Nuclear power stations require approximately one square kilometer of land per typical reactor. Environmentalists and conservationists have begun to question the global renewable energy expansion proposals, as they are opposed to the frequently controversial use of once forested land to situate renewable energy systems. Seventy five academic conservationists signed a letter, suggesting a more effective policy to mitigate climate change involving the reforestation of this land proposed for renewable energy production, to its prior natural landscape, by means of the native trees that previously inhabited it, in tandem with the lower land use footprint of nuclear energy, as the path to assure both the commitment to carbon emission reductions and to succeed with landscape rewilding programs that are part of the global native species protection and re-introduction initiatives.
