Read the following paragraph and choose the correct statement.

Climate change has reduced human security and threatened human well being. An ignored reality

of human progress is that human security largely depends upon environmental security. But on the

contrary, human progress seems contradictory to environment security. To keep up both at the

required level is a challenge to be addressed by one and all. One of the ways to curb the climate

change may be suitable scientific innovations, while the other may be the Gandhian perspective on

small scale progress with focus on sustainability.
