You Won't Believe Which Animals Are the Real Heroes in the Fight Against Climate Change!

As the planet edges closer to irreversible damage, wild animals around the world are engaging in a secret fight against climate change and biodiversity loss. Despite repeated warnings from scientists, human activity continues to choke the atmosphere with heat-trapping gases, increasing global temperatures by approximately 1.4℃ compared to preindustrial levels. This rise has led to frequent bouts of extreme weather, causing thousands of preventable deaths and sparking trillions of Euros in damages. Furthermore, practices such as deforestation and extensive animal agriculture have severely disrupted biodiversity, pushing many species towards extinction.

However, amid this turmoil, wild animals exhibit natural behaviors that may help mitigate the impacts of climate change. Without these creatures, the future prosperity of our planet could be at serious risk. To mark World Wildlife Day on March 3, Euronews Green highlights the hidden efforts of these "superhero" animals in the ongoing battle against environmental degradation.

“Wild animals have a crucial role to play in addressing climate change, so it’s essential that policies are implemented to improve their welfare while safeguarding and restoring their populations,” says Ed Goodal, a climate policy specialist at the World Federation for Animals. “Protecting wildlife and their habitats is more than just a moral obligation but is the missing link in tackling the greatest challenge of our time.”

Wildlife's Role in Carbon Capture

Large herbivores like elephants and tigers play significant roles in their ecosystems and biogeochemical cycles. A 2019 study published in the journal Nature found that elephants in Africa’s rainforests reduced forest stem density, which altered the competition for light, water, and space among trees. These changes benefit larger trees with higher wood diversity, allowing them to absorb more carbon from the air.

According to WWF, just one forest elephant can increase the net carbon capture capacity of a forest by nearly 250 acres, equivalent to removing a year's worth of emissions from 2,047 cars. Similarly, a 2022 study published in Wiley revealed that forests with native tigers can store up to 12 percent more carbon per hectare due to their role in hunting herbivores like deer and wild boar, which would otherwise hinder plant growth.

The Impact of Digging Mammals

In Australia, species like the bettong and echidna help improve soil health by digging burrows and pits in the woodlands. These actions naturally trap leaf litter, enhancing soil nutrients and enabling better carbon sequestration. Additionally, the World Federation for Animals notes that these digging mammals aid in retaining moisture in increasingly dry forests, which are vulnerable to wildfires. Many of last year's blazes in Europe were exacerbated by human-induced climate change.

Moving beyond land, seabirds also contribute significantly to marine ecosystems. Excessive nutrient loads from human activities have harmed coral reefs, causing algae blooms that suffocate aquatic life. In the Baltic Sea, however, natural nutrient deposits from seabirds can actually support coral growth. A 2024 study published in Nature found coral colonies near islands with high seabird densities exhibited calcification rates up to 2.7 times higher compared to those near islands with lower seabird populations.

Marine Life and Ecosystem Health

Green turtles, having made a significant recovery in recent years, also play a critical role in marine ecosystems. In Australia, they consume seagrass seeds and transport them, sometimes covering distances as far as 650 kilometers. Alongside them, dugongs, commonly known as sea cows, also help in spreading seagrass, which is vital for carbon storage, especially in threatened areas like the Great Barrier Reef.

Finally, the iconic beaver stands out as a natural flood defense. Their dam-building activities can mitigate flooding, particularly important in a warming world where rising temperatures lead to increased moisture retention and heavier rainfall. A family of beavers recently made headlines in Czechia for constructing a dam that saved taxpayers approximately CZK 30 million (around €1.2 million). Research indicates that beaver-dammed areas are three times less affected by wildfires, preserving vital carbon-sucking vegetation.

As we confront climate change and biodiversity loss, it becomes increasingly clear that wildlife plays an indispensable role in maintaining ecological balance. By implementing policies that protect these creatures and their habitats, we can better tackle the challenges that lie ahead. Their role in our environment is not only a moral obligation but also a critical component in the fight for our planet's future.
