Solution:Many of our waste products end up in the sea and then can move through the ocean, endangering marine life through entanglement, ingestion and intoxication. Sources of marine pollution Common items of marine litter in the sea include cigarette butts, crisp/sweet packets, cotton bud sticks, bags and bottles.
Man-made items of debris are found in marine habitats throughout the world, from the poles to the equator, from shorelines and estuaries to remote areas of the high seas, and from the sea surface to the ocean floor.
About 80% of marine litter comes from land-based sources (eg. through drains, sewage outfalls, industrial outfalls, direct littering) while 20% comes from marine-based activities such as illegal dumping and shipping for transport, tourism and fishing. Plastics are estimated to represent between 60 and 80% of the total marine debris.
Manufactured in abundance since the mid-20th century, most of the plastics that have been produced are still present in the environment. The cumulative amount of plastic produced since the mid-20th century is of the order of 5 billion tons, enough to wrap the Earth in a layer of plastic rope. The amount projected by 2050, on current trends, is about 40 billion tons, which is enough to wrap 6 layers of plastic wrap around the planet.
The coral reefs in Southeast Asia are the most threatened in the world. About 95 percent are at risk from local threats (i.e., coastal development, overfishing/destructive fishing, marine-based pollution, and/or watershed-based pollution), with almost half in the high and very high threat categories Therefore, Statement I is false but Statement II is true
