Answer:
your answer
Explanation:
(1) Dams store water, provide renewable energy and prevent floods. Unfortunately, they also worsen the impact of climate change. They release greenhouse gases, destroy carbon sinks in wetlands and oceans, deprive ecosystems of nutrients, destroy habitats, increase sea levels, waste water and displace poor communities.
(2) A storehouse of minerals: Most of the minerals in the world are found in plateaus. The extraction of minerals in plateaus is relatively easier on plateaus than mountains. The major portions of industrial raw materials are obtained from plateaus.
(3)February 2005) Ravi is a weathered fisherman in Chennai, India, who survived the recent Indian Ocean tsunami. But weeks after the event, he speaks of what might be the tsunami’s biggest victim along Chennai’s 25-kilometer coastline: the livelihoods of the more than 40,000 fishing families who live there.
“We never thought it was possible,” he says. “But we are poorer now. We had no education. No drinking water. No toilet. No drainage. No health care. We were poor and exploited. Yet we survived, protected by the sea that gave us a living. But now, we face an uncertain future with all the basic socioeconomic inadequacies staring us in our face.”
