The three main environmental ethical philosophies are: anthropocentrism, biocentrism, and ecocentrism, all of which are our key terms for today. Ethics are basically moral principles; therefore, environmental ethics are the moral principles about the relationship between humans and the environment.
First is anthropocentrism, which means to be concerned with actions to improve the state of the environment for the well-being of humans.
Next is biocentrism, which means to be concerned with actions to improve the state of the environment for the well-being of all living things.
The third and last environmental perspective is ecocentrism, which means to be concerned with actions to improve the state of the environment for the environment itself, which includes humans.
IN CONTEXT
Let's look at a single environmental issue from each of the three angles: deforestation.
Anthropocentrists would view deforestation as valuable if done at a rate that enables future humans use of tree resources.
Biocentrists would view deforestation as harmful, because it is damaging living beings.
Ecocentrists would view deforestation depending on its global ecosystem impacts, which would most likely be in a negative light.
Environmental stewardship is when humans take action to protect the environment based on their ethical beliefs. Anthropocentrists, biocentrists, and ecocentrists can all be environmental stewards, though the actions they might choose to take could look very different.
EXAMPLE
Conservation of resources, recycling, and land restoration are all stewardship actions.Environmental stewardship is essentially environmentalism in action. Again, environmentalism is not determined by scientific objectivity, like environmental science, but is a subjective interpretation of good or bad actions that humans should make in relation to the environment.
IN CONTEXT
Let's look at a more specific example of environmental stewardship: wastewater management. The photo below shows what is called a living machine. Living machines were invented to clean human wastewater by moving the dirty water through various tanks to mimic how a natural wetland cleans water. The goal is to clean water without harmful chemicals. Living machines use microbial life, plants, and fish to clean and test water before it is returned to the surrounding natural ecosystem. This is a form of environmental stewardship.
