People, Spaces, Deliberation bloggers present exceptional campaign art from all over the world. These examples are meant to inspire.

Earth Day, celebrated annually on April 22, seeks to raise awareness and support for environmental protection.

2015 is the 45th anniversary of Earth Day and the theme this year is "It's our turn to lead," raising hopes that people can lead by example in protecting the environment so that world leaders might follow.  The Earth Day Network is hoping that 2015 will be the year "in which economic growth and sustainability join hands."  

Greenpeace, a non-governmental environmental organization working to "ensure the ability of the Earth to nurture life in all its diversity", campaigns on global issues like climate change, deforestation, the health of the oceans, and ecological farming. The following video, like this year's call to action, encourages us all to lend a helping hand.

The Dog Days of Summer

During these last warm days of summer, how about some climate cooling? This unusual idea is being proposed by David Keith, professor of public policy and applied physics at Harvard. In an article in the MIT Technology Review, Keith says that reducing carbon emissions alone won’t be enough to stave off the arctic ice melt or loss of crops due to higher temperatures. He says that “geo-engineering” is one way to do this. This idea’s not without risks, however, and of course it is still untested.

The issue of climate change though is quite serious, and according to Turn Down the Heat: Why a 4°C World Must Be Avoided, a report by the Potsdam Institute commissioned by the World Bank, the scenario of a world warming to 4°C is likely in this century. It should be noted that a warming of 2°C is considered by many to be the “tipping point” for irreversible environmental damage.
