Let's evaluate each statement regarding 'Earth Hour': 1. **It is an initiative of UNEP and UNESCO.** This statement is incorrect. Earth Hour is a worldwide movement organized by the **World Wide Fund for Nature (WWF)**. It started in Sydney, Australia, in 2007 and has since grown into a global event. UNEP (United Nations Environment Programme) and UNESCO (United Nations Educational, Scientific and Cultural Organization) are not the primary organizers. 2. **It is a movement in which the participants switch off the lights for one hour on a certain day every year.** This statement is correct. Earth Hour encourages individuals, communities, and businesses to turn off non-essential electric lights for one hour, typically on the last Saturday of March, as a symbolic gesture of commitment to the planet. 3. **It is a movement to raise the awareness about the climate change and the need to save the planet.** This statement is correct. The primary aim of Earth Hour is to raise global awareness about climate change, biodiversity loss, and the urgent need for action towards a sustainable future. Therefore, statements 2 and 3 are correct.
