Salmon Confidential Story at-a-glance
Salmon Confidential draws back the curtain to reveal how the Canadian government is covering up the cause behind British Columbia’s rapidly dwindling wild salmon populations: fish farms
In British Columbia, pacific salmon are an essential species for the ecosystem. They fill hundreds of streams and rivers, feeding hundreds of species, including humans. Since the early 1990’s, salmon numbers have rapidly dwindled, coinciding with the introduction of farmed salmon pens
Fish farms breed pathogens that can spread like wildfire and contaminate any wild fish swimming past. Wild salmon that died before spawning have tested positive for a number of salmon viruses, including the highly lethal “salmon influenza”
Farmed fish, purchased in stores around British Columbia have tested positive for at least three lethal fish viruses, including the dreaded ISA virus (aka salmon flu), salmon alpha viruses, and Piscine reovirus, which causes the salmon to have a heart attack, preventing them from swimming upriver
I recommend buying locally-grown foods, and wild fish only. Fish farms are a breeding ground for disease and toxic waste, and produce fish of inferior quality. Due to the dramatically increased disease risk—a natural side effect of crowding—these animals are further contaminated with drugs, and in the case of salmon, synthetic astaxanthin, which is made from petrochemicals that are not approved for human consumption
5 acre abundance on a budget
This provides a clear demonstration of how a mundane piece of land can be turned into a pleasant near-self-sufficient home with excess product for sale. The land value must have increased phenomenally over a few years, but that's irrelevant, because we would never want to sell it.
I have a dream that Laos farmers can receive education in these techniques, which are not complicated. They would very quickly (3 - 5 years), improve their standard of living, as well as expanding the country's limited range of home-grown food whilst disposing of the food shortage problem.
If dam engineers were to learn from this video alone, we would have far less environmental destruction.
This is an excellent demonstration of how to work with nature instead of against it.
I hope you enjoy it as much as I did.
By the way, over 800 comments after just 3 days - it is an excellent.

Swale (Wikipedia)
The swale concept has also been popularized as a rainwater harvesting and soil conservation strategy by Bill Mollison, Geoff Lawton and other advocates of permaculture. In this context it usually refers to a water harvesting ditch on contour. Another term used is contour bund.
Swales as used in permaculture are designed to slow and capture runoff by spreading it horizontally across the landscape (along an elevation contour line), facilitating runoff infiltration into the soil. This type of swale is created by digging a ditch on contour and piling the dirt on the downhill side of the ditch to create a berm. In arid climates, vegetation (existing or planted) along the swale can benefit from the concentration of runoff. Trees and shrubs along the swale can provide shade which decreases water evaporation.
