When going out during holidays check that all your taps are shut properly. The more water we use, the greater the strain on treatment systems. During festivals avoid using water indiscriminately. Try to clean up your home, office, by using less water. Use water saving devices or a water efficient toilet.
Parties are easier to organize and clean up if everyone brings cutlery or dishes.
For large gatherings, rent instead of using disposables. Much of the paper in an office ends up in the garbage. Place a bin for the used paper that can be recycled later. Don't throw away empty toner cartridges from printers and photocopiers. Don't print hard copy from the electronic mail system at work unless you have to.
