The study was conducted to determine the awareness and sensitivity of the younger generation in environmental issues such global warming, climate change and waste management. Data were gathered from selected students who attended the environmental awareness seminar held at Lyceum of the Philippines – Laguna in 2011. There were 54 students who participated in the survey. The respondents had participated in several activities related to environmental issues which include attendance to seminars, and participation in school and community projects. Most of the information about environmental issues was obtained by the students from their teachers. Global warming was the most common issue. There was a significant increase in the level of knowledge after the environmental awareness campaign was made. As a result, the highest level of action proposed by the students is on the proper disposal of wastes and the proper segregation of wastes.
