Fish population is in serious danger from global warming. Climate change is increasing the water temperature in rivers, lakes and seas. This means there is less food and oxygen available for fish. It also means the fish may not grow fully and may have fewer offspring. Some fishes will become extinct if temperature rise even by one or two degrees.

Climate change increases the pressure on fish population. Fishes are one of the world's most valuable biological assets. Forty percent of people in the world eat fish ar their main source of protein. If we fail to reduce greenhouse gas emissions, we will increase the pressure on fish.As a result, people who depend on fish will suffer from hunger and poverty.
