Antarctica and Its Environmental Importance

Antarctica might appear to be a sterile, detached, and a chilly land at the bottom part of the earth, but its ecosystem is a significant factor in the health of the entire earth. The icy continent is not only very much intertwined with the globe but it is also co-dependent with the globe, that is environmental change on the planet affects the icy continent and in turn, the continent impacts the planet.

The Role of Antarctica in Earth’s Climate

Sometimes, Antarctica gets the name "Earth's refrigerator." One of the main reasons is that its gigantic ice platforms bounce a lot of sunlight (heat) back to the outer space thus helping in the control of earth’s average temperatures. Along with it, the ocean around the continent also plays a big role in climate regulation as it soaks large amounts of carbon dioxide and heat from the atmosphere.

However, this equilibrium is on the verge of changing. The demand for energy-related fossil fuels is the cause of the continuous increase in the atmosphere's average temperature, which also affects the oceans that in turn melt Antarctic glaciers faster thus, the shrinkage of the ice sheets continues. Less and less sunlight gets reflected when the ice melts, and more heat is absorbed, which is gradually increasing the temperature in the area in a very hazardous cycle.

Melting Ice and Rising Seas

Without a doubt, Antarctica is one of the most prominent sources of environmental issues and one of its major problem is the rise in the sea level. Ice masses in the western part of Antarctica and the Antarctic Peninsula are melting dangerously and glaciers are receding at a rapid pace, hence trillions of tons of fresh water are released into the oceans every year. The situation gets even worse, for example, if the ice that scientists talk about actually melts, sea levels on Earth would then raise over 50 meters.

This very extreme case would have happened after centuries, but the alterations which take place right now are not only putting coastal cities in danger but also far away island nations and their ecosystems.

Threats to Wildlife

The continent of Antarctica is the habitat of very famous species among others the penguins, seals and whales, these animals are the species which are the most affected by the stability of the ice and the sea. In the event of the sea ice melting, krill the small shrimp-like creatures that form the base of the food chain which nowadays are unable to find suitable places to reproduce the fact that has an impact on the whole ecosystem. Presently, emperor penguins are actually considered as "near threats" category because the icy habitats they are living in are rapidly diminishing.

Activities of human beings such as fishing and tourism inevitably bring added stress to the Antarctic, even though the place is so extremely remote.

The Global Connection

That which is happening in Antarctica has effects on other parts of the world apart from the continent itself. Ocean circulation changes due to the melting ice and circulation changes matter a lot in the distant weather pattern (e.g., the areas of North America, Africa, and Asia). Antarctic wind and ocean currents are profoundly interconnected with droughts, floods, and hurricanes in different areas of the planet.

In brief: it is not only the penguins that are victims of the situation which is going on in Antarctica rather, them along with the whole earth are the ones in danger.

What Can Be Done?

One of the most important things to be done is that gases which cause the greenhouse effect emissions have to be drastically lowered.

Additionally, the Antarctic Treaty, which has the purpose of preserving the continent from exploitation, is the thing that needs to be supported.

Fishing and tourism ought to be run in such a way that the industry will be sustainable and the resources will be adequate for the future.

Inject the topic into the forum— the more the public and policymakers understand Antarctica’s importance, the more likely they will be to demand action to curb climate change.
