"the number of people suffering food crises as a result of natural disasters has tripled in the last thirty years"
Explanation:
2 The elimination of runoff can reduce contamination of surface water with pesticides, sediment, metals, and fertilizers. By reducing stormwater runoff, rainwater harvesting can reduce a storm's peak flow volume and velocity in local creeks, streams, and rivers, thereby reducing the potential for streambank erosion
3 The epicenter is the point on the earth's surface vertically above the hypocenter (or focus), point in the crust where a seismic rupture begins.
4 Repeated earthquakes on a slope lead to a deformation of the materials that make up the slope. This can lead to a decrease in the intrinsic characteristics of materials that tend to oppose movement and thus facilitate the development of an overall break in the slope
5 People must be made aware of what natural hazards they are likely to face in ... and education programs about natural disasters be made a national priority.
