We often talk about the numbers of animals being killed in natural disaster events such as the Australian bushfires, but we hardly notice when millions of songbirds are vacuumed out of trees and killed during the olive harvests in the Mediterranean.
Most of these song birds are legally protected birds which seek refuge in the Mediterranean during the winter months. At night, they roost in the olive bushes and are sucked into the harvesting machines which strip the trees of their fruit.
Hannah Arendt famously discussed the banality of evil – how monstrous deeds may be 'sleepwalked' into. Folks can fall into immensely destructive patterns due to prevailing culture and incentives, and dreadful suffering loosed upon others soon becomes normalized as second-nature.
As long as we are not obliged to recognise and pay for costs that we needlessly pass on to others, we will continue to enable immense sentient suffering, and ecosystem destruction.
Pushing unpaid costs onto others, including the public and environmental commons, is a form of fraud, and must be prosecuted as such.
We pass on so many costs onto others, consciously or unconsciously that it's almost impossible to "be aware" of those costs.
The interaction amount, intensity, frequency etc. that we engage in with people on a daily basis is so large. If there's anything we could do, then it would be to find what hurts the most and start there, but following that trail in the longer term (for long term damage), becomes more difficult as the ripples get exponentially fuzzier.
