There was news today that the population of the Planet had reached 7 billion – 7,000,000,000 folks crawling, walking and ambling around. I mentioned before that to visualise this you need to fill a Post Box with sand – the individual grains add up to approximately 7bn. Alternatively put all the people side by side – and they would fill the greater Los Angeles area.
There has been spectacular population growth in recent years – in 1930 the number of bodies was 2bn, by 1960 it had reached 3bn. At the current rate of growth it is expected to hit 9bn by 2045. On the day I was born in 1962 there were 3,209,507,604 people about (including me).
Can the planet cope? Do we have the resources we need to survive?
We are pretty good at adapting, but resources are finite. As an example these people will all need fresh water – and of the water on the globe 97.5 percent of it is saline – of the other 2.5 percent freshwater, two-thirds of it is frozen…
Oil will almost certainly run out – so we do need to find sustainable fuel sources. Solar and wind are looking pretty good?
In the short term we may need to sort some housing out. Current estimates suggest that 134,000 new homes were built in the UK in 2010, the lowest number since World War II. It is reckoned that 230,000 new households are being formed every year. By 2025 there will be a housing shortfall of 750,000 in England alone. If this is replicated across the world, we will have a lot of people squeezed into fewer and fewer buildings?
There is just one thing though – who was the 7bn’th person. They deserve a prize!
