It’s generally acknowledged that we are now officially in the midst of a major phase of extinction when it comes to plant and animal life on our home planet. Whether it’s called the Sixth, the Holocene or the Anthropocene Extinction, this wave of die-offs is the biggest in almost 70 million years, when three-quarters of all plant, animal and sea life perished in the Cretaceous-Tertiary Extinction.
There are a couple of key differences between these two major extinction events.
For one thing, the earlier extinction is widely considered to be the result of a massive asteroid impact that had a series of long-lasting effects – but there is some disagreement on that origination story. Other causes could have been a series of volcanic eruptions, or climate change, or sea level change. At this great distance, we don’t know if it was one factor or a combination of factors. In any case, it was a planetary change caused by elements far beyond the control of the species that went extinct as well as those that survived.
This time around, we have a fairly clear idea of what is causing the current round of extinction, which is proceeding at a rate estimated at 140,000 species per year. That’s every year, not a cumulative number. Species are dying off at far higher rates than we can count them.
This time, we know that what’s causing this epic die-off is a combination of climate change, habitat loss, human impact in the form of hunting, industry and pollution.
Contrary to the last time around, this is no outside force: This time, a single species is having the impact of a major asteroid. Or a series of volcanic eruptions.
On a positive note, in the midst of all this, there is hope. As it turns out, when we put our collective mind to a task, we can turn the tide. New Chinese regulations banning the ivory trade, a crackdown on trafficking in pangolin products and a classification by the IUCN of the animals as extremely threatened, might well end up saving these animals from oblivion.
It’s the efforts of people on the ground, like the Pangolin Men and the Tikki Hywood Trust shown in these images by Adrian Steirn, that make the crucial difference. Coalitions of farmers and activists, municipal and state bans on the use of known insecticides or the promotion of green havens, big regulations combined with hands-on local work and dedication, it all counts.
We won’t save everything, but we can slow the rate considerably. Individual efforts can make a real difference.
