	c) Water should be conserved as it's crucial for life and agriculture.		d) Using water indiscriminately does not affect the environment.

Q.5	Why are oceans considered the "lungs of the Earth"?
	a) Because they produce a significant portion of the world's oxygen through phytoplankton photosynthesis		b) Because they are a source of clean air for the planet
	c) Because they release carbon dioxide into the atmosphere		d) Because they help in the transportation of oxygen to land-based ecosystems

Q.6	In a coastal town, residents have noticed a significant increase in the intensity and frequency of storms and hurricanes over the past few years. What could be linked to the observed stronger and more frequent storms and hurricanes?
