A renewable-energy transmission line may cross already disturbed habitat when it is necessary to provide reliable low-carbon power to large populations. In other words, the project could use land that is already damaged if that route is genuinely needed to deliver reliable low-carbon electricity.

Predators that repeatedly kill livestock may be lethally controlled when nonlethal measures have failed. In other words, nonlethal measures can include fencing, guard animals, relocation, and compensation.

Housing may be built on degraded habitat if independent review confirms that developers will restore genuinely comparable habitat elsewhere and prevent a net increase in pollution. In other words, development would be allowed only if outside reviewers confirm that equivalent habitat will actually be restored and overall pollution will not increase.

Coastal flood defenses for dense communities should take priority over preserving every natural shoreline in its existing form. In other words, flood defenses can include seawalls, barriers, elevation, dunes, wetlands, and managed retreat.

Farming practices that cause severe, avoidable animal suffering should be phased out even if meat becomes more expensive. In other words, animal-welfare regulation can address confinement, handling, transport, and slaughter practices.

Mining should be denied in an intact watershed whose ecological functions cannot realistically be replaced. In other words, mining would be refused where the connected river, groundwater, and habitat system cannot realistically be recreated elsewhere.

Governments should restore wetlands and floodplains even when doing so removes some land from future development. In other words, wetlands and floodplains can reduce floods, filter water, and support habitat.

Government may prohibit private development in a critical wildlife corridor even when owners are willing to accept environmental mitigation. In other words, a wildlife corridor connects habitats needed for migration, breeding, and genetic diversity.

Large desalination plants should be built to secure water for cities even when they cause manageable but significant harm to marine ecosystems. In other words, desalination removes salt from water and can affect marine life through intake systems, energy use, and concentrated brine discharge.

Precision fermentation and cultivated meat should be deployed to reduce land use and animal suffering even if they disrupt conventional agriculture. In other words, new food technologies would replace some conventional livestock farming, reducing land use and animal suffering while disrupting existing farmers and industries.

Environmental law should permit essential human development to override habitat protection when several legitimate values conflict and no single value has absolute priority. In other words, the scenario treats ecological protection as one important value among several rather than an absolute side constraint.

Government may approve a major fossil-fuel project when it is the most practical way to provide affordable and reliable energy, even if it causes substantial ecological and climate harm. In other words, urgent human energy needs can outweigh serious environmental damage when cleaner alternatives are not yet practical at the required scale.

Highly sentient animals should have legal rights that can block profitable human uses causing severe suffering. In other words, some animals should be treated as holders of enforceable interests rather than only as property whose welfare humans may choose to protect.
