Welcome to the Army Rumour Service, ARRSE

The UK's largest and busiest UNofficial military website.

The heart of the site is the forum area, including:

  1. Sounds like I need to get on with my "Riddle of the Sands" fan boi trip.

    And what kind of religion restrict them to enforce sand islands with concrete infrastructure, like Chines do in East-China sea?
     
  3. It's a beach resort. If you cover the beaches in concrete you sort of defeat the purpose of having it.

    There's a Wikipedia article on the island which can give you some background. They've tried all sorts of different things. However, civil engineering is a bit more difficult then just tossing some concrete blocks around. The type, size, and texture of the sand, the degree to which the bottom slopes away off shore, the prevailing currents, the winds, the direction of storms, the presence of ice, the use to which the land is put, the beach vegetation, and many other factors all play a part. What works in one place can simply make the problem worse in another. There is some suggestion that the building of a causeway to the island a century ago may have contributed to the problem by changing water circulation.

    There's a small core of glacial till to the island. The sand spits extending out from it however have never been stable. It was the development of the island as a beach resort early in the last century that created interest in stabilising the sand spits to use them for tourism purposes.

    There are a number of tropical holiday destinations which have artificial beaches using sand which is pumped up from offshore or brought in from elsewhere. Those beaches only exist so long as fresh sand is brought in to renew them.

    Depends from tastes. There are rather pretty concrete beach in Ploche, Montenegro.

  5. US have a Government Global Water Strategy. Apparently written by what remains of the State Department.


    https://www.state.gov/documents/organization/275842.pdf


    There is a growing global water crisis that may increase disease, undermine economic growth, foster insecurity and state failure, and generally reduce the capacity of countries to advance
    priorities that support U.S. national interests. To address these challenges and contribute to a healthier, safer, and more prosperous world, the United States will work to support a water secure world where people have sustainable supplies of water of sufficient quantity and quality to meet human, economic, and ecosystem needs while managing risks from floods and droughts. This work will be guided by four interconnected strategic objectives:
    ● Increasing sustainable access to safe drinking water and sanitation services, and the adoption of key hygiene behaviors;
    ● Encouraging the sound management and protection of freshwater resources;
    ● Promoting cooperation on shared waters; and,
    ● Strengthening water-sector governance, financing, and institutions.
    To achieve these objectives, the United States will provide technical assistance; make targeted investments in sustainable infrastructure and services; promote science, technology, and information; mobilize financial resources; engage diplomatically; and, strengthen partnerships and intergovernmental organizations. This will be achieved through direct assistance to countries, scientific and technical engagement, and support to international organizations, institutions, and partnerships. Foreign assistance can only provide a small portion of the funds needed to meet water and sanitation needs globally and must be used strategically to mobilize financial resources from host country governments, the private sector, and capital markets, where appropriate. The United States will focus its efforts on countries and regions where needs and opportunities are greatest and where U.S. engagement can best protect our national security interests. This includes high priority countries designated under the Senator Paul Simon Water for the World Act of 2014 for October 1, 2017 – September 30, 2018. Overviews of countryspecific plans for implementing this Strategy in high priority countries and geographic areas are appended to this Strategy.

    Ha! Do you remember what was called as 'most seriouse nationwide threat' by George Walker Bush in his speech in the 4 September 2001?
    Of course, you don't. It was a 'passive smoking'.
    And yes, just for your and @scalieback education:

    It is you, who have no any 'arguments' but sh-t throwing.

    Crayon somewhere else. Grown ups talking.
     
  9. Too bad they're not able to do that themselves.
     
  10. The main problem in the US is poor agricultural practices. However, the farmers don't want to hear about it, and the politicians don't have the guts to enforce it.

    In Lake Erie the main source of algal blooms is from a few minor rivers in the US, mainly at the western end. One of those is shown in a photo in the article.

    The river at the top is the Detroit River. The one at the bottom left is the Maumee. The green bloom is not the result of pollution from the city of Toledo, it's from farms further upstream. Currents in the lake carry the water in a spiral fashion, carrying the pollution across to the opposite shore (as seen in the photo). The distribution will vary according to the wind and weather, but generally the blooms are concentrated on the southern and western sides of the lake.

    The main issues are twofold. One is corporate livestock farms (particularly pig farms) which can be huge in the US. They produce far more manure than they can use in a sensible manner, so they just spread it out on the fields and let the rain wash it away into the rivers. Wet manure is heavy, so it isn't profitable enough to sell it over a broad enough area to avoid these sorts of high concentrations. There are ways of composting the manure to get rid of the bulk, but that costs money rather than makes money so it doesn't get done very much.

    The other issue is poor use of chemical fertilizers. They're over used, used too close to waterways, the farmers plough right up to the edges of streams (which causes more run-off), and they're often applied at the wrong time (and so get washed away instead of being absorbed into the soil). Chemical fertilizer is cheap enough that using it efficiently simply isn't high on anyone's priority list.

    In Canada, the structure of the livestock industry means that farms tend to be smaller, with more of the corn and silage being grown on the same farm, so manure is less of an issue. More importantly, the province has people who get out into the field and put effort into working with farmers to change their practices to ones which cause less of a problem.

    Prevention is not really expensive, but it takes people who have the knowledge and it takes a government apparatus who can sustain an effort over the long run instead of throwing up their hands and saying it's God's will (not a whole lot different from the sort of "Inshallah" you hear in certain other parts of the world).

    Also there are alternative ways. You can use aerators to enrich water with oxigen and get much more fish.
