Written solution:

Since we have $1$ birth every $8$ hours, we have $3$ births every $24$ hours. Therefore, we have $3$ births a day and $1$ death a day. The net change in population every day should be on average $2.$ Since we have $365$ days in a year and $2$ added to the population every day, the net change in population should be around $2\cdot 365 = 730 .$ This is approximately $700.$

Thus, the answer is B .
