If intervention is maintained and work continues to go on and make progress as it has been doing then species diversity could again increase, with natural environments throughout the world improving¹. However it is likely that within a few decades many species which are a common sight today could have disappeared from the wild. As the world becomes economically richer it becomes biologically poorer as natural wild habitats are replaced with human settlements or resource areas eg farms². The future of conservation and its success is still unclear and will depend entirely upon investment of time and money and whether or not it is now too little , too late.
