Does Animal Liberation Affect or Harm the Ecosystem Significantly?

If animal liberation affect or harm the ecosystem significantly, then surely commercial fishing does more harm.

National Geographic agrees to this.

Fish Crashes Due to Overharvesting

Christensen and his colleagues analyzed more than 200 models of marine ecosystems from around the world to estimate fish numbers between 1880 and 2007. They found that 54 percent of the decline in predatory fish populations had occurred in the past 40 years.

“Cod in the North Atlantic is a classic case of a crash,” he said. “You had hundreds of years of sustainable fishing of cod—on the order of 200,000 to 300,000 tons caught a season—and then we saw an increase up to 700,000 tons, beyond sustainable levels.

“Now it’s been 20 years and we still haven’t seen a recovery.”

Those who want to protect the natural ecosystem should stop commercial fisheries and fishing companies from upsetting the natural marine ecosystem.  A direct way is to stop eating marine life, and start campaigns to raise awareness about it.  As they say it, “When the buying stop, the killing stops”.

And when the commercial fishing stop, animal liberation of respective marine life do not and cannot even take place.

It is laughable when I read articles about how animal liberation can significantly upset the marine ecosystem when commercial fishing companies easily destroy the balance by wiping out tons of marine life every season.

So jog my memory again, how many tons of marine life have we liberated last year?

(Hint: Not enough tons.)
