Earth Hour: Turning Off the Lights to Take Action for the Planet...
Earth Hour is a reminder of the power that we have and an opportunity for us to come together as a community to make a difference. Whether it’s by turning off our lights, taking a walk in nature, or volunteering in our community, we can all do our part to make a more sustainable future. It’s not just about what we do in this one hour but the actions that we take every single day. Making small changes in our lives is what lead to changes, just like how one event in Australia turned into something we all know and join in on.

Earth Hour Evolves Into the Biggest Hour for Earth
Earth Hour is best known for the “lights off” hour, with people switching off their lights to show symbolic support for the planet and to raise awareness of the environmental issues affecting it. Eighteen years later, we need Earth Hour more than ever as Earth Hour organizers point out that humanity is “now at a tipping point with our climate and nature crises, putting at risk the fate of our one home and all our futures.”

Earth Hour: Turning Off the Lights to Take Action for the Planet...
Earth hour is set around the time of the Spring and Autumn equinoxes for both hemispheres of the planet. But what does this mean and why 8:30 pm local? Because this is when our two hemispheres have the closest sunset, allowing everyone across the globe to be a part of it near the same time. This also makes having the lights out hard to notice.

3 Things I Realized During Earth Hour
After getting over the initial emptiness of sitting in the dark, I started to realize that my mind was running freely. I didn’t have anything distracting me or pulling my attention. I ended up shuffling through my drawers to find a notebook and writing down the thoughts I was having. I journaled about my Earth Hour experience (hence this blog), wrote out my to-do list for the rest of the weekend, and even got started on a grocery list! Who knew an hour in the dark could be so productive?
