Saving Water?

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.

Hmmm I guess so. Well, in that case I will do everything I can - even I can make a difference I hope.

If you're serious about saving water, you should look into the ACQUS water reclamation system, an ingenious household gadget that allows you to use used bathroom sink water for flushing the toilet. If you consider 40% of household potable water goes down the toilet, there might be something to this

Hmmm that's true, I'll look into it, thanks

It is important to devise good ideas and take concrete steps for solving this enormous problem - other details will be improved step by step.

I have a showerdome on my shower which helps me reduce water usage. Given that the shower is where most water is wasted, we had one installed because of mould and mildew, but now I turn down my hot water temp because the shower cubicle stays warm and because it stays warm I can turn OFF the water while I wash hair and body and I don't need an exhaust fan because we get no steam in the bathroom. The best thing about it is that the kids are also turning off the water in the shower because they don't get cold and it is teaching them saving H2O as well. We save bucket loads of water.

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.

Very good topic and good article. Saving natural resources is essential. It takes awareness and effort of each individual and there are many ways ...

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.

there is a lot of reasons to collect it also check out this

managing the water supply on this planet whether it's potable, fresh or salt is one of the many important things we need to focus on YESTERDAY let alone today and in the future.

Right on, Beckya!! Water supply, the pure kind, is said to be the weakest link in our ecological chain.
"Research from Murtaugh and Schlax at Oregon State University shows that a hypothetical American woman who switches to a more fuel-efficient car, drives less, recycles, installs more efficient light bulbs, and replaces her refrigerator and windows with energy-saving models, would increase her carbon legacy by 40 times if she has two children."
I would think that the above also applies to future water.
