International Day of Caves and the Subterranean World.

On June 6th, the world celebrates the International Day of Caves and the Subterranean World. This day is observed by the International Show Caves Association (ISCA) and is marked by show caves, mines, and organizations worldwide. It's a time to raise awareness about the importance of caves and underground environments for environmental conservation, education, and the preservation of these unique ecosystems. ISCA organizers often feature events like special tours, educational activities, and lectures by experts in speleology.

World Green Roof Day

 

World Green Roof Day is celebrated on June 6 every year to appreciate the beautiful green roofs that contribute to a better environment and raise awareness about their importance to climate change. Did you know the first record of green roofing was the Hanging Gardens of Babylon, planted in Iraq in 500 B.C.? Also known as living roofs, they consist of vegetation that partially or completely covers a waterproofing system. Green roofing lowers the cost of cooling and reduces stormwater runoff. World Green Roof Day is an initiative by Chris Bridgman and Dusty Gedge, experts in sustainable green roofs.

National Eyewear Day (United States)

 

June 6 is National Eyewear Day, an awareness day founded in 2016 to encourage people to schedule their next eye exam. The eye care community, including eye doctors and opticians, observes the day by educating the public about eye health and why it’s important to get regular eye exams.

Why National Eyewear Day is important

National Eyewear Day is a reminder that taking care of your eyes should be part of your annual health care routine. Having a comprehensive eye exam every year is the best way to make sure that:

·    Your eyes are healthy.

·    Your vision is clear (with or without correction).

·   Any changes in your eye health or vision are monitored and acted on appropriately.
