Which concept emphasizes humanity's duty toward the environment as expressed in Christian faith?

The concept that highlights humanity's duty toward the environment within Christian faith is stewardship of creation. This principle underscores the belief that humans are entrusted with the care and management of the Earth and its resources. Stewardship is based on the understanding that creation is a divine gift that should be nurtured and respected, reflecting a commitment to sustainability and responsibility.

In many religious teachings, including Christianity, stewardship involves using natural resources wisely and responsibly, ensuring that the environment is preserved not only for current generations but also for future ones. This connection fosters a sense of obligation to protect and care for the planet, which is seen as an integral part of one's faith and moral duty.

The other options, while related to environmental attitudes, do not convey this principle of active responsibility and care. Denying responsibility implies a neglect of duty, promoting unchecked industrial expansion contradicts the ethos of conservation, and isolation from ecological principles suggests a separation that does not align with the interconnectedness taught in many faiths, including Christianity. Thus, stewardship of creation stands out as the correct answer as it embodies the proactive and respectful relationship towards the environment that is encouraged in Christian doctrine.
