Commercial hunting was once the greatest threat to this species, but today, the biggest threat facing walruses is the loss of stable sea ice due to climate change. Walruses feed on the ocean floor in the relatively shallow waters of the continental shelf, where the sea ice sustains a rich food web. Sea ice is also a resting place for this species in between meals, and females will often leave their young on this frozen platform while they forage. Without the sea ice, walruses must swim longer distances to find food and a place to rest, which means burning through hard-earned energy stores that the walrus needs to survive. Warming conditions also mean more water vessels are able to venture into remote ecosystems that were once inaccessible, increasing the likelihood of boat strikes, water contamination, and entanglement in marine debris. By opting to walk, bike, carpool, or use public transport you reduce your transportation emissions which helps to slow the progression of global warming, protecting the homes of walruses and many other species. #walrus #pacificwalrus #bigtusks #climatechange #globalwarming #gogreen #greentransportation #PhotoArk #savetogether」8月14日 19時44分 - joelsartore
