  • 44:54 - Acid Rain's Legacy - Planet Earth Online

    Global warming may dominate today’s environmental headlines but not so long ago it was acid rain. This emerged after the growth of industry and although the problem peaked in the late 1970s/early 80s and has largely gone away. But it has left a legacy in rivers and streams...
