What can we as individuals do?

We as individuals can do alot, in fact we do. We recycle all our rubbish, well at least i do at home. We recycle glass, paper, and metal. Also we can have an impact as individuals by reducing the amount of water we use by switching off taps when they are not needed and using rain water to feed the plants rather than using clean drinking water from the taps.
We can also reduce the amount of electricity we use, for example by not over filling the kettle and turning off appliances when they are not in use, and maybe just turning them off and finding other things to do.
Also the amount of cars on the road has a major impact on sustainability as there are too many and this is mainly due to people travelling alone. Whether this is to work or elsewhere. This could be reduced by individuals if they shared their cars or travelled by public transport. Public transport is not alwasy the most comfortable way to travel at the moment, however it would seem that the government is trying to improve it. An example of this is the Manchester Metro which the carriages are to be replaced by more comfortable and efficient replacements. So it would seem that in the future there may be more individuals travelling in a more sustainably and making a difference.
However even though there are individuals making a difference by doing all of these things it may be worth considering how much of a difference they are making? Does turning off the tap here in Britain mean that in Africa a poor child gets a drink? Does one person getting public transport for a year reduce the emissions of CO2 into the atmosphere to make a significant difference to global warming?
I dont believe so. Therefore it may have to be considered that individuals can make a small difference, however there would have to be an awful lot of people doing these changes to make a significant impact and without this happening there would not be much change.
