When the turtles are captured or tangled in nets‚ they are prevented from receiving oxygen‚ so the turtle drowns to its death. Fishing hooks have violently stabbed and killed the turtles (Callender‚ 2013). Another factor

result of this calculation is a starting requirement of 576.5 tons of iron ore fines entering the system to ensure 400 semi-processed tons enter the 2nd reactor. The 356.4 tons of outflow from the 2nd reactor (400 x 1- yield loss x 1- mass loss) is the input to the next step. We continued to take the outflow from each step and multiply by (1- the yield loss) to arrive at the final value of 321.5 tons of Hot Briquetted Iron (HBI)‚ per cycle. The number of cycles in a year was determined
