The documentary highlights global efforts to protect endangered species and nature reserves, focusing on various conservation projects such as the reintroduction of lynxes in Germany, the protection of manatees in Florida, and the study of jaguars in the Amazon. It also addresses the challenges faced by these efforts, including habitat destruction, poaching, and climate change, emphasizing the need for sustainable conservation strategies and the involvement of local communities.

Since 2005, the Brazilian government has been actively working to shut down illegal sawmills, which contribute to deforestation and environmental degradation. Despite these efforts, illegal logging remains a significant threat to the Amazon rainforest, impacting global climate and biodiversity, although there is hope in the forest's natural ability to regenerate.

The chapter highlights the critical situation of rhinos, whose numbers have drastically decreased due to poaching for traditional Chinese medicine. Conservation efforts, such as rescue missions and constant monitoring by rangers, are crucial to prevent their extinction, despite the high risks and costs involved.

Ranger Ola Anders and scientist Ulrich Muller are dedicated to studying the elusive lynx in the Harz Mountains, using telemetric technology to track and understand their movements and behaviors. Despite challenges, such as the temporary loss of signal from a tagged male lynx, their efforts have led to successful monitoring and reintroduction of lynx into the wild, offering hope for the species' future in Germany.
