It’s no secret that climate change has an adverse effect on the future of our planet. From increasing temperatures to rising sea levels to melting ice caps, the effects of climate change are real. Depending on who you ask, the cause of climate change is still up for debate. Some say it’s a natural cause of the planet changing, while others will say humans are contributing to the effects of climate change. One certain event that can’t be disputed is the food supply. In my previous article, I talked about how rising temperatures are affecting wine production. Well, this change is not limited to only wine. Now, it seems that the majority of fish will be affected by climate change. Listed below is how our food supply will be shaped from climate change with the change in fish population. 

The increase in temperature: 

The temperature of the planet and water have increased yearly. Unfortunately, fish cannot adapt to extreme temperatures, unlike humans. Humans have technology that allows us to cool down, however, fish do not have the same luxury. A marginal temperature increase affects less fish, but it is predicted the temperature will rise 41 degrees Fahrenheit in a worst-case scenario by 2100. Up to 60% of fish could have difficulty surviving and adapting to this temperature increase. The offspring may easily succumb to the temperature increase as well. 

The population of fish: 

Let’s take the worst-case scenario into consideration. If 60% of fish will be affected by climate change, that will cause the fishing market to decrease exponentially. Less fish in the water also affects the stability of the food chain. Predators like bears and penguins must rely on other food sources to survive. For them, it’s more difficult to change their prey. We may begin to experience certain predators die out due to a lack of food. Not to mention, humans consume fish as well. For those whose eating lifestyle is primarily fish, they will have to have alternative meat options to meet their needs.
