Warming Oceans Putting Marine Life ‘In a Blender’ By Jack Mcgrath

Due to ocean warming, lobster stocks in Southern England have fallen to the lowest levels ever recorded, putting lobster men out of business. This is because humans have been polluting the ocean more and more with greenhouse gases than ever. When these gases are released into the ocean, marine species begin to migrate towards the poles, and away from the Equator to avoid the heat.

Marine life migrating to higher latitude regions due to climate change

Global warming is mixing up ocean ecosystems, and scientists can't even predict what these new habitats will be like. When these species move to higher latitude regions of the ocean, competition of which species is better adapted will take place, resulting in natural selection and extinction of some species.

Marine species at risk of mass extinction due to ocean warming

Increase in ocean temperature has had a devastating impact on marine life. Extinction rates have sky rocketed in recent years due to the increase of pollution in the oceans. What we are doing is limiting the amount of livable conditions for marine life, resulting in a tragedy of the commons situation. When all of these species migrate from the equator to the poles, competition will take place and some of these new species will out-compete others. This will inevitably cause mass extinction of marine life.

Greenhouse gases being released into the atmosphere

This article is definitely noteworthy because it shows how humans alone can cause rapid extinction of species. Due to all of the carbon dioxide and other greenhouse gases being released, we are destroying ocean ecosystems by making certain parts of the ocean uninhabitable. Dr. Sunday said, “they’re limited by habitat and competition and all these other things keeping them in small ranges.” which is absolutely true. Because each species will move in order to stay in its “thermal niche," competition is inevitable. In order to prevent further extinction we need to crack down on solely relying on greenhouse gases, and make a switch to solar energy and other renewable energy sources.

My takeaway from this article is how global warming can have an environmental and political effect. Climate change not only affects ocean ecosystems and species, but it also has an impact on businesses. When certain species migrate, it affects markets such as the lobster stock mentioned in the article. The article mentions how lobster stock up north is higher than ever before, because all of the lobster species found down in southern New England have migrated up north. This article has shown me how environmental issues can branch out into other aspects of the world including political and economical
