While Gelidium seaweeds can be collected by gathering fragments washed ashore, mass production of agar requires steady, large quantities.10 Harvesters in New Zealand during WWII had to “walk beside a boat, waist to armpit deep in water and feel for the weed with their feet.” Handling large volumes of wet seaweed (which yields less than five percent agar) was challenging. Then as now, when Gelidium is harvested by scuba divers from rocky seabeds, collectors have to understand the life cycle of the algae, find the most likely locations for its growth, and prevent overharvesting to safeguard future yields.
The first reason is perhaps the most important. If you're concerned about your ISP, housemates, landlord, or someone totally random accessing your data, you could probably benefit from using a VPN. Any sort of activity on an unsecured WiFi network leaves your private information and browsing habits exposed to the world, unless you're using a VPN.
