BIOLOGY
I have learned a little about in-vitro fertilisation in Biology recently this year, and learned the beginnings of genetics which we will be studying in 5th year. I wrote a project about the disease, cholera and also did a poster project on sharks. Please scroll down to read more about sharks and also take a look at my project on cholera.

This is some of the information I obtained by researching on the internet. I found almost all these facts from sharks-world. I thought that the many issues facing sharks were shocking and I wanted to share this section of my project with others. I think that the treatment of sharks and marine life in general really needs to be changed and that it should be a priority to all people to make the sea a better and cleaner place. Many species are becoming extinct due to over-fishing and polluted water. If we do not make an effort to change the situation and continue to ignore all life under water, it will end up affecting us badly. If you take the time yourself to read more about the issues facing marine life, you will most likely feel as passionately as I do about the matter. Thanks for reading...
Some information about sharks from my biology project:
Shark Facts
Due to wrong publicity, sharks have a bad reputation. However, as you learn their main facts, you will appreciate them for what they really are...
Sharks have very few natural predators which allow them to freely move to new habitats when food is scarce. They are loners for most part of their lives so they don’t travel together
Many people believe that sharks only live in oceans however, they are distributed in many different bodies of water.
There are over 300 different types of shark species in the ocean, but they all share the same basic anatomy. Anatomic shark characteristics, such as shark tails, which allow them to swim quickly, have made them ruthless predators.
Sharks have roamed the sea for 400 million years, pre-dating dinosaurs by 200 million, and unlike many creatures have remained almost completely unchanged
For every human killed by a shark, approximately two million sharks are killed by humans, totalling around 73 million sharks killed annually.
Issues facing sharks
By 2017, it is estimated that 20 species of sharks could become extinct
Even Marine reserves like Cocos and Galapagos where sharks are supposedly protected, are the target of illegal fisheries.
Sharks are slow to reproduce and cannot sustain the massive fishing pressures they are under.
In 2009, the UCN reported that 1 in 3 of all shark species are threatened by extinction.
Research indicates that up to 73 million sharks are harvested and sold, annually, mostly for shark fin soup.
To obtain fins, fishermen often engage in shark finning at sea. This is a brutal process which involves slicing the fins off a live shark and then throwing the shark back into the ocean to die.
