Social Science- Future of Fishing

Hello, this is my blog post on sustainable fishing and I need to answer two questions: Is sustainable fishing even possible and how is commercial fishing a threat to dolphins and birdlife (bycatch)?

I believe sustainable fishing is either going to be very difficult or impossible, this is because of how many people are in the world and how difficult it would be to make people fish smarter and to stop overfishing. We overfish 50% of the fish caught.

Sadly every 8 tunas, 45 dolphins are caught by bycatch and this ridiculous, bycatch is causing one death every 2 minutes and with over 300,000 dolphins and small whales being killed by fishing nets and other fishing equipment. Longline and trawl fisheries kill over 300,000 seabirds each year. These accidental deaths, known as bycatch, are the result of birds becoming caught in fishing gear.

While Japan is fishing up tens of thousands of dolphins this is going to cause the population of dolphins to drop down a lot, possibly making dolphins go extinct. And that doesn't even include bycatch, they kill 20 thousand a year on purpose and worldwide fishing operations are catching about 80,000 dolphins every year per 1,000 tonnes of tuna and it's estimated that 174 dolphins on average per that 1,000 tonnes are getting trapped in nets.

Nail Rusting Science Experiment

Nail Rusting Science Experiment

We had to investigate a number of ways that may prevent rusting.

The Tap water did nothing

The Saltwater rusted the nail pretty good
The Nail with boiled water and oil rusted a little bit
The Calcium chloride Nail with a bung did nothing
The Nail with zinc and magnesium did next to nothing
The Painted nail was pretty rusted
The Vaseline nail did nothing

My conclusion is that the results are basically what I was expecting, and I don't think the nail with paint was sealed properly. The saltwater nail had the most rust on it and the Calcium chloride nail barely rusted, because Calcium chloride removes moisture and moisture and oxygen is needed to rust.

Social Science- Shark Finning

Shark finning is a fishing industry that collects shark and skin the fins off the sharks, sometimes they would catch and fin them alive and throw them out to let them slowly die. Sharkfin soup is a delicacy in China that dates back to AD 968, it was created by an emperor and it was created as a sign of the emperors status and wealth.

Finning sharks disrupts the food chain, as the apex predator of the ocean, if sharks went extinct then the next stage of the food chain will be overpopulated and will go extinct and will continue to repeat until there are no more fish left in the ocean.

Social Science- Deeper meaning

Once upon a time there was a wise man 
who used to go to the ocean 
to do his writing. 
He had a habit of walking 
on the beach 
before he began his work. 
One day he was walking along 
the shore. 
As he looked down the beach, 
he saw a human 
figure moving like a dancer. 
He smiled to himself to think 
of someone who would 
dance to the day. 
So he began to walk faster 
to catch up. 
As he got closer, he saw 
that it was a young man 
and the young man wasn't dancing, 
but instead he was reaching 
down to the shore, 
picking up something 
and very gently throwing it 
into the ocean. 
As he got closer he called out, 
"Good morning! What are you doing?" 
The young man paused, 
looked up and replied, 
"Throwing starfish in the ocean." 
"I guess I should have asked, 
why are you throwing starfish in the ocean?" 
"The sun is up and the tide is going out. 
And if I don't throw them in they'll die." 
"But, young man, don't you realize that 
there are miles and miles of beach 
and starfish all along it. 
You can't possibly make a difference!" 
The young man listened politely. 
Then bent down, picked up another starfish 
and threw it into the sea, 
past the breaking waves and said- 
"It made a difference for that one."

-What is the meaning of this poem
-Show evidence
-Add an image

The message of this poem is to show that one small good thing can make a big difference. A small thing like chucking the starfish back into the ocean is a huge thing for the starfish, it would've dried up in the sun but its life was spared. 

GPGP Newspaper

Shockingly The Great Pacific Garbage Patch is an environmental catastrophe caused because of poor waste mismanagement by civilization, and it was discovered in 1997 by a yachtsman by the name of Charles Moore. 

Why should we care about the Great Pacific Garbage Patch? The Great Pacific Garbage Patch, and plastic pollution generally, is killing marine life. 1 million seabirds and 100,000 marine mammals are affected every year, as well as many other species around the world because of the food chain. Eventually plastic will heavily affect our food supply making it difficult for food surplus to get out into the public eventually.

The GPGP is the largest island of trash is located near Japan, it contains 1.15 to 2.41 million tonnes of plastic, 1.8 trillion pieces of plastic, 652+ surface nets and the GPGP is three times the size of France.

Corrosion Blogpost

Aim: To find a number of methods that can prevent rust and finding out factors that cause rust in metal

Equipment: 8 Test tubes, test tube rack, a bung, tap water, vaseline gel, nail polish or paint, zinc pellets or magnesium ribbon, boiled water, salty water, cooking oil, calcium chloride.

Method: Label 8 test tubes A-H

Fill all test tubes with equal volumes of water, enough to cover the nails

Nail + Tap Water

Nail + Vaseline + water

Nail + Water + Nail polish/paint

Nail + Water + Magnesium ribbon wrapped around it, or zinc pellet added to the test tube

Nail + Salty Water 

Nail + Boiled Water + Oil

Nail + Calcium Chloride sealed with a bung (NO WATER)
