Fish nearly extinct in China's largest desert freshwater lake
Fish in Hongjiannao Lake, China's largest desert freshwater lake, are on the border line of extinction due to changes in their habitat. Fishery authorities have seen how the lake has shrunk and has increased in salinity. This in turn affects fish species as they have already noticed. The lake's water level has decreased by 20 to 30 centimeters every year. This indicates the delicate this case is and the importance of finding a solution to this problem.

Effects of climate change to further degrade fisheries resources: UBC researchers
Climate change has highly affected fish and consequently fishermen. The reason for this is because fish change in reproduction, growth, and distribution due to temperature change. This causes fisheries to be economically affected. University of British Columbia researchers have seen the differences in size and quality of fish reacting to climate change. They fear that fisheries will not be able to supply the high demand of fish on Earth. Overall climate change has once again shown to have negative effects that without a stop to them will continue to alter our planet.
