  • I have viewed this powerpoint on pollution and I found it very useful and informative with good illustrations. I would like to request you to send it to me by email since I can not download it. I am teaching here in Africa and it would be very useful for my students. My email is muchinesu@yahoo.com
    With thanks in anticipation.
