However, the event is not without its criticism. Some complain the activity is dangerous as it allows for criminals to be more active under the cover of darkness. This is specially troublesome in those cities with high population density. Others ensure the event is useless as the energy carbon reduction during that hour is not enough to have any significant impact on the planet. Nevertheless, Earth Hour coordinators indicate that the intention of the activity is to create awareness of the “ecological footprint” of institutions and individuals worldwide.
