Entanglement in fishing gear, plastic waste, and agricultural materials causes acute suffering and death for hundreds of thousands of animals annually.
Entanglement causes acute suffering through drowning, strangulation, lacerating wounds, and exhaustion from extended struggle. For air-breathing marine mammals, net entanglement causes a prolonged drowning death lasting minutes. Ghost fishing gear continues to catch and kill for years after abandonment. Terrestrial entanglement in agricultural netting or fishing line can trap animals for days before they die or are found. The common thread is human debris left in wildlife habitats. Removing it — and reducing generation at source — is the primary welfare intervention.
