weird error messages or something that isn’t working as it should. Our community will use this default theme for a while until we upgrade and make our regular Green Blog-theme ready.
    Update 1: Due to the heavy traffic hitting Green Blog we exceeded our memory limit and the site went down for a couple of hours. The memory limit has now been increased and Green Blog is back online, again.
    Update 2: We're having problems with our mail. We are receiving your emails just fine, but we're having trouble replying to them.
    Update 3: Mail problems have been fixed.
    Update 4: Our old, Green Blog-styled theme is now working for everyone!

  2. Just like you said, there are various houseplants that can keep the air in our homes clean from pollutants and various harmful gases as well as balance indoor humidity.  I can't tell you which plant is the best, but here are several plants that you can use to clean the air in your household:
    First up is the Spider plant, also known as chlorophytum comosum (as seen in the picture above). This plant is great at removing poisonous gases in your home, but be prepared that it can grow very rapidly. If you have cats they will love this plant as it - just like ordinary grass - contains folic acid, a vitamin which is essential to a cat’s well-being.
    Another plant is the exotic-looking Boston fern (Nephrolepsis exaltata bostoniensis), which can also act as a natural humidifier.
    The Golden Pothos (Epipremnum aureum), also known as Devil’s ivy or silver vine, is sometimes considered as weed due to its rather invasive characteristics. But the plant is very efficient when it comes to removing indoor pollutants. Just note that the plant is toxic to both children and pets.
    A popular plant to remove indoor toxins is the Areca Palm (Chrysalidocarpus lutescens), best known for its humidifying effects. It's a rather sensitive plant that grows slowly and needs year-round care.
    The Aloe Vera (Aloe barbadensis) plant is one of my favourites. Thanks to its many medicinal properties it's a plant that is used in many skin care products, but it can also filter various gas emissions in your home.

  3. Seabirds and other animals often mistake plastics with food. These plastic objects slowly fills their stomachs over time until they are unable to ingest any real food. A slow death by starvation then follows for these poor seabirds.
    In Australia, this plastic rubbish is estimated to affect up to 65% of the seabird population. And Coca-Cola is currently trying to fight legislation that is key to fixing this problem. 
    This short ad, by Greenpeace, exposes how Coca-Cola is willing to let plastic pollution trash our oceans and kill our marine life. 
    Watch it: 
    Here's three things you can do to help stop Coca-Cola trashing Australia:

  4. Just a few days ago the European Union decided to ban neonicotinoid pesticides that allegedly causes serious harm to bees. In light of this decision, Mother Jones has a good article about the US and its reluctance to protect bees from harmful pesticides.
    In the US, "neonic-treated crops cover between 150 million to 200 million acres of farmland [...] each year—a land mass equivalent to as much as twice the size of the California."

  5. Bike-sharing programs are getting more and more popular around the world. This article takes a closer look on the history of bike-sharing and some of the cities in which this ecofriendly mode of transportation flourishes. 
    "Today more than 500 cities in 49 countries host advanced bike-sharing programs, with a combined fleet of over 500,000 bicycles."
    Urban transport advisor Peter Midgley notes that “bike sharing has experienced the fastest growth of any mode of transport in the history of the planet.” And the size and growth of these bike-sharing programs are amazing. One Chinese city's bike-sharing system could grow to 175,000 bikes by 2020.
    Also read about Copenhagen and Lund, two cities in Scandinavia where bicycles dominate the roads:

  6. You have nothing to worry about. These energy efficient light bulbs, or CFLs as they are also often called, are completely safe.


    The chemical you are referring to is mercury. Its true that mercury is a dangerous chemical, but the amount of mercury in a CFL is only 4 milligrams. This can be compared to the 500 milligrams that are inside every old-style thermometer that you put in either of your orifice. Here's another example to put things into perspective: a can of tuna, sadly, contains as much mercury as a CFL.


    That said, its important that you don't buy the cheapest brand and that you recycle your broken CFLs.


    Energy Star says this (pdf) about CFLs:


    "CFLs contain a very small amount of mercury sealed within the glass tubing – an average of 4 milligrams (mg). By comparison, older thermometers contain about 500 milligrams of mercury – an amount equal to the mercury in  125 CFLs. Mercury is an essential part of CFLs; it allows the bulb to be an efficient light source. No mercury is  released when the bulbs are intact (not broken) or in use.
    Most makers of light bulbs have reduced mercury in their fluorescent lighting products. Thanks to technology  advances and a commitment from members of the National Electrical Manufacturers Association, the average  mercury content in CFLs has dropped at least 20 percent or more in the past several years. Some manufacturers  have even made further reductions, dropping mercury content to 1 mg per light bulb."
    So in conclusion: CFLs are safe. Switching from traditional light bulbs to CFLs (or LEDs) is an effective way to save money and electricity.

  7. Do you consider the hidden environmental footprint when your buy and drink Coca-Cola, or any other similar carbonated soft drinks? Yeah, probably not! ^_^


    The infographic below shows some of these hidden environmental costs and health issues that comes with drinking carbonated soft drinks. For example: While drinkable and clean fresh water is a precious natural resource it takes three bottles of water to produce one bottle of Coca-Cola.


    It's important that we take responsibility for the things we choose to consume.

  8. The internet vigilantism and bad journalism in the wake of the Boston Marathon tradgedy is sickening! A high school student now fears for his life after being wrongfully labelled as a suspect for the Boston bombing by the New York Post and users on both Reddit and 4chan.


    "A teenager says he is scared to go outside after he was portrayed on the internet and on the front page of the New York Post as connected to the deadly Boston Marathon bombings. Photos of Salah Eddin Barhoum, 17, and friend Yassine Zaime were posted on websites whose users have been scouring marathon-finish-line photos for suspects."

  9. Hugo+Chavez1.jpg


    President Hugo Chavez has lost his two year long battle against cancer. But "those who die for life, can’t be called dead," Vice-president Nicolas Maduro said tonight when he made the announcement on public television.


    This is heartbreaking news! Hopefully, the Bolivarian revolution won't lose momentum so that it can continue to improve people's lives and strengthen democracy in Venezuela.

  10. Does anyone here have any opinion on the Rodale Institute?


    Are they professional in their work or can they be considered too biased? Their ongoing Farming Systems Trial (FST) where they compare organic farming systems to more conventional ones seems interesting. But I've heard some worrying stories about their support for "compost" making from toxic sewage sludge.

  11. This response by Ian Angus to David Attenborough's overpopulation comment is essential reading.


    In an interview last week, Attenborough called humans "a plague on the Earth" and called on the world to put limits on population growth.


    "Yes, there is a plague on the earth, but it isn’t people," Angus writes in his response to Attenborough. "It’s a social and economic system that puts profit before people, that treats food as a commodity instead of as a basic human right. So long as that system remains in place, hunger and poverty will continue, no matter what happens to birth rates."

    What do you think? Do you agree with Angus or Attenborough?

  12. It's that time of the year again when Japanese whalers sets sail for the Southern Ocean Whale Sanctuary in Antarctica to begin their unnecessary and cruel slaughter of whales.

    "There is no difference between what the Japanese are doing in the Southern Ocean whale sanctuary and what elephant poachers are doing in the eastern Kenya. Except that in Kenya poachers are black, they are poor and they get shot for what they are doing."

    Read the whole article:


    This video is spot on! Exxon and other energy companies are killing our climate and destroying the lives of future generations. And the worst thing is that they are fueling climate disaster on taxpayers’ dime. The US alone gives at least $10 billion annually to Big Oil, Gas and Coal.

    And Sweden isn't much better. We are the biggest subsidisers of fossil fuels among all Annex II countries. All in all, governments around the world spend $1.4 billion every day to fuel climate chaos.

    It's time to stop pretending that energy companies like Exxon or Vattenfall are anything but climate killers who hates your children.

  14. I missed this discussion during the recent reporting of the World Bank climate report. But thankfully we have Al Jazeera English...

    Is the World Bank turning up the heat?

    Bank warns dire consequences if global warming is not countered, but its own work may be contributing to climate change.


    Watch it:

  15. In his victory speech last night, Obama finally mentioned climate change:

    “We want our children to live in an America that isn’t burdened by debt, that isn’t weakened up by inequality, that isn’t threatened by the destructive power of a warming planet.”

    Shortly after Obama’s victory was announced Bill McKibben, from, tweeted:

    “Obama has been re-elected president in the warmest year in American history. We’ll see now what he thinks his legacy should be. Obama never has to run again. Now we’ll find out what he really thinks about a lot of things.”

    Do you think Obama’s victory will mean four more years of business as usual, or will we finally start to see real change and real progress on climate change?

  16. So far both Barack Obama and Mitt Romney have been silent on climate change during the presidential debates. During the previous debate, while Mitt Romney was busy attacking the President for not doing enough for the fossil fuel industry, Obama proudly talked about how oil and gas production was at all-time highs and that he would "continue to open up new areas for drilling" and make natural gas "a priority".

    Climate change has come up in one form or another during every election debate from 1988 to 2008. If it doesn't come up tonight, at the last presidential debate for this election, it will be the first time a climate issue isn't raised since 1984.

    It is absolutely imperative that climate change is brought up in tonight’s discussion. But even more important is that we also get good responses from Romney and Obama.

    Check out Climate Silence and demand that the candidates tell Americans how they plan to address the climate crisis if elected.

  17. I recently read Wired's September issue and their "Apocalypse Not" cover story by Matt Ridley. It's a stupid article where Ridley in an ignorant and old-fashioned liberal way downplays the dangers of climate change. His whole argument against the dangers of global warming basically goes like this: “we have successfully combated malaria with pesticides and money – therefore the other effects of climate change are equally overblown and they will most likely be as easy to solve.”

    I was about to write a longer post about it, but meh, it's not worth my time. So I’m glad I found this blog post from Grist which successfully trash this piece of garbage journalism.

  18. Hello and welcome to the forums!

    Yes, knowledge is the first step towards meaningful change. :)

    "Its inspiring to witness the Green Revolution that is taking place at a descent pace worldwide."

    I would say that the green revolution is too slow and that its taking too many breaks. ;)

    Hope to see you around in the fourms!
