The world is undergoing some serious changes in the last few decades and populations are decreasing at an alarming rate. If the human race doesn’t take action, global diversity will fall, bringing species to extinction.
Species and populations all around the world are becoming victims of global warming. In recent news, raging fires and destroyed habitats are pushing koalas slowly into extinction. Human urbanization is taking over the koalas’ land, cutting down eucalyptus trees, their main source of food. Will humanity ever stop its worldwide rampage? Is there even a small possibility to save the species we care about and want to preserve? With global warming effects being more prominent than ever before, we are running out of time.
Severe climate change can cause changes in average temperature which can be devastating to many species that live in specific temperatures. The increasing temperatures of up to 9 degrees can completely ruin Australia’s great barrier reefs, as well as other habitats. Hotter climates in the Arctic affects more than just the Arctic. It ultimately affects the world on a global scale, causing numerous fires in forests, further destroying the homes of many different species.
In addition to climate change, pollution is playing a significant role in affecting world diversity. Pollution in nutrient loading, such as high concentrations of atmospheric nitrogen, can overly enrich habitats, causing eutrophication. Lakes and ponds are greatly affected, and the species within them are killed due to the high density of nitrogen and rich minerals in the water. Air pollution and physical waste in oceans are also causes of biodiversity loss. Oil spills and sewers leading to oceans can kill off many coral and fish species, affecting the ecosystem and food webs. Air pollution can result in acid rain, which damages trees and other plants.
A great factor in overall decreasing biodiversity is the role of human activity. As well as being the reason behind many examples of pollution and climate change, there are many things that humans do that directly affect organisms. Humans are taking over all of the available lands on Earth and using it to urbanize and build, forgetting about all of the species that live there. Humans cut down trees, unknowing of the organisms that make that tree their own.
The world is falling apart at an alarming rate, and the species within it are losing their populations to climate change and pollution and major human activities. The time to act is now because the earth is running out of time. If you want to make a difference, do the most you possibly can: from picking up some litter to cleaning beaches from plastic. If everyone takes part, then we can save the Earth’s biodiversity!
