(a)
Interpretation:
Based on Rudy Baum’s editorial thoughts on nuclear waste, mining, effects on climate change, cost and human fear has to be explained.
Concept Introduction:
Global demand for energy is increasing day by day. In order to meet this demand we need safe and sustainable energy sources. Fossil fuel is non-renewable and cause environmental pollution, so it cannot be used in future. The lion’s share of today’s energy is obtained from nuclear power plants. But difficulty in the waste disposal is the major problem of this method. Solar energy, hydroelectric power can be future’s major energy sources. Several researches are going on in this field for the generation of clean and safe energy.
(b)
Interpretation:
Content in the cartoon has to be explained.
