Inference or absolution? The case for protecting Blue Whales now!

by simon

If we wait for proof to make environmental decisions, we’ll fail to reverse the sixth mass extinction and will rapidly destroy our chance of survival. Proof is a panacea, because ecosystems are too complex for science to every understand completely.

Ecology is also complex because species are constantly being driven to extinction:

“It would be like if you were a particle physicist and you had to get up every morning worrying that the Higg’s particle went extinct”, John Harte, Berkeley University.

We have to accept that stabilisation of ecosystems and resilience-building are prerequisites for a habitable Earth, so we cannot study today’s ecosystems, because most are in a state of chaos. All we’re doing is confusing ourselves, by coming up with an assortment of examples of the way things aren’t working. Each observation is only an iota and the further we move from steady stable-state ecosystems, the more deranged our overall assumptions become.

The fact that perhaps as many as half a million Blue Whales were once able to survive in the world’s oceans, is a reason they must have been part of the system that makes ecosystems stable. This is the largest animal that ever lived on Earth and no animal, let alone the biggest, can survive long in an environment that isn’t stable. The fact is, human survival integrates with the survival of Blue Whales and the supporting cast of animal life on our planet. We are long past the point where science can deliver us the proof we need to make decisions, other than to simply protect wildlife. Drawing by Simon Mustoe.

In short, there is no way to release ourselves from the punishment we will face from breaking Earth’s systems, if we wait to understand the mechanisms behind what makes ecosystems work. There will be no absolution for our sins, unless we can start making common sense decisions based on inference–we have all we already need to know, about what constitutes a working environment. It is one that is rich in animal life.

This is why I like studies like this one about Blue Whales and the model animation, below.

These aren’t real data. The authors didn’t satellite track whales, they have built a model and inferred the behaviour of a Blue Whale (blue dot) against the movement of vessel traffic (dark red dots). It is precautionary guidance about what will happen to ecosystems, if we do not remove obstacles to wild animal behaviour.

The difficulty only comes when this is placed in front of decision-makers.

Scientists will always want more evidence to improve the model, because this is their job, but conservation scientists can easily become stuck in a paradox of their own making, when researchers lust for more data and decision-makers think this means an absence of evidence … governments use uncertainty as an excuse to delay decisions, even though absolute proof will never be achieved.

Even if we wanted to understand how Blue Whales behave around ships, we will never know, because there are hardly any Blue Whales left. According to the International Whaling Convention (IWC), an estimated 362,879 Blue Whales were killed[2], or a reduction to just 0.07–0.29% of natural levels. The ecosystem has been changed from one of some stability, to one of chaos so any present-day study of Blue Whales will simply reveal some random variation of the reality that’s needed, to stabilise ocean processes. Blue Whales are, after all, conspicuous components of ecosystem structures that need the animals to stabilise, that create the weather that supports our economies. These impacts are on a continental and even global scale.

This is just common-sense and it applies to all animals, not just Blue Whales. It makes no sense to delay decisions to protect wildlife. This is why inferring risk and committing to a calculated effort to recreate wild animal populations is our only hope for maintaining a habitable planet.
