Chapter 11 Vocabulary Relevancies 1. organic agriculture – The return to farming without pesticides; allows small farmers in core countries to compete with agribusiness. When fair trade laws are applied‚ organic farming in peripheral and semi-peripheral countries can bring wealth into a country by exporting to wealthier nations. 2. primary economic activity – most basic use of the natural environment to sustain human functions. Examples: hunting/gathering‚ farming‚ ranching‚ logging

Agriculture- the purposeful tending of crops and livestock in order to produce food and fiber Commercial Farming-the farming of products for sale off the farm and is most common in MDC’s Subsistence Farming-produce the food that they need to survive on a daily basis most common in LDC’s Hunting and Gathering – killing of wild game or collection of nuts‚ seeds‚ roots or plants that have not been cultivated for the purpose of sustenance First Agricultural Revolution - dating back 10‚000

the productivity of farm lands have also increased. The Green Revolution‚ The Industrial Revolution‚ and massive population growth all caused agriculture to change the ways that food was produced. Food production went from a very labor intensive profession to a mostly mechanised industry. Horses were replaced by tractors and farmers planted huge monoculture fields to produce more for sale‚ and less for the family. The yeoman farmer gradually faded out as the large scale industrial farmers became essential

be taken to improve the provision and consumption of sustainable foods. The three points that will be discussed regarding the environmental issue is the desalination plants that are being constructed around Australia‚ monoculture and the use of pesticides in growing foods. Monoculture is the practice of growing one crop continuously over one area and desalination is the removal of salt and other minerals from saline water. Paragraph 1- Desalination plants * The affects of the desalination plants
Premium Agriculture Sustainability Water
faster than the environment can absorb or recycle. Depletion of natural resources 1. Exhaustion of non-renewable resources: coal‚ oil‚ minerals 2. Overexploitation of renewable resources: fishery‚ forestry Destruction of natural environment Agriculture and urban development need clearance of lands – Destruction of scenery – Removal of vegetation cover • Hence‚ population control is needed to ensure a sustainable supply of natural resources and conservation of the environment. Types of resources
Premium Biodiversity Ecology Pollution
All these activities may have damaging environmental impacts. For example‚ land clearing for agriculture is the largest single cause of deforestation; chemical fertilisers and pesticides may contaminate water supplies; more intensive farming and the abandonment of fallow periods tend to exacerbate soil erosion; and the spread of monoculture and use of highyielding varieties of crops have been accompanied by the disappearance of old varieties of food plants which might have provided some insurance
Premium Agriculture Carbon dioxide Soil
The natural world is seemingly perfect‚ a multitude of entities exist that allow complex life forms to survive‚ while permitting various species to live alongside each other. The environment allows for biodiversity to take place; this factor allows for many forms of life to exist in harmony‚ also allowing for genetic variations of various species to survive. Since humans have been introduced into the environment‚ we have desired to maintain control of our surroundings by forcing nature to work for

crops containing herbicide tolerance transgenes‚ therefore conserves fertility through minimizing soil damage through compression. |GE agriculture claims low tillage weed control: this can be achieved by ending the practice of monoculture and instead introducing proper crop rotations designed specifically to combat the weeds of the particular locality. Monoculture creates a weed paradise. | All countries face problems caused by alien species accidentally or deliberately introduced into a new environment

Essay on The Importance of Degradation to the Environment "Jimmy‚ let’s see if you know the creatures of the rainforest. What sound does this one make?" "That’s right‚ a chainsaw goes RRRRRRRRR." A simple cartoon in a magazine‚ that’s all people see it as. There is constantly talk about the environment being destroyed and we’ve become immune to the topic. It just washes over us‚ without the idea actually sinking in. Everything that is being done on this planet somehow affects someone‚ something

chemicals for defense against predators‚ which then solved the problem of immobility. The practice of monoculture is also discussed in the book. Monoculture may be economically beneficial‚ but it can bring serious environmental risks. The growing of multiple varieties of a single crop increases the chance that if one fails‚ another will have the genetic traits that allow it to thrive. Monoculture also forces the identical plants to be vulnerable to pests and disease. The use of pesticides can be
