one professor asked me "you professor in what? Recycle? you should focus on biology". very good question from microscopic professor. 32 years ago I proposed two subjects called wildlife ecology and ecotoxicology. I told my students that these two courses are future subjects for developed country Malaysia. WHY? Malaysia is top 12 mega-biodiversity in the world and we must work hard on the ecology, genetic and systematic of the flora and fauna in Malaysia. We must protect the ecosystems, assess the chemical pollution and status of general pollution. Industrial , agricultural and urbanization will effect the wildlife habitat and in turn will effect the human being. Now every year during international earth day, world environmental day and other habitat celebration people will talk about habitat loss and chemical pollution. This year people are talking about plastic pollution. My ideas 32 years ago now is becoming real challenge.
