That kind of fallacy is called Argumentum ad Hominem. It means the argument is addressed to the person; attacking that person instead the issue. There is an irrelevance because the argument is against to the person making a claim, rather against to the claim itself. An example is judging a person's social status or attitude, like calling his strategies aren't effective to finish a certain task because of his untidiness and laziness.
It is important to start practicing alternatives to non-renewable resources because we are running out very quickly and they will not be around forever. Hope this helps :)<span />
<span>Short-term memory is the part of memory that is typically used to simply store information for a short period of time, milliseconds on average. Working memory, in comparison, allows for us to take these short-term memories, recall them, and manipulate them in ways that short-term memory is incapable of handling.</span>
