Yes, I have capacity to catch 8000 litres. I have ability to green garden, grow veggies which have positive effects for carbon usage, food production, cooling our garden environment etc etc - look at Biodynamic organisation australia and their work to determine long term benefits of greening your area. I also have rainbank davey system which switches house to tank water when tanks have capacity. There is lots an individual can do environmentally.
It is better to bath and drink rain water. It is better to grow some of your own food. It is better to have a green verge around your house. Eat locally, I used all my own green veg and herbs during Xmas.
Read Ringing Cedars books to find out about garden revolution in Russia.
