• Nearly all major cities were built on a river.
• Rivers were traditionally used by city dwellers for transport, fishing and recreation.
• Industrial development and rising populations later led to:
  • more sewage from houses being discharged into the river
  • pollution from 31. on the river bank.
• In 1957, the River Thames in London was declared biologically 32.

• Seals and even a 33. have been seen in the River Thames.
• Riverside warehouses are converted to restaurants and 34.
• In Los Angeles, there are plans to:
  • build a riverside 35.
  • display 36. projects.
• In Paris, 37. are created on the sides of the river every summer.

• Over 2 billion passengers already travel by 38. in cities round the world.
• Changes in shopping habits mean the number of deliveries that are made is increasing.
