The Philippines is one of the most beautiful and environmentally diverse countries in the world, with countless plants and animals inhabiting its many islands. But the country is also sadly marred by violence, as the Philippines has consistently ranked as one of the most dangerous places to be in for environmentalists, with studies showing that the country is the deadliest place in Asia for people defending their land and the environment. Still, in the face of the constant harassment, persecution, and even deaths, the push to protect the country’s biodiversity as well as climate action and justice persists.

Among those helping lead the charge are brave, passionate, and headstrong women who, despite the dangers, remain steadfast in their principles. While addressing pressing issues like the climate crisis requires a collective effort, these Filipinas are fighting the good fight in protecting the land and ecosystems, protesting against climate change and injustice, educating the next generation on the importance of the environment, and championing sustainable practices geared towards people and the planet over the abuse of natural resources.

Below, get to know some of the Filipina environmentalists who are using their platforms for the betterment of the Philippines and the world.
