Earth Day 2021

April 22, 2021, is the 51st celebration of Earth Day. Celebrate with us across Pitt and in Pittsburgh with virtual events and education

The first Earth Day on April 22, 1970, was a national “teach-in” event focused on educating people about the environment. Across the U.S., 20 million Americans (10% of the population) took to the streets, to protest pollution of their natural places.  As a result, in December 1970, Congress authorized the creation of a federal agency specialized in tackling environmental issues: the U.S. Environmental Protection Agency (EPA).

Earth Day has been annually celebrated in the U.S. for 51 years, and the University of Pittsburgh has been an active participant advancing sustainability initiatives since 1970. Learn more here. 

To honor Earth Day this year, here are some ideas on how to celebrate at home and virtually!

Learn How to Be More Sustainable! 

Learn about Recycling and Reduce Waste

Do you know that the slogan”Reduce, reuse, recycle” is organized by priority? Earth Day is the perfect time to think of ways you can reduce your waste and look for opportunities to reuse items. 

Before throwing an item away, spend some time learning about the recycling options near you. Recycling is an environmentally friendly activity which helps to reduce waste from the landfill and can help promote the circular economy.

Make sure you know what items can be recycled in your county. “Wish-cycling” is a term coined by the industry that refers to all the things residents throw into recycling that end up contaminating the collection stream.

Take a Walk or Bike Ride

Earth Day is a great chance to get out and spend some time in nature. If you are in Pittsburgh, there are great places in Pitt’s backyard to get outside and see the sprouting trees. Take a walk through Schenley Park, Frick Park, or anywhere else near you. 

Alternatively, take a bike ride! This could be as transportation for the day or for a fun leisurely ride. Check out Pitt Mobility tips when planning your bike outing.

Don’t have a bike? Pitt employees and students can use The Healthy Ride bikes in Pittsburgh for free 30-minute rides!

Make Some Personal Sustainability Goals

Take some time during this day to make up a few personal sustainability goals: short-term, long-term, or both!

  • Plant something! Increase the air quality in your home with an indoor plant or grow some fresh veggies in your backyard or plant a tree.
  • Use reusable shopping bags: Did you know that plastic bags are used on average for only 10 minutes before they are thrown away? Help end the single use plastic problem by switching to reusable bags.
  • Practice the three Rs: The three Rs are Reduce, Reuse, and Recycle and they are super important-in that order!
  • Unplug appliances when not in use.
  • Use reusable cups and water bottles: This action can keep countless plastic bottles and coffee cups out of the landfill where they will sit for thousands of years.
