The environmental challenges of our time are urgent and interconnected. Biodiversity loss threatens the balance of our ecosystems, while climate change puts our food, water, and communities at risk. In a small, highly urbanized nation like Singapore, the stakes are high—but so is our potential to lead by example.

For a long time, it was still possible to say ‘more science is needed’ to understand how exactly human activities were harming the natural world.

One word sums up the incredible variety of animals and plants on Earth. It’s the magic ingredient that enables the world to work smoothly.

We’ve all seen photos of rainforests destroyed. Rivers littered with plastic. Headlines of wildfires and species going extinct. Biodiversity loss may not be happening at our doorstep, but it should hit close to home. Here’s why you should care, no matter where you are in the world.


Earth Hour is a powerful symbol, but real progress happens when awareness becomes sustained, coordinated action. Each of us has a role to play in our homes, workplaces, and communities, turning the commitment made during the hour into meaningful impact throughout the year.
Earth Hour Virtual Run 2026 celebrates 20 years of collective action for climate and nature. This year, go beyond switching off. Rally your friends, family, and community, and let’s move together with purpose.
By participating in the Earth Hour Virtual Run, you help support WWF-Singapore’s programmes and initiatives that protect wildlife, restore critical habitats, and strengthen climate resilience.
