I clearly did not meet any of the requirements for this day except for the fats.
c) My food consumption habits consist of mostly meats like beef and chicken and lack fruits and vegetables. I feel like I should consume vice versa, more fruits and vegetables and less meats. This would be beneficial for the environment because animals consume a lot more just to grow enough for us to eat. Instead of consuming less nutrients from them, I can consume the nutrients needed directly from eating fruits and vegetables.
5. a) I can tell that high intensity agricultural management is used in both Europe and North America because of the spikes within the patterns, which means they harvest a large amount at the same time, and the soil becomes damaged and produces less harvest, so they would need to wait until the soil is useable.
b) Changes in harvested area between 1990 - 2014
Africa: 1990: 60 million hectares 2014: increased to 120 million hectares +(100%)
North America: 1990: 80 million hectares 2014:decreased to 70 million hectares -(12.5%)
South America: 1990: 30 million hectares 2014: increased to 40 million …show more content…
An example of this situation is shown by the graphs of Europe.
6. This polyculture system was so sustainable because firstly, bean crops often host nitrogen fixing bacteria which allows for nitrogen to be readily used within the soil. Polycropping balances nutrient demands and also controls pests.
7. Widespread and continued use of a pesticide can increase the damage caused by a particular pest because the pesticide will kill off all of them except for the ones that are immune. The ones that are immune will reproduce and eventually none of them will be genetically resistant to the pesticide. Pesticides can kill off the target pests as well as the natural enemies, therefore creating new and dangerous pests by large numbers.
8. The argument between wild salmon and coastal salmon farmers in British Columbia is about fish farming having a negative impact on wild salmon. Wild salmon farmers are concerned about coastal salmon farmers because their mismanagement caused many wild juvenile salmon to die off. There is a need to get rid of open-net cages and to instead use one that ensures containment of the farmed fish and their
