KALIKASAN-People's Network for the Environment is a network of people's organizations (POs), nongovernmental organizations (NGOs) and environmental advocates. It aims to address environmental issues but in such a way that primacy is given to the people—especially in the grassroots level—who constitute the overwhelming majority of the population. All environmental causes shall thus have the people's interest at their core. It was established to enable greater coordination and complementation in addressing the environmental issues which continue to worsen the lives of already marginalized people. So-called “development schemes,” in particular, have caused great environmental harm with correspondingly great human costs. "Kalikasan" is the Filipino term for nature.
