- The amount of plastic produced from 2000 - 2010 exceeds the amount produced during the entire last century.
- Plastic is the most common type of marine litter worldwide.
- An estimated 100,000 marine mammals and up to 1 million sea birds die every year after ingesting or being tangled in plastic marine litter.  
- 50 to 80 percent of dead sea turtles have ingested plastic. Plastic bags, which resemble jellyfish, are the most commonly found item in sea turtles’ stomachs.
- Worldwide, 82 of 144 examined bird species contained plastic debris in their stomachs; and in some cases, 80 percent of the population had consumed plastic. Researchers found that 66 percent of Giant Petrel shorebirds regurgitated plastic when feeding their chicks.
- Commercial fish, such as Opah and Bigeye Tuna, consume plastic, which could significantly reduce global populations. A University of Hawaii study reports “[i]n the two [Opah] species found in Hawaiian waters, 58 percent of the small-‐eye opah and 43 percent of the big-‐eye opah had ingested some kind of debris.”
- Impacts of marine debris have been reported for 663 species. Over half of these reports documented entanglement in and ingestion of marine debris. Over 80 % of the impacts were associated with plastic debris. 
- Up to 80% of the plastic in our oceans comes from land-based sources.  
- Plastics comprise up to 90% of floating marine debris.
- In 2010 about 690,000 tons of waste HDPE plastic "bags, sacks and wraps" were generated in the United States, but only 4.3% of this total was recycled.
- Plastics do not biodegrade, but instead break down into small particles that persist in the ocean, absorb toxins, and enter our food chain through fish, sea birds and other marine life.
- Plastic bags are problematic in the litter stream because they float easily in the air and water, traveling long distances and never fully breaking down in water.
- Cleanup of plastic bags is costly. California spends an estimated $25 million annually to landfill discarded plastic bags, and public agencies spend more than $500 million annually in litter cleanup. 
- It is estimated that Americans go through about 100 billion plastic bags a year, or 360 bags per year for every man, woman and child in the country.
- Those 100 billion plastic bags, if tied together, would reach around the Earth’s equator 773 times!
- Recent studies estimate that fish off the West Coast ingest over 12,000 tons of plastic a year. 
- Plastic debris in the area popularly known as the "Great Pacific Garbage Patch" has increased by 100 times in the past 40 years. The five oceanic gyres are estimated to contain 100 million tons of marine litter  and an estimated 20 million tons of plastic litter enter the ocean each year.
- At least 5.25 trillion plastic particles weighing 268,940 tons are currently floating at sea.
