Two ecologists, Dr. White and Dr. Grey, conducted a comparative study on the effects of urbanization on local wildlife populations. Dr. White hypothesizes that urbanization severely disrupts wildlife habitats, leading to declining animal populations and increased competition among species for limited resources. In contrast, Dr. Grey argues that urban areas, if well-planned, can support diverse wildlife populations by providing new food sources and nesting sites.
Based on these hypotheses, which of the following statements best reflects the main focus of their conflicting viewpoints?
