World Earth Day is held annually on April 22. Worldwide, various events are held to demonstrate support for environmental protection. This year’s theme is all about environmental and climate literacy.
Earth Day Network is launching a campaign for global environmental and climate literacy by Earth Day 2020. We are dedicated to ensuring that every student around the world graduates high school as an environmental and climate literate citizen, ready to take action and be a voice for change. This goal is not only an enormous undertaking, it is critical and timely. The signing of the Paris Agreement is one step towards mitigating the impacts of climate change. Education needs to be a key part of this effort.
