Doesn’t every little bit help? And does this hobby help create a mindset of sustainability, recyclable, or reuse for our water environments?
Every little bit probably helps, yeah - but only if it adds up to something significant. Otherwise it would be so insignificant that it would not matter.
I am also unsure if this hobby help create a mindset of sustainability etc., given the lack of information/false information that may often be purported.
Take collecting from the wild as an example. There are many marine organisms that we absolutely must conserve if we want to keep them alive, and some habitats should just not be disturbed full stop. But as much as buying used equipment contributes insignificantly to sustainability, so does collecting certain fish contribute insignificantly to reducing their populations.
For example, percula clownfish. A lot of people are up in arms about collecting them from the wild, when a report from just 5 years ago estimated 13 to 18 million individuals in the wild, and that is a conserved estimate. So even if we collect So even if we collect a thousand percula, that is still less than 0.01% of their wild populations.
When these sort of information becomes clear, and they also do, it significantly hurts efforts to actually try to couple the hobby with sustainability, as those who pushes back against captive breeding efforts and all that receives ammo to go even more all out. Given that a lot of efforts are too heavy handed and extreme. "No! Ban everything! No, everything has to be captive-bred!" Etc.
So tldr; Every little bit helps insignificantly and at some point it is materially pointless. The hobby SHOULD be coupled with sustainability, but instead often couples with illogical decisions and/or determinations, which backfires and so in reality it does not actually help create the right mindset a lot of the time.
When people become defensive, that does not help change their mind. And when they are
rightfully defensive because yeah, what they are facing is actually illogical, then that makes everything even harder.
