Oceans are being depleted of oxygen due to climate change and run offs

The video discusses how climate change and nutrient pollution are depleting ocean oxygen levels. A report highlights that nitrogen and phosphorus runoffs from sewage, agriculture, and industrial pollution are major contributors, especially in coastal areas. Climate change is also heating oceans, reducing their oxygen capacity. The study reveals a 2% global drop in ocean oxygen, with up to 40% in tropical regions. This deoxygenation affects marine biodiversity, harming larger fish like tuna and sharks, while benefiting microbes and jellyfish. Fish are forced closer to the surface, increasing their vulnerability to overfishing.
