Lesson 4:putting

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 temperatures 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 as their main source of protein. If we fail to reduce greenhouse gas emissions,
we will increase the pressures on fish. As a result, people who depend on fish will
suffer from hunger and poverty.
