Deadly ocean trash - The impact of ghost nets
Every year, about a million tons of fishing nets are lost or dumped in the sea, known as "ghost nets," causing indiscriminate deaths of marine animals. Synthetic nets, which take up to 600 years to decompose, are a significant part of this problem. Initiatives worldwide attempt to salvage and recycle ghost nets, but the process is expensive and dangerous.
