I need serious scientific on reducing harm,within my own lifesyle,to other living organisms and sentient beings.
For example; eating cereal,which is a crop. are pesticides and anti-insect products used in cultivating cereal?if yes,i wont eat cereal. Just fruits! so on
for example:
>are sperm sentient?do wet dreams release sperm?(justification for trying to not-sleep)
>what are the main causes of harming the eco-system and animals and plant life?
>should I pluck out,not cut,my hair to avoid harming lice and vermin?
