AN SDG #13 ANALYSIS — GLOBAL WARMING AND ITS IMPACT ON ECOSYSTEMS

Analyze the effects of global warming on ecosystems, focusing on biodiversity, habitat loss, and species extinction. How can governments, organizations, and individuals mitigate these impacts and promote environmental sustainability? Use evidence-based examples to support your discussion.

The Earth’s temperature has risen significantly over the past century, altering natural systems that have existed for thousands of years. Its prevalence over global and widespread areas has contributed to different solutions and initiatives aiming to combat the phenomenon. Moreover, numerous scientists and researchers have hypothesized that the inhabitants of Earth, the humans, have played a major role in the changes of the Earth’s atmosphere in a dramatic manner throughout history. As a result, global warming is now in the hands of its abusers. To understand the concept of global warming, familiarity with the greenhouse effect should be a focus. The increasing contamination of gases, such as carbon dioxide (CO₂), methane (CH₄), chlorofluorocarbons (CFCs), and nitrous oxide (N₂O), is called the greenhouse effect. Human activities, such as the burning of fossil fuels, increase the amount of these gases in the atmosphere. The greenhouse gases absorb infrared radiation, preventing its escape into outer space. Volcanic eruptions and forest fires also contribute to the vast amounts of greenhouse gases. In turn, greenhouse gases from all sources mix in the atmosphere and affect the entire Earth. Global warming, driven primarily by human activities, is severely disrupting ecosystems by altering habitats, accelerating species extinction, damaging marine and terrestrial environments, and indirectly threatening agriculture and human health. Overall, it affects ecosystems.

On marine ecosystems, ocean acidification, coral bleaching, and rising sea levels due to global warming have a huge impact. The acidification of the ocean occurs when there is an absorption of carbon dioxide, lowering pH levels. As a result, coral reefs and shell-forming organisms face significant harm. Coral bleaching results in warmer temperatures, leading to the loss of marine biodiversity as it disrupts many interconnected food chains. Furthermore, the rising sea levels melt glaciers and polar ice, destroying coastal wetlands and mangroves, which is a threat to marine species and nesting grounds. Terrestrial ecosystems also face droughts, wildfires, and extreme heat. Species shift into other environments, such as poles and higher elevations. Building on that, native and invasive species compete for their lands, risking extinction for organisms unable to adapt. Biodiversity loss through reduced ecosystem stability and marine damage is also evident. Through active measures such as raising awareness in different places, global warming’s mitigation can be introduced. Our government can provide systems that can recognize its importance and ways to solve or reduce the phenomenon of global warming. Moreover, sustainable actions such as the transition to sustainable resources should be a key priority. In general, global warming is not a laughing matter. It is significant and needs to be addressed.
