More than a day of celebrations, this has been a full week of Earth Day related events! Some volunteers were still cleaning Angel Island and other California parks on Saturday. In its 40th year, Earth Day has grown to become a global landmark and the occasion for major Government and Industry announcements. In the economic downturn green initiatives have also found new depth and gained in realism. One clear trend from last year is the focus on energy efficiency across industries (supporting renewable energies and developing environmental consciousness were the highlights of 2008) as a way to reconcile economic realities and the need to fight climate change.
