Fish is really good for you… isn’t it?

Fish is good for you…isn’t it?

Well, yes and no. There are definitely good elements to fish to help you with your diet, including protein, omega-3 fatty acids etc.  However, I’m afraid to say this is counteracted out with the abuse the ocean receives from pollution.

 

Due to pollution occurring, our fish are becoming toxic.  As a result, it is even strongly suggested that pregnant women should not eat any fish during their pregnancy. That’s pretty serious!

 

 

Why are fish so toxic?

According to science alert, the oceans are becoming polluted with micro-beads (which tend to be found in different types of cosmetics including face scrubs and toothpaste) and approximately 8 trillion of these beads are entering US waters every day.  As a result, the fishes absorb the polluted microbeads, which puts the person eating that fish at risk of consuming the pollution too.

 

Why are these microbeads causing such havoc?

So as we are scrubbing our faces with our favourite scrub and brushing our teeth with our minty toothpaste, the microbeads found in the products we use get washed away down the sink, and all drains lead to the ocean. This is where the beads come into contact with fish, which is inevitable as the beads are so small. This tiny form of plastic makes itself comfy in the stomach of the fish, where it attracts and concentrates toxic chemicals including pollutants which can cause neurological problems, decreased immune function, and even fertility problems. No one wants that for their fish supper on a Friday.

 

How can this be stopped?

Basically, ban microbeads from being used in such products. This is something which is being considered by the USA and Australian government within the next couple of years. Yay! As a society, we could try and use more natural products which do not include the micro-beads, every little helps.

 

Are there any safe fish to eat?

That’s a bit of a toughy, but here is a little list of what fish to avoid…fish and chip lovers….sorry;

 

  1. Blue Fish
  2. Chilean Sea Bass
  3. Pacific Ocean Perch
  4. Imported Catfish (Swai and Basa from Vietnam)
  5. Atlantic Cod (opt for Pacific cod)
  6. American Eel
  7. Atlantic Flatfish
  8. Caviar
  9. Shark
  10. Swordfish
  11. King Mackerel
  12. Tilefish
  13. Albacore Tuna (any tinned tuna) or Tuna Steaks
  14. Spanish Mackerel
  15. Orange Roughy

 

 

Acidification

Shall we look at some figures?

According to Ocean Portal, since the 1700’s/1800’s when the industrial era sparked up, the ocean has absorbed 525 billion tons of CO2 from the atmosphere.  Today the figures stand at 22 million tons per day.  With no sign of things getting better either; in the past 200 years the ocean has become 30% more acidic, and this change in this timescale is the fastest known in the last 50 million years…are we really that into our beauty products? Wow.

 

The visual effects

In a lab experiment, a sea butterfly (pteropod) shell placed in seawater with increased acidity slowly dissolves over 45 days.
