Whilst most emergency services agree on protecting human health, life and property, the environmental impacts are not considered sufficiently important by some agencies[citation needed]. This also extends to areas such as animal welfare, where some emergency organizations cover this element through the "property" definition, where animals owned by a person are threatened (although this does not cover wild animals). This means that some agencies do not mount an "emergency" response where it endangers wild animals or environment[citation needed], though others respond to such incidents (such as oil spills at sea that threaten marine life).
