Studying the animals’ tusks reveals that diet and exposure to pollution have shifted over the past half century in response to sea-ice decline. Human emissions have also led to a sharp rise in the presence of mercury in recent years, according to an international team of researchers.</p></div></div></div><div class="field field-name-field-primary-image field-type-image field-label-hidden"><div class="field-items"><div class="field-item even"><img class="no-float" src="/channels/files/channels/styles/wysiwyg_medium/public/channels/image/narwal_image.jpg?itok=kDw-s45t" width="160" height="107" alt="" /></div></div></div><div class="field field-name-field-published-date field-type-datestamp field-label-hidden"><div class="field-items"><div class="field-item even"><div class="custom-multi-date"><div class="multi-date first"><span class="label">Published: </span><span class="day">29 </span><span class="month">March </span><span class="year">2021</span></div></div></div></div></div> Mon, 29 Mar 2021 14:20:29 +0000 webfull 169475 at /channels
