There is no need to destroy an ecosystem for the selfish needs of humans. Time we stopped breeding and destroying the only planet we have to live on.
Population control will save the world from most of its problems, sand, pollution, global warming etc.
Recycling? Just a thought...
....be a mad big hole.....just a thought, the whole Middle East would be about right. we could call it the sea of tranquillity.
That is a plot for a Goon Show script right there.
Geez, you must be bored ;-). but thanks for the interesting stats
Hey I thought DB Breweries were making vending machines that turned beer bottles back into sand? One way we can help, meet me at the bar! TGIF!
Its all humanity that causes the problem.We need too much of any commodity!We are to many and keep getting more.Has anybody thought of how to turn this development around?
I fathered 2 daughters and now have one grandchild, there will be no more - that should help !
It wouldnt make any difference at all. Also, sea levels are rising only about 1.3mm a year and not increasing at present. The 1-2 metres in the article are not put in a time frame. Sand extraction is essential to our wellbeing and we need good science and less superstition to regulate the various uses we need. Seabed extraction will progressively provide more of our needs.
So coastal scientist Jim Dahm, claims we are expecting one or two metres as a minimum of sea level rise.Yet global sea levels are only rising 3 mm per year. At that rate it will take over 600 years to rise 2 m.
He means since preindustrial times. Mean global sea level has already risen 30cm since then, and a further 70cm is predicted by 2100 under the RCP8.5 scenario (emissions continue to rise throughout the 21st century).
Yeah I saw that as well. No time frame was quoted but as you state, we are talking centuries folks.
If all the sand is gone how will we write love letters in the sand?
It almost doesnt matter what the per annum sea level rise is at the moment (although it is worrying enough). The kicker is that both theory and measurement reveals that there is an exponential increase in the rise at a far greater rate than any time in the realizable past.
I doubt his were expecting one or two metres as a minimum means that at all, Surly. Over the past 25 years, satellite data has shown SLR to be constant at 3mm/yr. Continuing for another 80, should see around another 24cm. Significantly less than 70cm and a fraction of what Mr Dahm is expecting.
predictions and reality are always different ,, ther e is no excellerated rise in sea levels
Not sure youre down voted. Perfectly sensible comment.
actually it is the opposite
The fear of a shortage of sand for concrete is not new. Over fifty years ago I remember a Canterbury company transporting stone to the North Island to a special crusher to test the viability of certain types of stone being crushed into concrete quality sand.Should this system come to pass at this time we would see noise complaints and dust complaints and then of course there would be complaints over truck movements. Whatever decision is made there will always be those that complain weather it effects or not.
