Topic: Sustainability (Overfishing to be exact)
Introduction
Hello! Before I mention anything else, I’m gonna address the fact that you might be wondering: “Why overfishing? There’s plenty of fish in the ocean.” Well, there was. So what happened to the fish if there WERE plenty of fish? Here’s the simple answer: Population and technology happened.
There’s an ever increasing demand from an ever increasing population. Before we go any further, here’s an explanation about sustainability and how it can help prevent overfishing.
Explanation
Sustainability. Let’s say we have a fisherman fishing out of a pond of 36 fish (36 is the carrying capacity of the pond). The fisherman catches 18 fish every month, and by the next month, the fish have safely doubled back up to 36 fish. This is a sustainable cycle; as long as these fish can double back up to 36 fish every time, they can survive forever. However, one month the man takes 20 fish instead, leaving 16 in the pond. The next month the fish only double up to 32. After seeing the slight difference, the man decides to go back to fishing 18 each month since that was safe. When he fishes 18, the number of fish decreases to 14, then doubles to 28. 28 decreases to 10, and doubles to 20. 20 decreases to 2, doubles to 4, and now the man has barely any fish left in the pond, and would have to wait multiple months for the fish to reproduce all the way back up to 36.
This is how sustainability works. As long as there are enough to reproduce to the carrying capacity, they will survive forever. However in our world today, fish are not being caught at a safe sustainable rate. By now, you probably get the picture, so let’s take a look at what the main causes of overfishing are.
The Main Cause
There is one major cause of overfishing, and that is again, our ever increasing population, and the food market’s increasing demand for seafood. However, the main method of overfishing is “Bottom Trawling”. What this is: Boats cast huge, heavy nets that are opened by heavy doors (these doors weigh several tons) that drag the nets across the ocean floor. It not only catches LOTS of fish, but it damages any habitats that it happens to run over.
The Effects
Disclaimer: Not only is marine life being impacted by overfishing, but human lives are as well.
-Coral reefs (which house 25% of marine life) are being destroyed from overfishing.

-Loss of livelihood for fishermen, requiring them to move to a different profession or career.
-Imbalance in the ecosystem which also causes other habitats, and fish species to be destroyed.
-Reduction in marine biodiversity (number of species and population).
-Makes stressed ecosystems more vulnerable to invasive species, which could endanger said species.
-Since Industrial fishing began in the 1960’s, 90% of commercially targeted fish have disappeared.
-It’s exploiting other types of marine wildlife getting caught in the nets, such as dolphins, or other fish not needed for the market. These fish usually die while getting sorted out, and are known as bycatch.
-At this rate (which will likely only speed up), all seafood will be gone in 27 years. (You can see the countdown at https://www.theworldcounts.com/stories/facts-on-overfishing)
The list goes on and on… although mine doesn’t.
However, it’s not hopeless. There are things people are trying to do to prevent/mitigate overfishing, and you can check them out at https://greentumble.com/long-term-effects-of-overfishieng/.
Instead of telling you what OTHER people are doing, I’m gonna cut straight to the chase and explain what YOU can do to make a difference.
What You/The People Can Do to Help
(Another) Disclaimer: Seafood supplies protein to over a billion people in the world, so tackling this problem will take lots of combined efforts.
-The government is closely watching the fishing industry, and banning illegal fishing of endangered fish so they have time to replenish and restore numbers. You can do your share by watching what you eat and spreading the word about it.
-Look for the Dolphin Safe label instead of Dolphin Friendly. According to theworldcounts.com it was awarded by the Earth Island Institute who has the strictest system of monitoring.

-You can tweet or email your congressman about overfishing. Let your voice be heard, and you could start a revolution of change!
-Support industries/websites that protect the ocean. They have a big job ahead of them, and they need all the help from every person they can get.
-Don’t look at this list and say, “Ehh, someone else can do it”. YOU can make a difference. I encourage you to complete at least one of these things on this list.
Conclusion
I hope you learned something about the seriousness of overfishing. With over 90% of commercially targeted seafood gone, that makes more competition over less fish, which means that they’re numbers will only decrease from here… unless we do something about it.
(Also, I'd appreciate it if you left a comment telling me what you learned from this post and which of the challenges you're going to do. I'm looking forward to seeing what you all do!)
