(Wit’s End) – My last post here at Wit’s End received some thoughtful queries which deserved an answer in kind, a response I have assiduously procrastinated making - an avoidance which was made easier by a ten day trip with minimal access to the internet. Most of the photos in this post are from my journey to the UK earlier this month.
What follows is my belated reply (with apologies), especially to Michael Jensen’s question, “How has your personal mission changed, as the likelihood of your minimal long-term impact on the trajectory of global collapse has become clear?”
Most often, writing on a blog feels to have no more effect than idly dropping a pebble in the ocean, and watching the tiny ripples disappear; lately it seems that climate heating has gone exponential, and in my imagination I anticipate the moment I will hear an official NASA announcement on the radio - that it’s too late to mitigate climate change because irreversible amplifying feedbacks have taken over and there’s nothing left but to listen to the orchestra play on the deck.
For years, once I realized humans have despoiled the glorious biodiversity it took millions of years of evolution to achieve, I grieved. I was angry and horrified and mostly wracked with guilt about being oblivious of my own contribution to the Endocene, including having children. I wanted to know how and why our species is so destructive, and I needed to understand why most people persist in believing humanity is ecologically sustainable when we so patently are not. So I read a lot about history, archaeology, psychology, evolution, and biology.
I came to understand that human behavior is as immutable as the leopards’ spots, and that humans are fundamentally an invasive species.“Humans are just like any other invasive species,” Stanford University biology professor Elizabeth Hadly said. “If we use up our resources, we will decline. It is stating the obvious, but our study shows that even over vast geographic areas such as continents, humans can consume too much, too fast.”
Our species first appeared in Africa about 200,000 years ago, then spread to Europe and Asia and eventually crossed into the Americas roughly 15,000 to 20,000 years ago using a land bridge that once connected Siberia and Alaska.
The first phase of colonization in South America coincided with the extinction of many large animals including elephant relatives, saber-toothed cats, big ground sloths, armadillos, and huge flightless birds. [more]
