The Risk and Reward of Sunlight

if this happens, make sure that you don t shave off that decimal and travel back to 2 billion years ago. At that point, oxygen concentrations hit a wall and 

The sequence may have started with carbon chains acting as umbrellas. To see these colors in action, start at Lake Hiller, which sits southeast from the Shark Bay stromatolites in Australia. The lake is surrounded by green forest and sits near the blue ocean, which only serve to highlight the water s bright pink color. Not slightly pink or squint at sunset and it looks pink, but Bazooka-bubble-gum princess-birthday-party pink. 

This pink or red color can be found in other lakes across the world. You may have seen some in San Francisco Bay as you approach the airport, which are artificial ponds for making sea salt. The Dead Sea and Mono Lake are other salty reservoirs where salt-loving microbes bloom. The pink and red colors come from long carbon chains called bacterioruberin. The microbes weave this red pigment into their cell membranes, like the tiny red threads in a paper dollar. 

On the other side of the world is a bright magenta river made by different carbon-chain pigments. Located in Columbia, this river is officially Cano Cristales and unofficially The River of Five Colors. Since it was discovered by the Internet, it has graced countless computer monitors with pictures of green, pink, orange, yellow, and red mosses and plants growing under crystal-clear waters. 

This intense color may be caused by the same pigment molecule that makes my Japanese maple turn the same bright red in the autumn, and turns other leaves deep
