The diagrams illustrate the present system of supplying water to shops, households and factories in Australian cities, with proposed future changes.

Overall, it is clear that in the future no water will be discharged into rivers.  Instead, water treatment plants will treat waste water and storm water, ready for recycling to consumers in the cities.

The first stage in the present water supply system is the collection and storage of water in dams.  This pure water is then delivered to factories, households and shops in the cities.  Waste water then goes to a treatment plant, after which it is discharged into rivers.  The excess of storm water in cities also goes into rivers.

In the future,  while the supply of pure water to the cities is expected to remain unchanged, a major change will occur in the treatment of waste and storm water from the cities.  Waste and storm water will go to the water treatment plant, and no water will enter the rivers.  It is planned to return the treated water to the cities as pure water after treatment.

It is true that across the world, a few languages have come to dominate, resulting in a loss of diversity in the languages in which people communicate.  While this has some positive aspects, I believe that it is a largely negative trend.

On the one hand, there is one major positive aspect of the growth of a small number of languages which are in use worldwide. This is the transmission of knowledge as people are enabled to communicate outside a small community.  As a result of the dramatic socio-economic changes in recent decades, English, Spanish and Mandarin Chinese are now used internationally. The majority of English speakers, for example, do not have English as their first language.  However, they have learned English in order to do business, to work, to study or even to acquire a visa. In a multicultural society like Australia, the best way to integrate into society is to express oneself in English. 

On the other hand, when a language is lost, then an important part of a culture is lost.  The modern world is shaped by such things as advances in technology and the migration of labour, as people seek to have a better life.  Yet the cost of greater social mobility is often the abandonment of traditional communities and a way of life in which people lived in harmony with one another.  Within the community, everybody spoke the same local language.  A local language formed a bond between generations, handing down oral traditions in the form of stories and local knowledge.

In conclusion, I believe that the world is a poorer place culturally with the disappearance or decline in use of many languages with the growth of a globalised culture and economy.
