Sydney Harbor, located within Port Jackson in Sydney, Australia is a wondrous scene that is notorious for its splendor. This inlet of the Pacific Ocean is over twenty square miles and more than ten miles long. It is considered to be one of the world's most excellent natural harbors. Sydney Harbor is even home to numerous naval and military locations, as well as the illustrious Sydney Opera House. As much as Sydney Harbor is such a beautiful site, below the glistening blue waters of the bays they are full of dying and decaying sea life.

All around the world, due to watercrafts, storm water runoffs, and industrial waters, metals like copper, zinc, and lead mix into rivers, seas, and oceans. As for the Pacific Ocean itself, has been the victim of nuclear waste dump, oil spills, plastic, glass, and many other hazardous materials. Throughout my research, many scientists and their crew members have claimed to have fished out large debris, such as; tires, steel rims, cathode ray tubes, bleach bottles, and abandoned fishing nets and hawsers.

We all know that substances such as those mentioned can't be good for the waters, but just how bad is it?

In one word; bad. Scientists have estimated that on average, there are over six thousand animals per square meter in the Sydney Harbor. The Pacific Ocean's greatest asset is the shellfish, tuna, swordfish, salmon, sardines, herring, snapper, and thousands upon thousands of small shrimp like creatures called amphipods and crustaceans that feed upon the seaweed out of Sydney Harbor.

This common brown seaweed has been considered the most contaminated in the entire world because of the high levels of copper, lead, and zinc. The brown seaweed absorbs the copper, lead, and zinc which inevitably enter the marine life that use that seaweed as its food source. Sited by www.firstscience.com, the UNSW laboratory and field experiments state that up to 75% of the crustaceans as well as their offspring parish from consuming and being exposed to such dangerous levels of copper, lead, and zinc.

Takeaways
  • Due to industrial waste contamination of high concentrations of zinc, copper, lead go into waters.
  • Up to 75% of the crustaceans as well as their offspring parish from consuming those heavy metals.
  • Copper is released into the environment it automatically attaches to organic matters and soil.
