I twist together two lengths of kevlar fishing line that's 0.4mm diameter and rated for 29kg, so combined roughly 0.8mm diameter and ~58kg pull. This is about the sweet spot imo in terms of thickness, slim enough to fit in small routing holes on mainspring housings and thick enough to get a good sized knot when you tie it. It's also pretty close to the thickness of old sinew drawbands I've replaced. The rated strength is definitely overkill but better over than under. In practise a drawband shouldn't experience more than 750g-1,5kg of pull under normal use.

Therefore, the stronger the wind, the longer it blows, and the larger the area of water over which it blows (the fetch), the larger the waves are likely to be.

Notably absent from the debris was plastic from nations with lots of plastic pollution in their rivers. This was surprising, says Egger, because rivers are thought to be the source of most ocean plastic. Instead, most of the garbage-patch plastic seemed to have been dumped into the ocean directly by passing ships.This suggests that “plastic emitted from land tends to accumulate along coastal areas, while plastic lost at sea has a high chance of accumulating in ocean garbage patches”, Egger says. The combination of the new results and the finding that fishing nets make up a large proportion of the debris indicates that fishing — spearheaded by the five countries and territories identified in the study — is the main source of plastic in the North Pacific garbage patch.

The ocean contains unique biodiversity, provides valuable food resources and is a major sink for anthropogenic carbon. Marine protected areas (MPAs) are an effective tool for restoring ocean biodiversity and ecosystem services1,2, but at present only 2.7% of the ocean is highly protected3. This low level of ocean protection is due largely to conflicts with fisheries and other extractive uses.

While Colombia's catch is comparatively small, its fisheries industry enjoys an international market. Tuna fishing is the leading industry, and much of the nation's catch is used for export. Along with tuna, other major catches include shrimp, white fish (snapper, grouper, etc.), anchovy, herring, crayfish, and conch. Shrimp and shark stocks are threatened by overfishing. Aquaculture products include shrimp, tilapia, rainbow trout, cachamas, bocachico, and carp.
