Celebrated by over a billion people, Earth Day is one of the biggest holidays in the world.

Whether you're reducing your carbon footprint or just enjoying the great outdoors, there are lots of ways to celebrate. Not sure of what you want to do this Earth Day? Here are some of our favorites ideas.

Park Your Car for the Day

Take advantage of Tiger Transit and the War Eagle Bike Share for the day, or just enjoy walking around Auburn. Not only will it benefit the environment, but you will also save money on gas.

Get a Refillable Water Bottle

While this may not seem like the most exciting way to celebrate Earth Day, it does make a difference. Getting a refillable water bottle not only helps the environment by reducing plastic and oil waste, but it also helps your wallet. If you consumed the recommended amount of water each day in plastic bottles, you would spend about $1,400 annually. Refilling from the sink, however, costs only $0.49 per year. You can even refill your new water bottle for free anywhere on campus with Weagle Water stations.

Support Your Auburn Tigers

Celebrate our beautiful planet at one of Auburn’s outdoor athletic events! This Earth Day, Auburn’s baseball team will play against Arkansas at 1 p.m., and Auburn’s track and field team will be hosting and competing in the War Eagle Invitational all day.

Get a Reusable Grocery Bag

Those plastic bags at the store may be convenient to get your groceries home, but what happens to them when you’re done? They slowly break down for up to 1,000 years, causing the deaths of thousands of animals along the way. When they finally do degrade, they leave toxins behind. Find a cute, inexpensive tote online or a simple reusable bag from home to take to the store instead. The earth will thank you.

Support our Forests

Want to help the environment, but not sure where to start? Start with the trees. Stand for Trees works to protect the environment, combat climate change and promote the importance of forests through art, information and technology. You can donate to protect a specific forest community by purchasing a Stand for Trees Certificate here.

Go Outside

While the indoors can be a magical place, Earth Day gives the perfect opportunity to get outside. Have a picnic with friends, go hiking at Chewacla, rent an ENO from Auburn Outdoors or stroll through one of Auburn’s beautiful parks.
