Serious miners are in locations that don't require additional costs for cooling. You maybe should quit mining or only do it in the colder months for the free heat.
Haha that's ridiculous. If we're supporting decentralization of currency through blockchain, then that concept can equally apply to mining that cryptocurrency.
What you are suggesting is that only big centralized operations with cheap electricity and who are in cool locations should mine. That thinking is the opposite of what most cryptocurrencies are about.
