Final answer:
The environmental movement is largely a unified political movement due to the centralization of environmental organizations.
Step-by-step explanation:
The statement 'Given the centralization of environmental organizations, the environmental movement is largely a unified political movement' is true.
The environmental movement, which aims to preserve and protect the natural environment, has become largely unified due to the centralization of environmental organizations. These organizations work together and share resources, such as databases and websites, to recruit members, publicize their activities, and pursue policy objectives. One example is the Save Our Environment Action Center, which consists of twenty national environmental groups pooling their resources.
Through this centralization, environmentalists are able to coordinate their efforts and advocate for common goals, such as addressing the climate crisis and protecting biodiversity. However, it is important to note that there may still be different factions or approaches within the environmental movement, but overall, it can be considered a unified political movement.
