April 23, 2026, NIH will celebrate Earth Day with the theme of "Our Power, Our Planet".  Earth Day helps provide us an opportunity to recognize the importance of protecting the environment and understand its impact on human health.  We encourage you to join us in taking part and learning about NIH programs and from outside vendors in protecting the environment, reducing energy consumption, minimizing waste generation, and containing operational costs so that we conserve our resources for the NIH mission and be good stewards of planet earth.  Please see the some of the following opportunities you may enjoy in this year's celebration:

-The NIH Stream walk that highlights the environmental features along the stream that helps promote its    health and strengthen the aquatic life surrounding it.  

-The distribution of at least 300-400 tree saplings​ for you to take and plant at home or surrounding areas

-Local farmers market for you to enjoy some local treats, flowers and more

-Maryland's very own Bonsai Club where you can learn and practice the craft of creating a Bonsai.  Bring your   own if you have one at home!

-Come see live animals on display.  You never know what might show up this year!  

-Maryland Master Gardners

-Montgomery County Beekeepers​

 Much more to come and see!​​
