``Everybody talks about Mumbai's environmental problems, but very few seem to be able to pinpoint what exactly ails the city, and more importantly, what can be done to correct it. My programme is aimed at school-going children who need to know what these problems are so that they could do something about them,'' Aditya told Express Newsline. The 40-minute audio-visual, with Aditya's voiceover accompanying the pictures, will soon be exhibited in his ownschool for the 25th time.

``I would be glad if even a few students, at the end of it, begin to treat nature more sympathetically,'' says Aditya, as he readies himself for what he calls ``a dress rehearsal.''
