Shark Allies Says Half A Million Sharks May Have To Be Killed To Make A COVID-19 Vaccine

Squalene, natural oil that is being harvested from sharks is being used in the Covid-19 vaccine. This ingredient is used as an adjuvant in medicine which increases the effectiveness of a vaccine by increasing the immune response.

In order to immunize everyone in the world with two doses of the COVID-19 vaccine containing squalene, would require around half a million sharks, a shark group said.

Around 3,000 sharks are needed to extract one tonne of squalene.

According to the Shark Allies, species targeted for being rich in squalene include the gulper shark and the basking shark, which are classed as vulnerable, meaning that their populations are decreasing and they could become endangered if the circumstances threatening them continue.

The advocacy group has said that harvesting an endangered specie for a component in the medicine is not sustainable.

“Harvesting something from a wild animal is never going to be sustainable, especially if it's a top predator that doesn't reproduce in huge numbers. There are so many unknowns of how big and how long this pandemic might go on, and then how many versions of it we have to go through, that if we continue using sharks, the numbers of sharks taken for this product could be really high, year after year after year," Stefanie Brendl, founder and executive director of Shark Allies told a US-based news website.

To avoid threatening shark populations, scientists are testing an alternative to squalene - a synthetic version made from fermented sugar cane.

According to estimates made by conservationists, around three million sharks are killed every year for squalene, which is also used in cosmetics and machine oil.

There are fears that a sudden rise in demand for liver oil could threaten populations and see more species become endangered.

Sea Turtles: The Endangered Species

Image
Sea Turtles have outlived almost all the prehistoric animals once they shared the planet. Marine turtles inhabit the oceans open waters and coastal habitats, feeding on jellyfish and other aquatic plants and animals. They are the live representatives of a group of reptiles that traveled our sea for more than 100 million years.  Importance of Sea Turtles These sea turtles have been living for more than 100 million years and maintaining a fundamental link in the marine ecosystem. They maintain the health of seagrass beds and coral reefs that benefit the valuable species such as lobster, shrimp, and tuna. Having outlived million years they can hold their breath up to five hours. They also transfer the vital nutrients from oceans to beaches and dunes. The seven extant species are The Green, Loggerhead, Kemp's Ridley, Olive Ridley, Hawksbill, Flatback, and Leatherback, which are endangered. Five of the seven species are found in tropical and subtropical waters. The other two sp

A Fish That Can Save The Coral Reefs

The reef provides a safe haven for millions of extraordinary creatures and plants. But if left grows unchecked they can literally kill the reef.  Parrotfish are the most important creatures when it comes to protecting the health of the reef. They eat the dead and algae-covered coral, allowing fresh coral to form and rebuild the reef. Without parrotfish, the entire reef will die quickly.  There are almost 95 different species which are found in coral reefs, rocky coasts, and seagrass beds, and can play a significant role in bioerosion. Each species has a different color scheme and can change their color as they go from babies to adults. This tremendous creature spends 90% of the day by eating dead algae and coral. When eating corals that contain rock, which then leads to white sand poo, a parrotfish can release up to 5 tons of sand per year. As participating in the hygiene of the reef their teeth become filthy, so every day they need a cleaning section. At the cleani

What Gives More Oxygen on Planet Earth?

Image
Everybody knows that plants and trees produce oxygen for the earth. But, do you know that oceans and seas contribute more oxygen. Produced by marine plants, algae and single-celled organisms called phytoplankton. These may not be seen by the naked eye but produce more, which is not even close to the proportions produced by the trees and plants. The ocean produces oxygen as a by-product of photosynthesis, which converts sunlight and carbon dioxide and can use as energy. One type of plankton, Prochlorococcus releases tons of oxygen into atmosphere. So small, that can millions can be present in a single drop of water. It produces 20% of the oxygen to the earth biosphere, which is more than the rainforests on land combined. Scientists mention that a single cell can give oxygen for one in every 5 breaths we take. Calculating the amounts of oxygen on oceans may vary because of the change in climate conditions, geographic location and with the tides. It is also important to remember that the
