2)The Oceans Most Important Predators Being Killed... But Just For The Fins
Tens of millions of sharks are killed every year and only a very small portion of the shark is utilized. Sharks are often killed for their fins to be sold as a very expensive and popular ingredient for soup. The way that these sharks are killed is atrocious. A common practice is to catch sharks, cut off their fins and toss them back in the ocean to die. Not only is this horribly wasteful but it is disgustingly inhumane. Not only are they murdering these animals but they are leaving them in the ocean to die of a very slow painful death, essentially leaving them to drown. Without their fins these sharks are unable to swim or do anything, it is not the cutting off of the fins that kills them it is the inability to move. Sharks are considered one of the oceans top of the food chain predators. This means that they have a very slow reproduction rate compared to other marine creatures. It also means that they regulate many species within the marine ecosystem, meaning that if sharks were to become endangered, it would drastically change many aspects of the marine ecosystem. It would cause serious over population in many other species that would cause a destructive change in the food chain and relationships between other species. In order for our oceans to maintain balance shark fining must end.

, Jennifer Jacquet, a PhD student at the University of British Columbia (UBC) Fisheries Centre (who is working with the renowned
Dr. Daniel Pauly
), writes about a new study on which she was the lead author, entitled "
Hot Soup: Sharks Captured in Ecuador's Waters
" (sub. required). She and her colleagues found that the Ecuadorian government failed to report the catching of around half a million sharks each year."

New Study Finds Half A Million Sharks Are Fined Every Year In Ecuador
The PreCambrian Era can be defined as the stretch of time from the formation of earth to the beginning of Cambrian Time. This period occurred approximately 4.6 billion years ago. Because it is such a long period of time, it can be broken up into three sections or eons: Hadean, Proterozoic, and Archean. The precambrian era began with the hadean era, this is where the earth's atmosphere and oceans were formed. No organisms were formed in this era. The Archean eon was approximately 1.5 billion years ago and is responsible for the formation of the very first life here on earth. This eon is where plate tectonics established, Archean is divided into three subsections. During the Archean eon the earth's crust cooled enough for rocks and continental plates to form. The most recent of eons is the proterozoic eon, this is where eukaryotic celled organisms appear. Also, organisms with the ability of sexual reproduction are first seen here. This eon is known for the production of cyanobacteria

Notes- Quotes from
-blue green algae
these bacteria formed extensive slimy carpets in shallow coastal waters, and before the end of Achaean-time 2.5 bya had also formed a thin crust on land known as stromatolites"^Arrangement of countries in precambrian era
-" Cyanobacteria, photosynthetic Eubacteria that produce oxygen as a metabolism byproduct may have appeared of early as 3.5 billion years ago, but became common and widespread in the Proterozoic"
-"eukaryotic celled animals appear as fossils, These are the organisms that most people are most familiar with - all animals, plants, fungi, and protists which share fundamental characteristics such as cellular organization, biochemistry, and molecular biology"
