environmental ethics | study and practice of human actions that impact the environment and contribute to the well being of humans, societies, and the natural world |
three ethical foundations | intrinsic value, instrumental value, and value of environmental stability |
moral principles | the rules we ought to follow |
moral goals | the aims that we are worthy to achieve |
first action | change personal habitats that degrade the environment |
overview effect | typically with astronauts, the awe of seeing creation at one time |
six of moral principles | care for creation, human dignity and rights, common good, universal destination of goods, preferential option for the poor, subsidiarity |
seven moral goals | protect and preserve biological diversity, respect natural resources, support sustainable and renewable energy, conserve and protect water, make healthy food and sustainable food, encourage authentic and integral development |
five actions | change personal habits that degrade the environment, discover, research, and respond to local problems, participate in already existing local efforts, research and support public policies, and participate in social movements |
five environmental challenges | declining biodiversity, natural resource extraction, transition to renewable energy sources, water quality and quantity, industrial food system, global climate change |
pantheism | the universe is a manifestation of God |
paganism | the divine is within nature |
theism | the divine is beyond nature |
Christian environmental stewardship | We can not love God while destroying His creation |
cultural mandate | be fruitful and multiply and have dominion over living creatures |
