It's all like some mad fictional conspiracy!
I can see it now - this is the plot so far: an evil foreign power has decided to take over the world not by military or by financial means, no this is chemical warfare! It is a long term darstadly scheme, they carefully infiltrate and integrate themselves into our government, they stop the building of reservoirs because they would be too easily identified as a source.
They brainwash the population to change to their oral (chemical) contraceptives which are then recycled through our river systems. They introduce their own people through a government agency which they call the EA.
I'll get back to the plot in a minute, we need to cast our hero, maybe Bruce Willis or Daniel Craig (though I would personally favour Homer Simpson), of course our hero would be surrounded by a bevvy of voluptuous beauties.
Back to plot.
The government then manages to sell off most of the water companies to foreign countries which distances them from blame. They encourage abstraction from our rivers and water table, this, apart from enabling their chemicals to be better distributed, lowers the rivers flow and enables them to also to make millions through selling off the old flood plains and dried up carriers.
Only in the news last week it was reported that human sperm levels have dropped by 40%, can this be attributed to this cunning plot?
Anyway enough nonsense, or is it. Has a plot to end the world (as we know it) been identified by a bunch of old farts on FishingMagic?
Let's just go fishing and continue blanking on our deteriorating rivers .....
