Fish Could Die Out from Climate Change

In the Antarctic, fish adapted to the very cold waters with antifreeze proteins to help them survive. Hundreds of species there evolved after a period of rapid cooling tens of millions of years ago. You might expect temperature changes resulting in mass die offs and adaptions would be large, but in some cases even small temperature changes can cause large impacts. Research conducted at Yale University indicates even a two degree increase in Antarctic waters could lead to extinction of local fish.

“The development of polar climatic conditions that shaped the [evolution] of Antarctic fish is now reversing. The increasing temperature of the Southern Ocean, with the potential for the arrival of invasive species and disruption of food webs, is the greatest threat to the survival of this unparalleled [diversity],” said Yale ecology professor Thomas Near.

Some people might not particularly care about the Antarctic fish, but they are a significant food source for penguins and seals. Some of the penguin species living in the area of Antarctica are Emperors, Adelies, Chinstraps, Gentoos, Kings and Macaronis.


One of the main contributors to climate change from humans is livestock agriculture. About 51 percent of climate change gases are created by it. So reducing one’s meat consumption is a good way to shrink climate change emissions. The lesson that everything is connected in Nature, seems to be a challenging one for the human species to learn.

The effect of livestock agriculture on climate change is very disturbing and needs to be reported more widely in the media.

reduce, reuse, recycle, educate, sad what we are doing to our home...our children will suffer the actions of the past generations selfishness and greed....hope we have the humility to make changes to our lifestyles that will preserve as much as possible for all life.....

there is no planet b for life...lets save the one we have.

The tropical coral reefs are also in danger. The ocean's increased heat allows it to dissolve more carbon dioxide, which makes it more acidic. Coral has a calcium carbonate exoskeleton, and you can imagine how it reacts to acid. All of the fish and other creatures there depend on the coral to survive.

The fish in the Antarctic are amazing. They also have crazy creatures like giant starfish that span well over a foot. Really incredible.
