Species most at risk include those with specialized habitats or diets, such as polar bears, sea turtles, and certain amphibians. Animals living in fragile ecosystems, like the Arctic, coral reefs, and rainforests, are particularly vulnerable as climate change accelerates habitat degradation and disrupts ecological balance.

Humans can help by reducing carbon emissions, preserving natural habitats, and supporting conservation efforts. Protecting ecosystems, such as wetlands and forests, is critical. Additionally, promoting sustainable practices, reducing pollution, and advocating for policies that address climate change can make a significant difference.

Keystone species, like sea otters and elephants, play a vital role in maintaining ecosystem health. For example, sea otters help protect kelp forests, which absorb large amounts of carbon dioxide, while elephants spread seeds that support forest regeneration. Preserving these species helps sustain ecosystems that mitigate climate change effects.
