[245] [246] [247] Pile-driving to construct non-floating wind farms is noisy underwater, [248] but in operation offshore wind is much quieter than ships. [249]

    Lacanja burn shows deforestation. Human population growth results in changes in land use, which can cause natural habitats to become fragmented, altered, or destroyed. [5] Large mammals are often more vulnerable to extinction than smaller animals because they require larger home ranges and thus are more prone to suffer the effects of deforestation.
