New algae-based bioreactor can swallow carbon dioxide 400x faster than trees Digital Trends

For good reason, plenty of people are worried about the quantities of carbon dioxide (CO2) that are being pumped into the atmosphere. Since the early 1800s, scientists have known that greenhouse gases in the atmosphere trap heat, causing the effect we now know as global warming. CO2 is a particularly big contributor to this problem. Created as a result of the burning of fuels like oil and natural gas, CO2 makes up the overwhelming majority of greenhouse gas emissions. It represents around 72% of the total, compared to 18% methane and 9% nitrous oxide.
