Earth Day is celebrated around the world every April 22, bringing together the different sectors of the society for a common purpose, and strenghtening their environmental advocacies. In Philippines, Earth Day celebrations have a uniform theme "Earth Day Everyday, Everywhere, for Everyone".
Alarmed by the extent of environmental degradation in the USA in 1970, Wisconsin Senator Gaylord Nelson, saw the need to bring the environment into the national agenda. Twenty million Americans took to the streets, parks and auditoriums to demonstrate for a healthy and sustainable world. Thus begun the Annual Earth Day celebrations.
In 1990, the celebration became global. More than 100 countries participated. Countries were free to pursue whatever priority environmental issue they wanted to focus on and how they would celebrate April 22 as Earth Day.
In 1999, to prepare for the 30 years anniversary of the celebration, the international secretariat called on its global partners to formally organize local Earth Day Networks to show that various sectors of society were working together to achieve one common goal.
Since April 22, 2000, Earth Day celebrations have become more focused and more coordinated. While different groups are still encouraged to carry on with their respective advocacies, their efforts are made known to others so that synergies are developed for greater impact. Thousands of Earth Day activities take place worldwide, and more than a billion people around the globe celebrate Earth Day each year.
With the issuance of Proclamation No. 1481, Earth Day on April 22 is now a permanent environmental celebration in Philippines. Earth Day Network Philippines Secretariat serves as the coordinating body for all Earth Day celebrations and events in the country, bringing together government, civil society, businesses, churches, and academic institutions to appeal to the Filipino people that Environmental Security is the highest form of National Security.
