Earth Day 2025
At Brookhaven Lab, we protect the environment by preventing incidents. We plan work carefully to prevent spills and other releases, reduce waste, and recover the valuable materials that result from our work for reuse. We preserve the beautiful campus on which the Lab is situated through planting for pollinators, vegetation management, and prescribed fire for ecosystem support and risk reduction from wildland fires.
Brookhaven Lab Earth Day Activities
Outdoor Yoga
4/22 and 4/24, noon - 12:45 p.m., Brookhaven Square Park
Enjoy nature while getting fit at the same time with a free Outdoor Yoga class hosted by the Brookhaven Employees' Recreation Association (BERA). While yoga is traditionally thought of as an indoor fitness program, performing yoga outdoors has many benefits. Practicing in open spaces makes your body work harder to adjust to wind and heat. It is thought to increase blood circulation, reduce anxiety, provide mental clarity, and relieve stress since energy is moving more freely and participants are closer to nature. We encourage you to join instructor Krista Shattess for this yoga flow class, open to all levels. Participants are encouraged to bring their own mats but there are some available to borrow should you need one.
The 45-minute class will take place in the center of the site at Brookhaven Square Park. In the event of inclement weather, the class will be relocated to the Recreation Hall (Bldg. 317). Please check the intranet calendar for updates. For more information, contact Kristyn Noren (Ext. 2400).
