Explanation:

Don't throw paints, oils or other forms of litter down the drain. Use environmentally household products, such as washing powder, household cleaning agents and toiletries. Take great care not to overuse pesticides and fertilisers. This will prevent runoffs of the material into nearby water sources.

Don’t throw litter into rivers, lakes or oceans. Help clean up any litter you see on beaches or in rivers and lakes, make sure it is safe to collect the litter and put it in a nearby dustbin.

1. Instead of using the air conditioning when it gets hot, turn on the fan. It will only take about an hour to cool down your house, saving you money and water.

2. Buy recycled paper products as opposed to “virgin” paper products. Recycled paper requires far less water than brand new paper production.

3. Insulating your pipes will not only save you money in energy costs, you won’t waste water when you’re waiting for it to heat up.

4. If you accidentally drop an ice cube, don’t throw it down the sink, use it to water a house plant.

5. Collect the water that you run while waiting for the water to reach your desired temperature and use it to water plants. This same idea applies for shower and bath water too!

89 people per day
