Whether you are already an ecology activist, or perhaps you're still struggling to sort recyclables, we all have a prime responsibility and opportunity during the week of April 22 to renew our individual and collective pledge to love the earth and tread more lightly on our planet.
More than half of the world’s population lives in cities. As the urban population grows and the effects of climate change worsen, our cities must evolve.
It’s time for us to invest in efficiency and renewable energy, rebuild our cities and towns, and begin to solve our climate crisis.
Over the next two years, with a focus on Earth Day 2014, the Green Cities campaign will mobilize a global movement to accelerate this transition.
