Earth Day is an annual day on which events are held worldwide to increase awareness and appreciation of the Earth's natural environment. Earth Day is planned for April 22 in all years at least through 2015. The April 22 date was designated as International Mother Earth Day by a consensus resolution adopted by the United Nations in 2009. Earth Day is now coordinated globally by the Earth Day Network, and is celebrated in more than 175 countries every year.
