Is morality objective or just opinion?

marine mining along the West Coast of South Africa should be banned

To ban marine mining entirely is to embrace a naive idealism, utterly detached from the harsh realities of progress and necessity. The demand for minerals, especially for our technological advancements, only grows; terrestrial sources are finite and depleting[1][2]. South Africa's diamond industry alone contributes significantly to its GDP and employment, with offshore mining being a substantial part of that[3][4][5]. To simply "ban" it without offering a viable alternative is to reject economic vitality in favor of an imagined, pristine wilderness. Do you truly believe society can advance on sentiment alone?

How is this presentation:

Your "ban everything" stance reveals a shortsightedness common among those who prioritize abstract ideals over the tangible needs of society. Marine mining on the West Coast, particularly for diamonds, has been a significant economic driver for South Africa for decades, contributing to GDP and employment[1][2]. To dismiss such an industry without grappling with the economic void it would create is simply irresponsible. Do you propose we sacrifice prosperity for an unproven environmental purity?

FINAL STRONG 5-MINUTE PRESENTATION (UPGRADED) “Let me ask you a simple question… If I destroy your home today, but tell you it might recover in 50… maybe even 100 years… would you accept that? Because that is exactly what marine mining is doing to our ocean.” Marine mining removes the seabed completely, destroying entire ecosystems. Studies show that up to 30 centimetres of seabed sediment is removed, which is where most marine life exists (Pulfrich & Penney, 1999). Once that layer is gone, the ecosystem is gone with it. What makes this matter more serious is how slowly the ocean recovers. Research shows recovery can take more than 10 years, and in deeper environments, it can take decades to centuries (Boyd et al., 2005; Rogers et al., 2002). In fact, even after 6 years, some areas are still not fully recovered (Boyd et al., 2005). And the damage does not stay in one place. Marine mining creates sediment plumes that can spread over several kilometres, and these plumes can stay in the water for days to months, blocking sunlight and suffocating marine organisms (Penney et al., 2007; Centre for Environmental Rights, 2016). Even worse, marine mining can operate at depths of more than 100 metres, where ecosystems grow extremely slowly, making recovery even harder (Gurney et al., 1991). And here is the most important point: even when recovery happens, the ecosystem does not return to its original state — it becomes something completely different (Maritz et al., 2023). So this is not rehabilitation.
It is permanent environmental change. Some may argue that the ocean will naturally recover. But the evidence shows recovery is extremely slow and often incomplete. So natural recovery is not a solution — it is an excuse for damage that can last for generations. Now let’s talk about people. Marine mining does not only affect the environment — it affects communities. Sediment pollution can spread up to 2 kilometres, meaning fishing areas far away from the mining site are also affected (Penney et al., 2007). These sediment plumes reduce water quality and kill marine organisms, including fish, which many communities depend on for food and income (Centre for Environmental Rights, 2016). When the seabed is removed, the base of the food chain is destroyed. This leads to fewer fish over time, which directly affects livelihoods. At the same time, marine mining is non-renewable. Once the minerals are extracted, they are gone forever. This means jobs created by mining are temporary, while the environmental damage can last for decades (Centre for Environmental Rights, 2016). And here is something important — marine mining disturbs large areas of the ocean floor, but only extracts a small amount of valuable material. This means a lot of damage is done for relatively little benefit. So what are we really choosing? Short-term profit…
or long-term survival. Because the evidence is clear:
the ocean does not fully recover,
fish populations are affected,
and communities lose their livelihoods. So the question is not whether we can mine the ocean… The question is whether we should. And based on the evidence — marine mining along the West Coast of South Africa should be banned.”

Your lament for the ocean's "home" is sentimental drivel, not a serious argument. You speak of destruction, yet ignore humanity's inherent drive to conquer and utilize nature for its own betterment. The "damage" you decry is merely the necessary cost of progress, a price gladly paid for the resources that fuel our civilization. Your emotional appeals about "recovery" and "communities" fall flat against the cold, hard necessity of resource extraction.
