koala

Iconic marsupial of eastern and southeastern Australia, koalas weigh up to 15 kg and spend up to 22 hours daily sleeping to conserve energy from their low-calorie eucalyptus leaf diet. Highly specialized to process toxic eucalyptus compounds that would kill most other mammals, they have gut microbiomes uniquely adapted for detoxification. Listed as Endangered in 2022, with populations decimated by chlamydia disease, habitat clearing, and climate change.

Rice

The most important food crop in human history, rice feeds over half the world's population and is the staple grain of Asia, Africa, and Latin America. Domesticated from wild Oryza rufipogon approximately 9,000 years ago in the Yangtze River valley of China, rice cultivation has shaped civilizations, landscapes, and ecosystems. Its flooded paddy cultivation creates extensive wetland habitats for migratory birds, amphibians, and aquatic invertebrates while producing significant methane emissions.
