H2O heats up: The threat of fish

Fish market in New York

According to the report recently published by the environmental protection organization WWF, fish species are increasingly threatened by the rise of temperature in rivers and lakes, as a result of climate change.

The report is titled ' Are we raising fish in hot water?' explained to us that the hotter the water, the less oxygen it contains and the less favorable it is for the reproduction of fish.

According to WWF's marine program manager, Katherine Short, fish die in large numbers due to overfishing and environmental pollution. The increasing effects of warming climate inevitably cause imbalance.

According to Ms Short, it is necessary to protect fish species, because they are our most valuable biological resources, food sources and economic resources. The increase in temperature will affect the reproduction of some fish species. In addition, some fish such as salmon and sturgeon cannot lay eggs if the temperature is too hot. Fishes are also at risk of suffocation in an overheated water environment, because the higher the temperature, the less oxygen there is.

Under these circumstances, fish species tend to migrate to areas with cooler water sources, which will have a very bad impact on other species whose main food depends on fish.

This report was released a week before the meeting parties discussed the Tokyo protocol in Montreal. Therefore, WWF has called for all countries to further reduce CO2 emissions.

WWF European climate program manager Stephan Singer warns: We have not succeeded in significantly reducing the amount of gas causing greenhouse effect while billions of people are waiting for it because of the source Their eating is increasingly destroyed.
