Plastic dumped into the oceans disrupts and kills marine life, and has for a long time. As long as I've been alive. Some marine species get caught up in the flotsam and ingest others. I've seen this many times as a fisherman. Plankton itself is affected by the breaking down of the plastics. I've seen and heard this since high school, and this AI explains more........... Entanglement and Physical Injury Larger plastic debris—such as derelict fishing nets, packaging, and discarded straps—create lethal traps for marine mammals, sea turtles, and seabirds. Entanglement restricts movement, making it difficult for animals to hunt, evade predators, or surface for air. [1, 2, 3, 4, 5] 2. Ingestion and Starvation Marine animals frequently mistake plastic for prey. For example, sea turtles often confuse floating plastic bags for jellyfish. When animals ingest plastic, it fills their stomachs, creating a false sense of fullness that leads to starvation. [1, 2, 3, 4] 3. Toxic Chemical Accumulation Plastic isn't just physically hazardous; it is chemically dangerous. Plastics contain harmful manufacturing additives and act as "sponges," absorbing toxic pollutants from the surrounding seawater. When ingested, these chemicals leach into the animal’s body, causing reproductive issues, developmental delays, and compromised immune systems. 4. Microplastics and the Food Chain Over time, sunlight and wave action shatter plastics into tiny fragments known as microplastics. These particles are consumed by microscopic zooplankton, placing the toxic synthetic material at the very base of the marine food web. As larger predators consume these smaller organisms, the plastic and accumulated toxins travel up the chain to apex predators and ultimately to humans. 5. Disruption of the Carbon Cycle Plastics interfere with the ocean's ability to regulate the global climate. When zooplankton eat microplastics, their waste becomes buoyant, causing carbon to release higher in the water column rather than sinking to the deep ocean floor. Furthermore, plastic exposed to sunlight releases greenhouse gases like methane and ethane into the water. These wildfires are happening all over because of the heat increasing, and building too many homes into the once forested areas, without making more reservoirs, is asking for a disaster to happen, as many have already, especially in California and Texas.
