QUICK GET THE ECO FOOTPRINT Compare the Total Ecological Footprint among countries. Which country has the lowest ecological footprint? Which country has the highest ecological footprint? French Guiana has the lowest ecological footprint. Nauru is the most energy deficit country. Compare the Ecological Footprint Per Person (i.e., “per capita”) among countries. Which country has the lowest per capita ecological footprint? Which country has the highest per capita ecological footprint? St. Martin has the lowest ecological footprint of 0. The highest country’s footprint is Nauru. Brainstorm three realistic strategies that you could take to reduce your footprint’s size. Use this list for possible solutions for reducing your ecological footprint. Three strategies I can use are buying organic food, not using transportation to go to school, and saving water. FISHING NEWWWW By what percent has the amount of tuna decreased globally since 1950? 50% decrease What was the original name of the Chilean sea bass? Why is this worth knowing? The Patagonian toothfish because they are a type of cod, not a bass. What is one proposed solution to overfishing at the individual, community, and national level? Government limits, banning harmful practices, establishing marine reserves, and raising consumer awareness and boycotts. Bottom Trawling - Has the largest impact on seafloor habitat destruction Midwater Trawls - Mouths of these nets can be as large as five football fields, Adding streamers to these gear types can scare away and reduce seabirds bycatch, Used to catch schooling fish Longlines - Adding streamers to these gear types can scare away and reduce seabirds bycatch, Used to catch large fish like tuna and swordfish using miles of baited hooks Purse Seines - Leads to significant accidental catch when used in conjunction with FADs(fish-aggravating-devices), Used to catch schooling fish Drift Nets - Adding pingers to these stationary nets can significantly reduce entanglement by sea turtles, marine mammals and sharks What are ITQ systems? What is one benefit, and what does the article suggest is a major drawback? ITQ systems allocate fishing quotas to individuals, allowing people to buy or sell quotas. It provides sustainable fishing by preventing overfishing. Although it is beneficial for fish, smaller fishers might lose access to the market because of high quota prices. What are two downsides of net pens? Net pens may cause pollution from fish wastes and uneaten feed, and increase risks of spreading diseases and parasites to fish populations. What species is usually farmed in man-made coastal ponds? What are two problems with this method of aquaculture? Shrimp are commonly farmed in man-made coastal ponds. Two problems are the destruction of coastal habitats like mangroves and water pollution from chemicals and waste. What are three benefits of shifting from the aquaculture of carnivorous fish to the regenerative ocean farming of seaweeds and shellfish? Regenerative ocean farming improves water quality, enhances biodiversity, and absorbs carbon, making it an eco-friendly alternative to carnivorous fish agriculture. Urban sprawl - people in cities leave until nobody is left and it is a suburban area. Why? People do this because it is cheaper housing, less taxes, better quality of life like less noise pollution. URBANIZATION- ​ Higher-density, people in urban areas do have agricultural jobs. ​ Using transit lowers fossil fuel usage and is efficient. ​ Being close to the city allows for walking and promotes good health. ​ More resource use because it is efficient. ​ More water is available, but upstream flooding, sediment issues, and decomposition problems arise in dams. ​ Downstream, there is no normal sediment needed for survival. SALTWATER INTRUSION- When taking more water than needed to recharge, the saltwater underneath intrudes into the well, contaminating the aquifer. We are only drawing up saltwater now, and we don't want to do this because removing salt is difficult. IMPERMEABLE SURFACES Groundwater does not recharge. More runoff goes to low-surface soil, polluting it because of contaminants. No water sinks in because there are no trees and no climate regulation. Impurities from cars and waste enter the atmosphere, causing carbon and methane emissions. This can lead to asthma, obesity, and depression. CITY STUFF ​ More car use leads to greater fossil fuel consumption. ​ There are more impermeable surfaces. ​ Heat is trapped in the city and suburbs. HOW TO SOLVE  ​ Add more trees to decrease runoff, address all problems, increase albedo, reduce heat, create carbon sinks, and purify environmental impacts. ​ Trees create air pockets for water to go through smoothly, also absorb it yum yum ​ Extend transit beyond the city by subsidizing public transport so more people will use it, which will lead to less fossil fuel usage. ​ Permeable pavement allows aquifers to recharge and decreases runoff. ​ Implement multi-use buildings, enhance city accessibility, and promote more biking and exercise. ​ Clean up brownfields by remediating abandoned buildings, reducing impermeable surfaces, and planting useful vegetation. GREEN REVOLUTION ​ Average food item only travel 2000 km from farm to home, transportation is 10% energy subsidy ​ 17% total commercial energy from growing, processing, transporting, cooking food, mostly food production at farm, food processing in factory + home ​ Started growing big big stuff, more growin w modern cultivation methods ​ Reliant on fert, irri, pest, more yields ​ Monocropping Green revolution ​ Shift from using mostly human labor and low fossil fuels to mainly machinery, fossil fuels, less people ​ Fertilization, irrigation, more crop varieties increase food production ​ First notion was with Norman Borlaug (1914-2009), created disease resistant and higher yielding wheat, increase agriculture with it ​ Mechanization, irrigation, use of fertilizer, monocropping, pesticide use Mechanization ​ Less than 5% of workforce works in agriculture, but in developing countries w/ lower wages, 40-75% ​ Using machinery is expensive, but more efficient when fossil fuels abundant, fuel prices are low, labor prices are high ​ Machinery is specialized, easy to use, more profits  ​ Big farms support big machinery because profit from big farm cover cost of machinery, but small farm can’t ​ Monocropping is good for machinery ​ But machinery makes more fossil fuels, more reliance upon machines Irrigation ​ 16% worlds agricultural land produces 40% of worlds food ​ It can be good, but depletes groundwater, aquifers, causes saltwater intrusion into freshwater wells ​ Waterlogging - soil degradation when soil is underwater long, impairs root growth bc no oxygen, no cellular respiration spec ​ Salinization - small salt in irrigation water concentrate on soil surface through evaporation, reaching toxic levels, impeding plant growth Fertilizers ​ Exporting crops removes organic matter + nutrients, so to replace depleting nutrients, use fertilizers ​ Organic and synthetic fertilizers ​ Organic - animal manure, crop residue decomposed to return nutrients, easy to use, contains more nutrients, adds organic matter so better structure like air pockets ​ Has to be gathered, nutrient levels are varying, harder to use, but cheap ​ Synthetic - artificially manufactured fertilizers, use of fossil fuels to create, easily absorbed by poor soils, overused, no help structure, kills benefical bacteria, reduces natural nutrients ​ Uses large amounts of fossil fuels, also carried by runoff into water, reducing oxygen, does not add organic matter to soil, some do add tho Monocropping ​ Corn, soybean, wheat, cotton, grown frequently ​ Efficient bc can be harvested and grown at the same time ​ Downside because loss of habitat and biodiversity, only one type of plant, increased the possibility of catastrophic event, one pest can kill everything ​ Soil erosion, wind can blow over bare soil, carries soil away, lose soil and lower productivity  ​ Pests that rely on crop plants reproduce quickly bc abundant food, predators also rise, but habitat loss bc no more plants ​ ​ Pesticides ​ Insecticides, herbicides, broad-spectrum pesticides, selective pesticide ​ Easily shipped, but can kill everything, but also contaminate groundwater ​ Insecticides - insect killers ​ Herbicides - kill plant species competing w crops ​ Broad-spectrum pesticides - kill many diff types of pest, can be selective or narrow-spectrum and target narrow range ​ Pesticides can kill more than needed, persistent pesticides like DDT kill bald eagles, more than needed, can build up toxicity ​ Use pesticides for yield, no damage crops, money ​ Pests might evolve resistance, so useless ​ Not reliable bc continue making new pesticides bc of resistant bugs ​ Can kill predatory insects eating crop pests, pollinators, plants fixing nitrogen and fertility ​ Runoff again w pesticides NOT EUTROPHICAN, just kill ​ Can get into drinking water, contaminated water ​ Carried by rain or wind, end up in residential and end up far awayyyy ​ GMO (last one) ​ Greater yield, less pesticide use, more profit ​ Inserting desirable DNA into plants to maximize yield ​ For example: bacteria creating its own toxins, this gene is taken out and put into corn, so pesticide-producing plants, getting rid of pests ​ Can spray weeds efficiently ​ Monocropping culture, limited genetic variety, can die from envior ​ Not good because it could unintentionally kill bees ​ Modified with new vitamins, creating bigger and better animals and produce ​ GMO reduces pesticide use, more money, more yield too ​ Genetically modified organisms very reliant ​ vulnerable to pests bc no genetic diversity, so bleh  ​ Less biodiversity, places that don’t accept GMOs, so have trouble transporting them, more reliance on buying GMO seeds, pesticide treadmill bc pests might have gained resistance to GMO pesticide production, more buying Why are GMOS bad ​ If gmos breed w their wild relatives, genes spread, no biodiversity and varieties ​ Contamination of wild plants and animals ​ Most seeds are controlled by big corps uh oh government ​ Dam the hype aint worth it banned in countries 😭 ​ Pesticide treadmill from pesticide-inducing plants Agricultural practices aughhhhhhhhhhhhhhh i cantttttttttttttttt ​ Tilling -
