Dugongs are completely dependent on seagrass meadows for food, making habitat loss from pollution and development a direct welfare threat to these gentle marine mammals.
Dugongs dependent on degraded seagrass habitats face chronic nutritional stress as they must travel further to find adequate forage, expending more energy than they can easily replace. Pregnant and nursing females are particularly vulnerable to nutritional stress, which reduces calf survival. Dugongs entangled in fishing gear experience drowning and panic as air-breathing mammals unable to surface. The slow reproductive rate means population impacts from individual welfare harms take decades to manifest, making prevention far more important than population response.
