Description: Measles is an air-born infection caused by a paramyxovirus, mostly common in early childhood. In the present day, measles is considered an extinct disease in most parts of the world. According to WHO, in 1980, before widespread vaccination, measles caused an estimated 2.6 million deaths each year. However, in the recent years, the once eradicated disease started resurfacing in countries like New Zealand, Australia, and United States (CDC). It is one of the leading causes of death among young children even though a safe and cost-effective vaccine is available (WHO). [show more]

Description: Rockweed is a brown algae found on rocky shores. The most common types of rockweed are within the genus Ascophyllum spp. and Fucus spp. (the latter is shown to the left). They grow slowly and can live from 3 to 15 years before breakage. Rockweeds have fronds that bear air bladders. These 'airbags' help the algae to stand up straight under water. Rockweed lacks true roots, stems, and leaves, and because they lack a vascular system, absorb dissolved nutrients directly through the blades. Rockweed attaches to rocks with a disc-like “holdfast”, and regenerate fronds from remaining holdfasts after a natural disturbance that removes upright fronds. [show more]
Description: Namibia is known for its arid climate and the flora and fauna that have adapted to these conditions over many generations. The livelihoods of most people depend directly on the land. Therefore, a large portion of Namibia is used for agriculture, natural resource extraction, and tourism. The country mainly exports raw materials and imports most of its goods and services.
