* Warm up * How overfishing affects productivity in marine food chains and food webs?

* Input question: * What do you know about overfishing?know

* Global overfishing is destroying ocean ecosystems. * Nearly one-third of marine fish stocks worldwide have been overfished, and over 90% of the world’s fisheries are fully exploited or over-fished, according a 2014 report by the United Nations Food and Agriculture Organization. * It's not just the fish we eat that are affected. * Each year, billions of unwanted fish and other animals - like dolphins, marine turtles, seabirds, sharks, and corals - die due to inefficient, illegal, and destructive fishing practices.

* Activity: - We will simulate fishing practices during the evolution of human society.
