In this way, the UN wants to establish a direct connection between the fight against climate change and human happiness and well-being, according to an official statement.
"The Angry Birds have entertained millions of people around the world — and now they are part of making the world a better place," UN Secretary-General Ban Ki-moon said.
The organizers of the campaign — Sony Pictures, the United Nations Development Programme (UNDP) and the UN Foundation — hope that the campaign will go global and urge people to improve their attitude towards the environment.

To participate in the campaign, social network users should publish their comments and pictures with the hashtag #AngryBirdsHappyPlanet, testifying their commitment to environmental conservation. For instance, they could share their ideas about how to preserve the environment or demonstrate what steps they take to make the world better.
"Nothing pleases the evil birds as a healthy planet," Angry Birds' producer John Cohen.
Since 2013, the UN has annually viewed the Day on March 20 as a way to recognize the relevance of happiness in the lives of people worldwide. This year, the UN decided to emphasize the connection between having a healthy planet and happiness.
