Also watch the Food Inc. trailer.... it's all about corn's scheme for world domination.
Go to a farmer's market or a store and watch people's food habits. Observe and write them down in a small notebook. In other words, collect some data. Now let's think about our diet and what we are eating in this process. Is agriculture a co-evolutionary development? Think about this one from the perspective of dogs. Name something else that we are competing with. And analyze our relationship with other species points of view. How could we test this?
Explanation / Answer
The basic theme in this question is of that : nowdays is agriculture a co-evolutionary development ? the answer is yes . Anthropogenic impacts are widely driving ecological & evolutionary process the need to use a proportion of land ,which involves the process for intensive producton of crops,with reducing enviornmental impacts.the main aim is the transformation to genetic technologies & the changes in the use of land.the use of evolutionary principles ie crop breeding,cattle breedimg, domestication of animals ,knowledge & selection for pest resistance.lands are being used for the production of land scapes wich benefit the humans in other ways
Developments impact on all aspects in simplification of natural ecosystem , global breeding of species & changes in the use of land for inovative crops.Species interactions are being carried out through traditional programmes & introducing genes into crops through genetic modification (GM).
Agriculture is also impacted byclimatic variability & the requirement to increase food & bio-energy feed stock production. the introduction & use of new pathogens , pest genotypes & the evolution ofresistant pesticide, has controlled the distrupting natural processin agro-ecosystem.
Here we can just figure out evolution through human & natural selection in a) agriculture species b) pest & weeds c) bio control agents d) diease control e) wild & natural species.
IT is being thought that food security is becomining a universal concern for mankind datas indicate more food is required & the demand has to be met ,so increasing yields with existing agricultural land has to be created many factors such urbanisation,conservation & bio energy feed stock production. MAINLY WATER is becomming a limited factor in many agricultural regions, input tncreasing costs govt pressure to to increase resourse use effiencies .not for the economic perspective ,but for reducing enviornmental impacts.The introduction of new non food ,crops & pest, weeds & dieases control stratgies .Finally all these factors provide opportunities for ecological & evolution changes in agro -ecosystem.
