Earth Day 2014: Green Cities
Earth Day 2014 will focus on green cities, mobilizing a millions of people to create a sustainable, healthy environment by greening communities worldwide. Today, 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 have to evolve.
It’s time for us to invest in efficiency and renewable energy, rebuild our cities and towns, and begin to solve the 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. Join us in calling for a new era of green cities.
Mother Earth is a common expression for the planet Earth in a number of countries and regions, which reflects the interdependence that exists among human beings, other living species and the planet. For instance, Bolivians call Mother Earth Pachamama and Nicaraguans refer to her as Tonantzin.
Recognizing that Mother Earth reflects the interdependence that exists among human beings, other living species and the planet we all inhabit, the General Assembly declared 22 April as International Mother Earth Day (A/RES/63/278).

Get involved with Earth Day!
Every year on April 22, over a billion people in 190 countries take action for Earth Day. From San Francisco to San Juan, Beijing to Brussels, Moscow to Marrakesh, people plant trees, clean up their communities, contact their elected officials, and more—all on behalf of the environment.
Like Earth Days of the past, Earth Day 2014 will focus on the unique environmental challenges of our time. As the world’s population migrates to cities, and as the bleak reality of climate change becomes increasingly clear, the need to create sustainable communities is more important than ever. Earth Day 2014 will seek to do just that through its global theme: Green Cities. With smart investments in sustainable technology, forward-thinking public policy, and an educated and active public, we can transform our cities and forge a sustainable future. Nothing is more powerful than the collective action of a billion people.
