To continue it has an area of about 30,000 square kilometres and nearly 11 million people.
30,000 square kilometres means about 300 x 100 kms, or about 187.5 miles long x 62.5 miles wide. So, at what point will the population continue to be sustainable? That's for nearly 11 million people, who have to be fed, housed, heated, sewered, transported and as posited above, buried or disposed of in some way.
It's not just a case of how many people you can squeeze a meter apart either. I lifted the following from a site on related to a supportable population. It takes 900 tonnes of water fro example to grow one tonne of wheat. These days it takes a joule of fossil fuel energy to provide a joule of food energy. And if everybody wanted to live at the American level, we'd need four earths.
"Joel Cohen, the Rockefeller University population biologist, argues in a 1995 book (How Many People can the Earth Support?) that it isn't a question like "How old are you?" which only has one answer at any one time. Cohen argues that you could fit one billion people each a metre apart, into a field 32km square. So everybody in the world would fit easily into Yorkshire. But it takes 900 tonnes of water to grow a tonne of wheat, and there is only so much water, so much land and so much sunshine. Human action has its own "ecological footprint"; there has to be so much land to provide food, clothing, shelter, medicines, building material, fresh air and clean water for any one human. It takes, according to some calculations, 2.1 hectares of land and water to provide for one average human. The important word is: average. The American footprint is about 10 hectares. So if all humans lived at US standards, we'd need another four Earths."
and from another site, the amount of water to produce a pair of jeans -
"Doing a bit of research online I found that the figures quoted on different websites varied between 2000 and 6000 litres of water for just one pair of jeans. I also read that to stonewash a pair of jeans takes an additional 20 – 750 litres! Just to put this in perspective the UN recommends that people need a minimum of 50 litres of water per day for the most basic needs such as drinking, cooking and sanitation. Millions don’t even have that."
