Guy:‘Why is the sky blue?
Actually, the sky was orange until about 2,5 billion years ago. The air was a toxic fog of carbon monoxide, carbon dioxide, nitrogen, cyanide and methane. The methane gave the sky an orange tint and the land a strange glow.Microbes called cyanobacteria formed in the ocean and they introduced something called photosynthesis, a natural process that converts sunlight and carbon dioxide into energy, creating oxygen as a by-product.
The cyanobacteria exploded across the ocean, pumping more and more oxygen into Earth’s atmosphere. Slowly, over the next two billion years, oxygen in the atmosphere rose to its present levels. When sunlight hits the oxygen molecules in our atmosphere, the blue light is scattered the most, giving the sky it’s blue colour.So thank you cyanobacteria for the oxygen and the blue sky, this place wouldn’t be the same without you!’
