People have altered species or their genetic compositions by domesticating them, inducing changes in wild species, changing habitats and structures, introducing exotic species, changing species behaviors, migrating to new areas and changing habitats, and hunting. Species conservation is already being promoted, with a first step already underway of making inventories of all and endangered species. Individual species are beginning to be protected under various laws and treaties. And, various conservation groups are trying to identify specific areas to preserve or conserve. More habitats could be provided by proactively maintaining them while managing forests for timber. Landcare, restoration of habitats, is being done as a business in Australia. A mitigation bank could be established to compensate countries with high biodiversity for protecting it. Legally preventing movement of raw organic materials between floristic realms could stop invasive exotic species. We can accept some “novel” ecosystems that consist of species that never been together before. We can replace extinct species with existing, analogous species. And, hunting can be done in a way that promotes biodiversity.
