Israel will celebrate Earth Day one day early this year, as the international UN-designated International Mother Earth Day lands on Saturday – April 22 — when everything is closed for the Sabbath.

The theme for 2017 is “Environmental & Climate Literacy.”

More than one billion people participate in Earth Day activities each year, making it the largest civic observance in the world.

“International Mother Earth Day provides an opportunity to raise public awareness around the world to the challenges regarding the well-being of the planet and all the life it supports,” reads a UN statement.

“Education is the foundation for progress. We need to build a global citizenry fluent in the concepts of climate change and aware of its unprecedented threat to our planet.”

The Earth Day Network created educational toolkits for schools, colleges and organizations to teach about climate change and environmental awareness.

In Israel, the Israel Nature and Parks Authority sent educational material to schools across the country with ideas of how to keep the earth a safe place for all.

Some schools will hold gardening workshops; others have asked children who usually come by car to school, to walk.
