Earth Time Now! is the annual youth conference planned by the Student Environmental Network (SEN), held for the first time in 1997. In planning the annual conference, students learnt about public speaking, workshop moderation, conference procedure and recording. The objectives of Earth Time Now 1997 were to inform students about environmental issues and to give them an opportunity to voice their concerns to leaders in government and business. Earth Time Now! 1997 was problem-centred and students learned about a range of environmental problems affecting Jamaica.

Earth Time Now! 1998 was solution-centred. The theme was "Human Habitats" and the conference focused on visions of better cities. The 2001 conference was on Kingston Harbour, in 2002 the theme was global warming and in 2003, students learned about Jamaica's forests. Members of SEN have addressed parliament on environmental issues, interviewed the Prime Minister, attended international conferences and conducted media tours.
