Name three problems fish develop after eating plastic.

1. Physical damage or obstruction of digestive tract: When fish eat plastic, it can cause physical damage to their digestive tract, leading to infections, internal bleeding, and even death.

2. Poisoning or chemical contamination: Plastic can contain harmful chemicals like bisphenol-A (BPA), which can leach into the fish's body and cause hormonal imbalances, reproductive problems, and damage to vital organs.

3. Blockage of gills: Fish may accidentally ingest plastic while filtering the water they breathe in through their gills. This can lead to blockage of the gills, making it difficult for the fish to breathe, and ultimately causing suffocation and death.
