1.Earth Hour is something Australia organised and it is mainly just switching off all the lights in the entire city that is doing it.Singapore will also be holding Earth Hour and the entire city is given the choice of saving the Earth or destroying it.
2.It is held on this Sunday(I think).
3.People probably organise it as means of stopping or at least delaying,the Earth's total annihilation.
4.Most people will be switching off their lights while some others will still have it on as a sign of saying they either do not know,do not care or do not want to do it.
5.I don't know,probably play computer games,read books or just sleep together or maybe watching those faint stars.
6.Earth is also facing the problem of pollution,be it by land,water or air,as smoke produced from cars,people throwing things into the sea and others burning their unwanted trash.Also the greenhouse effect and global warming are also rising problems.
7.For air pollution,we could reduce the use of private transport and increase the use of public transport such as buses,to prevent much of air pollution.
