Fish is one of the world's favorite foods. Around the world, the average person eats 36 pounds (16 kg) of fish every year. But many kinds of fish around the world are disappearing because people catch too many of them. Scientists say that 90 percent of the biggest fish are gone now. If we catch too many big fish now, there won't be any baby fish in the  future. Some species of fish will become extinct. Our way of fishing now is not sustainable— if it continues, it will hurt the environment.
