I have a very important cultural competition the topic is WATER: uses, pollution, how to preserve this important natural resource, its future. I need to make a speech about this topic, I need materials and I have to prepare a power point presentation for my ss presentation, but I have been looking for information, I need images and I already looked up on the web but the images and information hasn �t changed since last year. Could you help me please? Give me a good site, where I can I get images and information. Because this year one of my resolutions, was to win this competition. You can send me all kinds of information because I �m not really good at preparing speeches.  I really appreciate your support. thanks in advanced.
