What countries do not celebrate earth day?

While Earth Day is celebrated in many countries around the world, there are some nations where it is not widely recognized or observed. Countries like Saudi Arabia, Afghanistan, and a few others may not have organized events or official recognition of Earth Day, largely due to cultural, political, or environmental priorities. However, individuals and small groups in these countries may still engage in environmental awareness activities independently. The level of awareness and celebration can vary significantly even within a country.
