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

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

3. * 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.

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

8. * What is happening in our days?

9. * Poor fisheries management * Pirate fishers that don’t respect fishing laws or agreements * Massive bycatch of juvenile fish and other marine species * Subsidies that keep too many boats on the water * Unfair Fisheries Partnership Agreements that allow foreign fleets to overfish in the waters of developing countries * Destructive fishing practices
