EESA01H3 Lecture Notes - Lecture 10: Fish Farming, Ecosystem Diversity, Organic Food
Document Summary
More farmed fish nowadays: good for food security, prevent overharvesting. 90% of the fish people eat is ocean fish rather than freshwaeter. Aquaculture atnks are overcrowded more fish than water (exaggeration) Most atlantic salmon is farmed or wild salmon. Most salmon is pumped with red food colouring and is actually raised in fish farm. Organic foods have no synthetic fertilizer or pesticide. Most advantageous food to buy organic is peach as they are scrumptious to pests" so need more pesticides. Around 1% of globally farmed land is organic. A food where you don"t have much of a choice of it being organic is salad mix (almost always organic) Organic food is uglier because other foods are fakely made pretty. Why is organic more expensive if you don"t use pesticides and other chemicals: less crop per yield, more susceptible to have a huge pest infestation b/c your not using pesticides and things.
