to curb emissions was closing.<\/p>\n<p>&#8220;It&#8217;s the number one thing we need to think about now to save the reef,&#8221; he told the BBC.<\/p>\n<p>Improving fishing practices or water quality would not be enough, he said.<\/p>\n<p>httpv:\/\/www.youtube.com\/watch?v=8GQMhRqMtj4<\/p>\n<p>The reef &#8211;
