That adds up to about 11,417 sharks per hour and 100,012,920 every year. Co-author of “Sharks of the World” Leonard Compagno said, “The dawn of the latest extinction crisis was less than 20 years ago” (Compagno page 43). This over-fishing is destroying the ocean ecosystem by taking a vital part
Global Warming Affecting Coral Reefs are worth $375 billion each year. They earn this money by attracting tourists. People also make a profit from the fish species that live in the coral (Casper 182), so if all the coral die due to global warming, humans will be affected as well. Coral are marine plants, and marine environments are the most diverse habitats in the world. If the planet was to lose all the coral in the world, it would decrease the diversity of the ocean (Casper 184).
Moreover, Myers and Worm (2005), confirmed a general decline in large predatory fish communities worldwide by at least 90% over the last 50 years - 100 years. Many of international organization are attempting to identify the species and
A research carried out by the Sea turtle conservancy showed that 100 million marine animals are killed every year due to plastic debris in the ocean around the world. This is a massive amount of innocent, marine animals to be killed every year, from as little as fish and sea horses, to massive whales. They are a non-profit organization who carries out missions in order to save turtles from extinction. Their studies are carried
Keeping the Ocean Free of Debris Pollution in the Persian gulf is negatively impacting marine life How much are we trashing our ocean? CNN, February 12th 2015. Arabian Gulf coral reefs dying a slow death. Gulf news, June 10th, 2014. Spill, Dolphin Deaths Spark Alarm At Persian Gulf Pollution.
1. 90-100 million tons are killed and wiped off the planet each year. Consisting of some of the most beautiful creatures on the planet. Fish are a primary food source to 3.5 billion people worldwide and the depletion of the species is leaving millions of people hungry. Over fishing is a huge problem that needs to be stopped.
It is no secret that humans have a large issue when it comes to plastic waste, as we produce over 300 million tons of plastic each year, with 50% used once and thrown away. But where does all of our plastic debris go once we discard of them in the trash? The answer, oftentimes, is the ocean. According to a UC Santa Barbara study, over 8 million tons of plastic is thrown into the ocean each year, and since 10% of our trash ends up in the ocean, 90% of which being plastic waste, it is estimated that 5 trillion pieces of plastic, weighing 250,000 tons, are floating in our oceans right now. However, when you visit your local beach, it is unlikely that you see mounds of trash washing ashore.
This is especially concerning, given that they form crucial microhabitats for many reef-dwelling species and are important components of fisheries. Startlingly, plastic waste was found on one third of the corals analysed, with around 2 to 10.9 plastic items on each 100 m2 section of coral reef. Perhaps even more startling is the extent to which ocean pollution that can be attributed to human carelessness in managing waste. It has previously been estimated that 80% of the plastic waste that litters our oceans initially came from land. The researchers further concluded that the levels of plastic found on coral reefs corresponds to the estimated levels of plastic waste deriving from land as a result of poor management
“At this rate, we would expect nearly one ton of plastic for every three tons of fish in our oceans by 2025,” says Nicholas Mallos, director of Ocean Conservancy marine debris program. Ocean pollution is a very evident problem. There are two types of pollution, nonpoint source pollution, and point source pollution. Nonpoint source pollution is pollution that is a result of runoff, which comes from smaller sources and point source pollution is pollution coming from a single source, such as an oil spill. Point source pollution has a larger impact on the ocean compared to nonpoint source pollution but thankfully it occurs less.
Their numbers are dwindling because they face many dangers, the biggest which is humans. Populations of sea turtles worldwide have dropped by 80% to 90% since 60s. Leatherback and Hawksbill species is listed as one of the 10 most endangered animals in the world. On the other hand, the green turtle hatchlings. Even the scientists have estimate that only one of each thousand hatchings will survive till
