I was listening to the noise of the big city, the rumble of traffic on the road, the sky encompassing roar of jet airliners above -- and realized I was listening to the sounds of burning oil. Burning oil that is causing catastrophic climate alterations and extinctions. The noisy process was impinging on my eardrums. Directly into my body and into my mind, making my soul squirm.
In a big city -- even in rural areas far from big cities -- the noise of industrial civilization is a constant background din. Something 'normal' people are simply supposed to ignore. Normal people are supposed to have more important things to think about and focus on and do. Like making money or spending it. Noticing these noises at all makes a person arguably weird. Obsessing over these sounds, and their meanings, is probably considered a form of madness by modern psychiatry.
We are supposed to ignore the destruction of our home. We are supposed to ignore the commonplace disrespect shown towards living things. We are supposed to deafen ourselves to the rumble... to the never ceasing buzz of our own demise. Or go mad.
