Even if everyone practiced all the local green reforms, but the human population kept growing, the mass of people would overwhem everything. So along with green technology and green lifestyles, we should give every woman the legally protected right to decide if and when to conceive and birth her children, which most often results in no more than 1, 2 or 3 children per family. Then, as the human population reduces, the big cities will shrink to towns and villages and their water will come from nearby brooks and creeks, plenty for the smaller population.

A relentlessly growing population will eventually demand more water than the biosphere can provide. A smaller and stabilized population will have all the water it needs.

I am not sure about the grass roof though, isn't it a bit risky if I don't have the ideal slope for it?

Thanks for your opinions.

From the Journal 'Nature' , "80% of people live where river waters are degraded or depleted, and their water security is threatened.
Species in 65% of the globe's rivers are at risk of extinction because of lack of water, pollution, and destruction of watersheds. The report documents pandemic deterioration of fresh waters."
Many are in the USA and Europe, and they studied the whole river, not just part of it. Thousands of them around the entire world. Rivers once thought to have been "fixed" are polluted again. Rivers running dry that never did before. What started with the discovery in the 1980s of a few estuary dead zones has increased to over 100, and they are getting bigger in size, too.
The report was only for world surface water (1) and did not get into the fact that most of the rest depend on aquifers that will be dry at or before 2040 (2), like our Ogallala. Also not in the report is the effect the pollution and depletion of surface and aquifer water will have on food production.
Noting that irrigation gives six times the yields, this will be a large reduction in agricultural output (3) along with the lack of pure water supplies. Global warming only makes it worse (4), as does the increasing over-population(5). Peak oil also affects agricultural output and distribution(6).
Six things that will profoundly affect the world of 2040, preceded by other effects such as economic depression from increasing prices, and lack of jobs, with instability.
They all tie into each other.

It's certainly good to save water, but as Val and I keep on trying to explain, it is the ever-growing human population, now 7 billion and counting, that is both depleting and polluting the limited number of places where fresh water is, or was, available -- but not for much longer if the human population keeps on growing and refusing to recycle its waste products, instead dumping growing tons of garbage, sludge, junk, chemical waste, smoke and fumes into the atmosphere, into growing mountains of landfill, and out into the ocean, where several huge "garbage patches" are growing while birds and mammals are eating it and dying.

As the human population grows and pumps more smoke and fumes up into the air, which artificially warm the climate and cause ever more evaporation and precipitation, the sunny days are becoming droughts, punctuated by ferocious storms and floods as the biosphere struggles to heal itself.
