Biocentrism What weaknesses in other motivations for conservation does biocentrism attempt to address? What is sentience?

Ecocentrism and the Evolutionary- Ecological Land Ethic Based on the idea that natural systems should be preserved as completely as possible simply out of respect for natural systems. A central belief is that the proper function of natural biological systems requires all components normally found there in the proper proportions. “to keep every cog and wheel is he first principle of intelligent tinkering”.
