In 1800 there were about 1 billion people on the planet.
It then took around 127 years before the population reached 2 billion.
Can you guess roughly how long it took for humanity to add the last billion?
a.) 127 years b.) 60 years c.) 30 years d.) 12.7 years
If you answered d then you are correct and with over 7.2 billion of us the population is still growing. However what’s more worrying than rapid population growth in a heavily overburdened biosphere where human induced extinctions already occur on a daily basis is the rapid increase in unsustainable consumption which unlike population growth shows no signs of slowing down anytime soon. Reduce, Reuse, Repair, Reuse, Recycle
P.S. Can you name the top five countries according to population size? For the answers check out the bottom of this map that shows country size adjusted according to population size.
