Your argument is predicated on the fact that ‘they must be done’. I disagree.

Almost every meaningful human endeavor will result in some human deaths from time to time. A position of zero harm closely resembles a position of zero progress.

Could anyone down voting provide counter examples? I propose no one reading this could even produce the devices we're typing on without mining, handling and transporting hazardous materials, and using heavy equipment which will occasionally result in an unfortunate human death and or harm to the environment.
