Photo Contest Santiago, Sainz-Trápaga, Argentina A life cycle in the marine world: a majestic dead whale has washed ashore, and petrels feed on the feast it provides for weeks. This scene reflects the crucial interdependence of species in marine ecosystems, where the death of a gigantic creature like the whale triggers a celebration of life for other species. This symbiosis highlights the importance of biodiversity and the vital role played by scavenger species in preventing waste accumulation and reintroducing essential nutrients into the food chain, thereby contributing to the balance and health of ecosystems. Geoffroy´s cats fate, Argentina In the rural regions of South America, the tradition of hanging dead animals on the fences of fields reflects the relationship between rural communities and the land. However, it can also contribute to biodiversity loss. Displaying felines as trophies involves hunting and poses a threat to their populations. Furthermore, by acting as a barrier to other animals, this practice disrupts ecological processes and challenges biological diversity, ultimately disturbing the natural balance and impacting wildlife in the region over the long term.
