Happy Earth Day from COSI! As the new Manager of Energy and Environmental Initiatives I'm excited to take this opportunity to highlight some of the great work COSI has committed to in the name of sustainability.

One way that COSI has gone green, is through composting. If you have been to COSI in the last year, you may have noticed that we collect food scraps in our Atomic Café. But, our composting efforts don't stop there! Many of our service items (such as napkins and condiment cups) are compostable too. COSI's commitment to compost doesn't end with our visitors. Our food service staff practices what we preach in the kitchen by separating out food waste from other waste items. These efforts lead to the collection of 18.14 tons of compostable material in 2012!

1) The Earth isn't round!

Actually, (like a lot of us) the Earth is a bit plump about the middle. Why? Because it's spinning so fast! The Earth's rotation creates stress on the rocks and the oceans, causing the planet to bulge around the equator. In fact, because the Southern Hemisphere is mostly ocean and because water is easier to move than land, the Earth is a little bit pear-shaped!

2) The tallest mountain is . . . well . . .

You probably said Mount Everest right away. It's true that Everest is the point on Earth farthest from sea level. However, there are at least two challengers to Everest's claim. If you measure base to peak, then Mauna Kea in the Hawaiian Islands is actually about four thousand feet taller than Everest. Of course, Mauna Kea begins on the bottom of the Pacific Ocean and doesn't even break sea level until it's already almost 20,000 feet high. But if you put the two side by side, Mauna Kea would actually be larger.
