In the article “ China’s appetite pushes fisheries to the brink” it talks about fisheries and how they are affecting the oceans”. Decades ago, the oceans were crawling with billions  of sea creatures, there was an abundance of everything, it was a fisherman's dream. But these days, fishermen's nets are coming up empty. Overfishing has caused many fisheries to collapse and fully exploit their resources. China, with over 1 billion inhabitants, is a major market place for seafood.

In the news article, “Heat waves are roasting reefs, but some corals may be resilient”, it touches the subject of an important ecosystem change. Over the span of a couple years, many coral reefs are being destroyed due to the change in water temperature. For example, there was a heat wave back in 2016 that killed 30 percent of coral in the great barrier reef, a home to many creatures and a must for keeping the ecosystem in tact.

In the article “Fisheries impacts on China's coastal ecosystems: Unmasking a pervasive ‘fishing down’ effect” by Cui Liang and Daniel Pauly, the authors explain how the intensive fishing can greatly impact the marine ecosystems and a lot of other aspects. This indicates that the trophic level of the catches to decrease, and it’s a signal of the existence of the ‘fishing down’ (FD) occurrence.

The connection between shrimp and climate change

The article entitled, "Our growing taste for shrimp is bad news for climate change" by the author Erik Stokstad is about the fact that the demand of seafood is increasing just like the level of carbon dioxide emitted in the atmosphere and the oceans. Crustaceans, shrimp and lobsters are in constant demand for seafood restaurants, grocery stores and markets. The economy is doing well for this part, but it is not the same situation for the aquatic species and for the health of our planet.

According to the article “Even small changes within an ecosystem can have detrimental effects”, the relationships between all species may lead to the collapse of the entire ecosystem, if there is a poor connection. One of the research was based on Acacia tree from East Africa Savanna and the interaction with ants that inhabit them.

Shark overfishing

Submitted by Beatrice Manning on April 29, 2018 - 1:00pm

In the article “Sharks at risk of extinction from overfishing, say scientists.” I realized that over fishing was a big issue to many species. In Asia, sharks are fish for their fins to make a shark fin soup. When they fish the sharks, they cut their fins and they put the rest of the dead shark back in the water. The problem is that more than 100 millions of sharks are fished each years and sharks take a lot of time to reproduce and they take time to be full developed. Because of overfishing we became their #1 predators.

Australia's affect on the local ecosysten

Asutralia has one of the world largest reserve marine zones in the world (Which means they are not allowed to be used for fishing at all) This will have a huge impact on the species as these environment have never faced such high levels of human activity. The reason for opening up all of this new fishing area is in an attempt to help local fishing economies and help employment. But doing this is threating a whole bunch of marine life that we haven’t even seen or documented. But the scirenticfic community and environmentalist are fighting to save these zones.

In the article "Fishing problems: poor fisheries management," it explains the problems that are going on in oceans and fisheries and what their main causes and affects are. Oceans are also threatened by marine plastic pollution and each year, an estimated 8 million tons of plastic enter the oceans, with microplastics becoming part of the food chain. Scientists estimate that without urgent action, there could be more plastic than fish in the ocean by 2050.  While complex, the issue of ocean plastic waste is a solvable challenge.
