Marine Ecosystems: Marine-Life Populations and Marine Life

marine ecosystems: For much of human history, we've affected marine ecosystems primarily by what we've taken out of the seas, according to Georgia Asian. The challenge as we encounter warming temperatures and increasing industrial activity will be to manage what we put into them. It's a fitting time to contemplate humanity's evolving relationship with the source of all life. As a top predator, humans from the tropics to the poles have harvested all forms of marine life, from the smallest shrimp to the largest whales, from the ocean's surface to its floor. Yet the ocean continues to provide food for billions of people, and improved fishing practices in many places, including Canada, are leading to healthier marine-life populations. The staggering volume of fish removed from our waters has had a ripple effect through all ocean ecosystems. (www.immigrantscanada.com). As reported in the news.
