When we think of marine habitats, we can imagine diverse, tropical creatures living in the ocean. Over the past decades, citizens and the governments have dedicated too much attention to mass production. These fumes that came out as a byproduct of mass production sped up the climate change rate exponentially. Recently, scientists illuminated a research, that climate change has been taking effect not only on land, but in the ocean as well.

Climate change is really damaging the fish population in the world’s oceans and rivers, and scientists have collected some facts that show just how bad the problem is. A big study found that from 1930 to 2010, sustainable fish catches dropped by about 4.1 percent because ocean temperatures warmed, and in places like the East China Sea and the North Sea the losses were as high as 15 to 35 percent. This means there are millions of fewer tons of fish in the ocean than there used to be because of climate change making waters warmer and harder for fish to live in. Marine heatwaves have also increased by more than 50 percent in the last 30 years, which messes up fish habitats and can kill fish that are sensitive to temperature changes. Areas near the equator could see fish catches drop by up to 40 percent by 2050 if the water keeps warming. These changes make it harder for fish to find food, reproduce, or stay in the places they have lived for years, and that affects people who depend on fishing for food and jobs too. 

A few thousand meters up to the north and the south pole, polar bears and penguins have been under great pressure of melting ice. Due to the global temperature increasing, the glaciers and ice continents disappear. Research shows, conducted by scientists in the following area, that the meltdown of the ice is a huge 12.4% every decade. Scientists have rose to a conclusion that in this rate, the ice in the north and south pole will be 50% gone in the span of 100 years.

Citizens globally acknowledge the detrimental damages our actions have caused. Thus, we have been attempting to mitigate this harm through means such as decreasing the net usage and disposal of plastic, advocating for cleaner, greener companies, and some corporation even substituting their products with materials that are way cleaner. However, as the climate change rate never stopped completely, this topic is still a huge problem to consider and requires more than enough of attention that we currently do.
