Sky Tower

The provided articles focus on the "Earth Hour" initiative, a global event organized by the World Wildlife Fund (WWF) to raise awareness about climate change. The articles highlight the participation of numerous cities and towns in Germany, where prominent landmarks such as the Brandenburger Tor in Berlin and the Kölner Dom were plunged into darkness for one hour. This symbolic act aimed to demonstrate a commitment to environmental protection and encourage greater action on climate change. The articles do not mention Sky Tower, therefore, I cannot provide information about it based on the given context. The news is relevant as it showcases a global effort to promote environmental consciousness and sustainability by engaging iconic structures and communities worldwide.
