Earth Day has been observed since 1970 and is celebrated annually on April 22. It is a day dedicated to raising awareness about environmental issues and encouraging individuals to promote sustainability and protect the earth's natural resources. The theme of Earth Day 2023 is "Invest in Our Planet," which highlights the importance of dedicating our time, resources, and energy to address the environmental challenges we face -- at the local, state, national, and international levels. From climate change and pollution to deforestation and loss of biodiversity, our planet faces a range of pressing issues requiring immediate attention and action. Investing in Our Planet together supports a sustainable future, builds happy and healthy communities worldwide, and contributes to a healthy economy. 

Check out these events happening in Cumberland Valley to celebrate the importance of Earth Day.

A decade ago, the Pennsylvania Department of Conservation and Natural Resources (DCNR) launched a “Conservation Landscape” program that drives strategic investments around themes of conservation, community revitalization, and sustainability in special landscapes across Pennsylvania. Cumberland Valley is located in the South Mountain Landscape and features diverse natural, agricultural, recreational, and cultural resources. Within the South Mountain Landscape, community leaders, state agencies, local governments, philanthropies, and nonprofits all engage in ways to tackle effective conservation and community revitalization.
