It’s essential that we “Invest in Our Planet ,” the theme for this year’s Earth Day. The day highlights the urgency of dedicating our time, resources and energy to solving climate change and other environmental issues as soon as possible. Educators and students can mark the day — the year! — through education, awareness and action — such as planting trees, participating in cleanups, ending plastic consumption, practicing climate literacy and championing sustainable fashion.
