Earth Day is an annual event celebrated around the world on April 22 to demonstrate support for environmental protection. "The urgent challenge to protect our common home includes a concern to bring the whole human family together to seek a sustainable and integral development…Humanity still has the ability to work together in building our common home. Young people demand change. They wonder how anyone can claim to be building a better future without thinking of the environmental crisis and the sufferings of the excluded. (Laudato Si’ 13)
