1)stocks of bluefin tuna have dropped by 80%.what reasons are given for this and other population declines seen in commercial fish? 2)why is bluefin tuna particularly at risk?

Stocks of Bluefin Tuna, and other fish populations, have dropped by eighty percent due to illegal fishing activities and over-fishing done by humans. Bluefin Tuna are popular to catch because of their large, domineering size.

Bluefin tuna are considered a delicacy for sushi and sashimi and are sold for a lot of money. Due to the potential high earnings in return for this species of fish, fisherman are highly motivated to capture Bluefin tuna, putting them at higher risk. This is a problem because Bluefin are large and fast, making them a top undersea predator. Their deaths in large numbers upset the food chain balance under the sea.

answer: cannibalism, the capac raymi, capacocha, the eight day feast, the combing of the hair

explanation:

the incas have many rituals, cannibalism was always a very ritual thing, which was normally tied to sacrifices, warfare, death, and regeneration.

  the capac raymi was one of the most important ceremonies. it occurred around the summer solstice and was when they worshiped their sun god, also known as inti.

  the capacocho was another one of their most important ceremonies. it was when many children where selected to start their training, and these children where destined to become sacrificial blessings to their sun god, inti. being chosen for this ritual was a blessing.

  the eight day feast was a feast that lasted 8 days and, each day, the day began with a chanting at dawn. a follow up song at noon. which ended with complete silence at the end of the day. on this day, inca royalty was always dressed in silver and gold laced clothing.

  the combing of the hair was the most important ritual to young girls. this ritual was known as the coming of age ceremony, but only the most beautiful girls where chosen. in this ceremony, the girls chose their new name and where chosen as either brides, or princesses of rulers.
