The protected areas in marine life actually have a wide range of social, cultural, ecological and economic benefits, which I have talked about in this guide. The extent to which these benefits can be achieved are largely and completely dependent on design, location and management as well.
A very well designed marine protected area can help in promoting very healthy ecosystems which are completely resilient and are also able to adapt to stress. It is so because they are complex systems which are inbuilt with buffers. The resilience has been known to enable marine life community to which stand some pressures while also retaining their basic function. This includes the delivery of the ecosystem services which we all rely upon. There are some critical services which include climate regulation, nutrient recycling, oxygen production and also the production of protein for human consumption.
The proper complexity of marine ecological dynamics is actually making it so hard for scientists to properly assess the impact of human-related activities on the marine environment. Well, I can say with absolute certainty that human activities have negatively impacted the marine life because, thousands of species have gone extinct and even more have gotten endangered, because of said human activities. The coral reefs are actually getting significantly impacted, and a lot of them are dying out, because of human activities. There is so much plastic in the ocean, and this plastic starts affecting the marine life. Because marine reserves exclude fishing, they can actually provide proper and useful information on all of the characteristics of a population that has not been exposed to fishing. This can then be compared with those of the population that has been subjected to fishing. This will also improve an indication of any extent which is cost by fishing. We can then inform the fisheries to make certain decisions.
The areas that are protected by individuals actually benefit commercial and recreational fissures because it contributes to fishing stock. It basically means, the areas that are protected have proper numbers of fish that can actually be useful for fishing. Marine protected areas give nature time to heal from human activities. Marine reserves actually support the denser population of larger fish and even resident species which are also heavily fished.
There was a recent study of some marine reserves, and it was found that they were 13 times larger and also more than the legal size limit. This actually has some very important implications when it comes to reproduction. Large fish can actually produce way more eggs than smaller fish. We need to consider these things, as well. There is some evidence that suggests that the larvae which are produced by larger fish have way better survival rates.
Human beings are incredibly lucky because they have a planet that is made up of 71% of water. Water happens to be one of the most important resources of food and many other things. Water has always been a resource, and we need to appreciate it more. There are more than three .5 billion individuals who are immensely dependent on the ocean as their only and primary source of food. There are a lot of people in the world who depend on fishing to eat every single day. This is why the numbers of fish are rapidly diminishing every single day. The habitats of many creatures are being threatened by overfishing. In this guide, I will be talking about some pros and cons of overfishing.
The dumping of plastic in the ocean has become a significant threat. For example, there is a plastic Island, the size of Texas in the ocean. It is catastrophic, indeed. It goes into the systems of many marine creatures and kills them, and we need to stop this. Almost 100,000,000 sharks are killed for their meat and orphans, and it is actually illegal to do so, but people still do it anyway. Twenty million tonnes of marine life is destroyed for humanity’s greed. It is honestly pathetic, what we are doing to the ocean, something that is incredibly important to us.
- Fishing has actually created a lot of job opportunities for millions of individuals. Since aquaculture became a huge thing, a lot of jobs have been made available to so many individuals. These jobs have been able to fund the lives of a lot of people.
- It provides a whole new set of skills.
- It also helps in boosting the economy, and it helps people eat healthier. Seafood is considered very healthy, when compared to other meats.
- Sometimes, fishing can help replenish the marine life, when there are some overpopulation problems in the sea or ocean.
- It certainly causes a huge dent in the marine life population. It is true for a large number of species out that. It also has caused the extinction of thousands of species in the oceans. Fishermen do not know which species of fish are endangered; they grab whatever they can get in the net and take it to their village to eat or sell.
- It can actually cause overpopulation of other species. When sharks were over fist, it resulted in the overcrowding of jellyfish and this, in turn, made the water very unsafe for humans to swim in.
- Overfishing has been known to increase pollution, and it makes it very unsafe.
It also causes a total collapse of fish stock. When too much commercial fishing is made, some seas are uninhabitable to many kinds of marine life.
