SPACE-SATELLITE-DUST STORM
In this NASA true-colorAqua satellite image released 23 February, 2004 shows a graceful arc of Saharan dust streaming off the coast of northwest Africa and sweeping out over the Atlantic Ocean and the Canary Islands (BOTTOM). Dust storms like this can be both helpful and harmful to different places and ecosystems. The dust acts like a fertilizer for ocean waters depleted of iron and other nutrients that marine plants need to grow, but it can also carry disease-causing bacteria and fungi, which damages coral reefs in the Caribbean. The dust itself can spread to North and South America and cause respiratory distress in people who are sensitive. AFP PHOTO/NASA
