摘要或動機

In Swakopmund we have a problem with seaweed deposits on our beaches. Tons of seaweed are throwni away yearly. The reason I did this project was to see if the seaweed on the Namibian coast can he used instead of just being thrown away.Seaweed is a rich source of natural minerals and vitamins such as calcium, potassium iodine and also Vitamin A, BI and K. The seaweed on our coastline cannot he eaten as the salt content is too high. Seaweed is a marine algae that works like a sponge absorbing nutrients and minerals from the water.I extracted agar (a jelly) from red seaweed called(GracilariaVerrucosa). I dried the agar and seaweed, and I also grew mushroom spawns and bacteria on the agar plates. Secondly, I researched the possibility of using kelp (Laminaria Pallida), as fertilizer and livestock supplements. The unemployment rate in Namibia is very high. With adequate financial resources and proper marketing, seaweed can he used to increase the economy. We can market the agar to pharmaceutical and cosmetic companies, and also supply it to the university for students in Biology to grow bacteria and other micro organisms. The ferti lizer can be used to boost agriculture in Namibia. It is cheap and the farmers will he able to p1 ant vegetables with better nutritional value.All this was done to promote of biggest natural resource to create more work and to find a way for the less fortunate to create a better life for themselves.
