Climate change has long been recognized as a global crisis with dire consequences for humanity. However, amid the headlines and discussions focused on the impacts on human lives, we often overlook the silent sufferers – the countless animals that also bear the brunt of the changing climate. As we find ourselves on the precipice of what experts are calling the 6th Great Extinction, driven not by natural forces but by human activity.
The scope of the challenge is immense, as nearly all species on Earth are feeling the effects of our rapidly warming planet. The intricate web of life, from the smallest insects to the largest mammals, is interconnected, and disruptions to one element can have cascading effects throughout entire ecosystems. As such, it’s challenging to rank the most affected animals definitively, but various organizations and scientific reports have attempted to identify those most vulnerable.
Animal agriculture, a major contributor to climate change, sets the stage for a tragic irony. While livestock farming is a significant driver of greenhouse gas emissions and deforestation, the animals themselves are suffering as a result of the changing climate. The intensification of heat waves and extreme weather events poses a dire threat to farmed animals like cows, pigs, chickens, and goats. Unable to escape their confined environments, these animals face the risk of heatstroke, forest fires, and suffocation.
Animals in polar regions, once adapted to frigid temperatures, are now grappling with the repercussions of melting glaciers and warming oceans. From polar bears struggling to find stable ice to hunt for seals, to narwhals and puffins facing habitat loss and disrupted food chains, these iconic creatures are at risk of extinction due to human-driven Climate change.
The often-overlooked insects, the backbone of many ecosystems, are particularly susceptible to climate shifts. Their sensitivity to temperature changes means that even a slight increase can have profound consequences. Studies suggest that as much as half of all insect species could see their ranges shrink dramatically if the Earth’s temperature rises by 3.2 degrees Celsius. Such changes could ripple through food chains and have cascading effects on other animals, including humans.
While some insects might flourish under new conditions, the overall balance could be disrupted, leading to invasive species spreading diseases or outcompeting native species.
Animals already on the brink of extinction due to habitat loss and human encroachment, like giant pandas, tigers, and orangutans, now face the additional threat of Climate change. Rising temperatures, habitat disruption, and dwindling food sources further jeopardize their chances of survival. These emblematic species are not just charismatic megafauna; they are indicators of the health of the ecosystems they inhabit.
The oceans, which cover more than two-thirds of the Earth’s surface, are absorbing the heat and carbon emissions that drive Climate change. This dual assault of temperature rise and overfishing is devastating marine ecosystems. Coral reefs, vital nurseries of marine life, are disappearing due to bleaching caused by rising temperatures. As marine species struggle to adapt to changing conditions, it’s predicted that nearly half of all marine species could be on the brink of extinction by the century’s end.
How Climate change affects animals are as varied as the species themselves:
Even our beloved pets are not immune to the impacts of climate change. Dogs and cats, depending on their breed and location, may suffer from heatwaves and increased pest infestations. As invasive pests spread due to changing climates, our pets’ health could be compromised, adding yet another layer of complexity to the climate crisis.
As the architects of this crisis, we bear the responsibility to mitigate its impact on animals and ecosystems. While individual actions alone may not reverse Climate change, collective efforts can drive change. Reducing carbon and methane emissions by cutting down on car and plane travel, as well as adopting plant-based diets, can significantly reduce our carbon footprint. Supporting climate action groups and advocating for regulations on fossil fuels and animal agriculture can catalyze broader change.

Even now, the notion that animals “exist for our sake” has strong resonances throughout popular Christianity. It is only right that theologians should now mock “the folly” of this notion, but such belated protests would carry more weight if they were offered in a spirit of some penitence. Folly it must be that sees the whole world as our plaything, but it has also been a grievous folly for those who have had to suffer it. We suffer least the folly inflicted on others when it affects us not at all. No wonder that…Voltaire could claim against Christians that “those who believe absurdities will commit atrocities.” Andrew Linzey, “Christianity and the Rights of Animals,” 1989
