1.en.12 Some questions raised by population growth: urban development and sustainability

When dealing with large figures we should be aware of the difference between American and British.

A thousand is always 1,000 and a million is always 1,000,000. After that things become less clear.

In the USA:  1,000,000,000 = a billion.

In Britain : 1,000,000,000  = one thousand million;   1,000,000,000,000= a billion

Anyway, keep the American way of dealing with billions and try to guess the answers of this questionnaire before watching a video to find out answers

HOMEWORK: Tuesday 18th October.  Answer the questions in your notebook and post them to the blog one answer per person. Remember the rules, do not repeat any answers your classmates have already posted. (only if you think the answer is wrong or to correct spelling or grammar. Also answer questions in order.
