September 21, 1972, marked the beginning of a dark chapter in Philippine history. When Ferdinand Marcos Sr. placed the country under Martial Law, extraordinary government powers were used to suppress dissent and strengthen state control. The consequences extended beyond political repression, reaching forests, rivers, mountains, and ancestral lands whose communities were often displaced in the name of development.

Fifty-four years after Martial Law, displacement, environmental destruction, and the persecution of community advocates remain pressing concerns.

Today, we remember the horrors of Martial Law not only to remember the abuses committed against the Filipino people under the Marcos dictatorship, but also to honor the courage of those who stood up and fought for change.

As environmental advocates, we must not allow history to repeat itself. Let us continue to stand against the destruction of our forests, rivers, and communities, and defend the people whose lives and livelihoods are threatened in the name of development.

Our struggle for environmental protection is also a struggle for human rights, justice, and a future where communities and nature are valued over profit and power.

We are beyond grateful for everyone who joined and contributed to our E-Waste Collection! ๐Ÿ’š

Your efforts helped keep old and unused electronic devices and waste from improper disposal and brought us one step closer to a cleaner, safer, and more sustainable community. Through this, we showed that responsible e-waste management is a shared responsibility. ๐Ÿค โ™ป๏ธ

Thank you for helping us turn environmental action into collective action. Together, we continue working toward a more circular and sustainable campus. ๐Ÿ’š

Since its re-establishment in 2009, intellectual environmentalism has been the central philosophy of UP ECOSYSTEMSS. We hold deep importance to the intellect of different experts, from local communities to engineers and scientists, to solve the various environmental problems that we are facing.

Today, we are reminded of our core with the International Youth Day. We may have different contexts in reality but we are united by our common aspirationโ€”which is to protect and conserve the planet for future generations.
