6.5 Fish & Meat production
Meat Production
Methods
Industrial
Happened due t green revolution= more feed / Antibiotics
Feedlots and Factory Farms
Higher yield
Grazing
Rangelands
Pastures
Human Health Risks
Hormones, Antibiotics, and antibiotic resistance
Environmental Damage
Water Consumption (irrigation, feeding livestock) and Pollution (waste goes into waterways
Overgrazing destroys the land
Large amounts of CO2 released from machinery / large energy costs and methane from cows contribute to climate change
Requires land for agriculture and more in order to feed the livestock and giving them a place to graze in
Leads to a rise in income in developing countries
Animal foods becoming cheaper
Fish Production
Methods
Fisheries
Concentration of aquatic species in a given ocean area or inland area of water.
Fish farms/Aquaculture
raising fish in freshwater ponds, lakes, reservoirs,rice paddies, or underwater cages.
3 billion people rely on fish production for protein
Environmental Damage
Fisheries
Seafloor trawling destroys countless habitats
Over-exploitation
Taken from ecosystems and therefore cause an unbalance in their former ecosystem
Many fish are contaminated with toxic heavy metals, PCBs and dioxins
Large CO2 production: fishing fleets use 12.5 units of energy to produce 1 unit of energy as seafood
Aquaculture
Some species produce large amounts of waste that lead to eutrophication
Important habitats are destroyed to make fish farms
Farmed fish can be contaminate by pesticides meant to kill water pest or leached from farm soils
More Sustainable Food Production
Don't have so many cattle in one area - avoids desertification since it means less mud/dust-pits
Ensure waste does not end up in rivers or lakes to avoid eutrophication
Spread feeding and watering areas out so they don't end up as mud pits (aka soil erosion)
Avoid feeding cattle antibiotics and growth hormones
