I agree. Looking at figures globally
Killer wales on average kill 551 pounds of fish a day x by estimated population of 50000 that is 27550.000 pounds of fish a day. over one year is 10055750000 pounds of fish a year. divide that by a ton 2000 pounds = 5027875 Tons.
And, fish play an outsized nutritional role for many people;
3.1 billion people rely on fish for 20% of their daily protein intake, with some coastal communities reliant on fish for upwards of 70%. that consume
31000000000 x 2 ounces per day: 32000 ounces per ton 31000000000 divided by 32000 = 968750 tons a day x by year 365 days = 353593750 tons per year.
Human consume globally 353 Million tons per year. Killer Whales 502 thousand tons per year. Under 1 percent.
They say 27% of fish caught from fishing is wasted. that 95 million tons waste per year from poor fishing practices. Fishing is not infinite resource that is why best practices are need to reduce wastage and killing of non target fish a food source for killer whales as well as other marine animals.
You see the wasted fish below
