-Much land is deforested and disrupted as diamond and silver mining emerges. -New crops from Americas causes India’s population to rise almost double in size. -Columbian Exchange brings new crops to this region‚ allowing for the farmers of the region to exploit more of their land for extra crops. -American crops such as potatoes and corn increases population of the region. -Traders of the region utilize the monsoon winds in order to navigate across the Indian Ocean. -Silver mining causes deforestation

traits such as plants that have much higher nutritional content than traditional varieties (Turk and Bensel‚ 2011). Unlike the first green revolution‚ which was achieved mainly through traditional plant-breeding approaches‚ genetic modification of crops represents a fundamentally new technology. Traditional plant breeding sought to cross-breed or combine traits from the same plant types to produce a new and better variety (Turk and Bensel‚ 2011). In contrast‚ genetic modification works by removing

significant amount of soil loss each year in Ontario. Soil erosion may be a slow process that continues relatively unnoticed‚ or it may occur at an alarming rate causing serious loss of topsoil. The loss of soil from farmland may be reflected in reduced crop production potential‚ lower surface water quality and damaged drainage networks. Erosion by Water The rate and magnitude of soil erosion by water is controlled by the following factors: Rainfall Intensity and Runoff Both rainfall and runoff

1) Intensive farming practices include growing high-yield crops‚ using fertilisers and pesticides and keeping animals indoors. Food production is increased but there are unwelcome side effects. 2) Prevents energy being transferred from the crop to consumers. Reduces biodiversity. May poison helpful organisms. 3) Chemical insecticides (which kill insect pests). Herbicides which kill plants or weeds. 4) Ground water contamination: Chemicals can reach underground aquifers if there is persistent

another‚ to combine the desired traits of both‚ and the results are called “cross-breeds”. Plant breeders cross one type of plant that may be high yielding but not drought tolerant with another that is drought resistant but doesn’t produce a large crop‚ to create a “hybrid” plant that offers both desired qualities in one. In 1953‚ two scientists‚ James Watson and Francis Crick‚ discovered the structure of DNA. Twenty years later‚ Stanley Cohen and Herbert Boyer developed the first recombinant

The potato’s introduction into Europe proves to be one of the most significant examples of a foreign food crop being able to extensively affect the lives of a an Old World Population. Before the assimilation of the potato crop into the majority of Europe’s agricultural landscape‚ peasant populations constantly faced famines while current food sources provided little nutritional value and were not efficient sources of energy. As Europe adopted the brown tuber‚ people were provided with a far more

Genetically modified foods use the latest molecular biology techniques and are commonly used for growing crops for human or animal consumption. GM foods can create specific characteristics of plants or animals‚ such as the ably to withstand weather conditions(temperature)‚ nutrition and they can keep food for a longer time period- for example‚ A genetically

Hungry World For hundreds of years‚ humans have selectively bred and crossbred animals and plants to create or eliminate specific characteristics to produce a wider range of crops‚ animals and livestock. Genetic technology has become very common in our world today. Therefore‚ the possibility of altering plants and specifically crops for food supply raises many ethical and possible health issues which need to be explored. For example‚ the technical aspects of genetic modification and the possible positive
