Questions & Answers

Q: What is the North Pacific Gyre?

The North Pacific Gyre is a massive system of ocean currents that acts as a vortex, collecting trash and forming a large ecosystem in the North Pacific.

Q: How much trash is present in the North Pacific Gyre?

There is estimated to be at least 100 million tons of trash in the gyre, and this number continues to increase due to the non-biodegradable nature of the plastics.

Q: How does trash end up in the gyre?

Around 80% of the trash in the gyre comes from land, carried by powerful ocean currents. The remaining 20% comes from offshore oil rigs, commercial fishing, and cargo ships.

Q: What are the consequences of the North Pacific Gyre's trash on marine life?

Marine life faces numerous challenges, including entanglement in fishing nets, ingestion of plastics, and exposure to harmful chemicals leached from the trash, disrupting the food chain and causing detrimental effects.

Summary & Key Takeaways

• The North Pacific Gyre is a large system of ocean currents that collects trash and forms one of the world's largest ecosystems.

• The gyre is not a floating island of trash but consists of two huge areas with high concentrations of suspended garbage.

• The trash in the gyre is primarily composed of non-biodegradable plastics that photodegrade into microscopic particles, polluting the water and harming marine life.
