ENST 201 1st Edition Lecture 10Outline of Last Lecture I. Food Security over timeII. Concerns of Food SecurityIII. What can we do?Outline of Current Lecture I. More on GMO’sII. Urban AgricultureIII. Labor Intensive AgricultureCurrent LectureI. More on GMO’sa. There are many arguments against the use of GMO’si. GMO genes will contaminate the natural gene pool1. Ex. In optimal conditions, farm raised salmon will outcompete wild salmon, which may push out the wild salmon populationii. GMO’s can lead to the creation of super weeds iii. Opposition is also there because of the lack of strict government regulations on GMO’s1. Ex. Genetically modified starch that did not pass to be safe for humans, but somehow it got into some products that circulated through the country (luckily it did not harm anyone)iv. Fear of long term damage that has not been seen yetv. Ethical problems with creating new life forms and patenting themII. Urban Agriculturea. Agriculture moving into urban areasb. Crops are being grown in skyscrapers to conserve space and to grow more crops in one areac. Waste that was shipped to rural areas to be recycled can now be recycled in urban areas to water the cropsi. Running out of phosphates, which plants need, so recycling waste water provides plants which that necessityIII. Labor Intensive AgricultureThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.a. Can be seen as a backwards way of thinking, because it pushes people to move toward rural areas instead of to urban areasb. Beneficial because urban areas cannot support a large influx of people from ruralareas with jobs and spacec. Wet Rice: provides a lot of jobs because it is so labor intensivei. Production is marginal so with more people working there is more yield1. Not decreasing the “pie slice” by adding more peopleii. Farmers grow rice in wetlands, so they can also grow fish and add amphibians and water fowl to their rice paddies1. Proximity of humans to the water fowl increases chance of diseased. Vietnami. Urban population is about 20% and rural population is about 80%1. Government is trying to slow down the migration from rural to urban areas by increasing the standard of living ii. Soils in Vietnam are very high in sulfur which is bad for plants, so farmers have to build mounds to plant crops iii. Instead of cutting down trees or branches and drying them to burn, they use pigs1. Methan collection tanks were installed where pig waste went to the waters and pipes collected the methane which was stored in
