Answer 2

We need to use resources carefully because of the following reasons:

2.Though we have resources easily available today but if the use of resources just keep increasing then a time will come when people will fight for resources.
3.Resources need to be conserved as the time taken to utilize this resource is very less while the formation of resources like fossil fuel takes millions of years.
