Organic farming provides not only an alternative safe and healthy farming model‚ but a way to correct the flaws in our current system. There are many benefits of organic foods and organic farming. Organic foods are free of harmful chemicals‚ artificial flavors‚ and preservatives. Conventional farmers use over 300 different pesticides to grow non-organic foods. The current process used in food production render little to no

Organic farming cannot feed the developing world It is argued that without pesticides and genetically modified crops‚ farming is not economically viable in the developing world. Non-organic farming allows you to farm land that would otherwise not be farmable. Yields are high and costs are low. However‚ there is a worry that intensive farming in these countries will destroy the fertility of the land and in the long run organic farming will secure the future for sustainable farming.

Experiment 9 : The effect of substrate concentration on enzyme activity Objective To find out the relationship between the substrate concentration and the rate of reaction by determining the number of bubbles produce Hydrogen peroxide (H2O2) is a by-product of biochemical metabolism. An accumulation of hydrogen peroxide can be deadly‚ so it has to be decomposed. One of the decomposing factors is an enzyme called Catalase. Catalase breaks hydrogen peroxide into water and oxygen. The chemical

March 1‚ 2013 Just Do Organic Many people are skeptical about organic food. It is told to them by their friends‚ and the media that organic food is better for the body and the environment. However‚ just because something is reiterated does not make it true; so many people ask‚ “Is organic food really better?” To this question comes the answer‚ yes‚ organic food is healthier for people and the environment than non-organic food. From produce to meats‚ food that isn’t organic is usually filled with

CHEM 3305 - 001 Organic Chemistry 1 Dr Michael Findlater Spring Semester‚ 2013 Stereochemistry • Stereochemistry refers to the three-dimensional structure of a molecule. • As a consequence of stereochemistry‚ apparently minor differences in 3D structure can result in vastly different properties. • We can observe this by considering starch and cellulose‚ which are both composed of the same repeating unit.

Marketplace Characteristics of U.S. Organic Sector The U.S. organic food industry crossed a threshold in 2000: for the first time‚ more organic food was purchased in conventional supermarkets than in any other venue. Industry estimates suggest that nearly half of the $7.8 billion spent on organic food in 2000 was purchased in conventional retail outlets. Organic products are now available in nearly 20‚000 natural foods stores (Natural Foods Merchandiser)‚ and are sold in 73 percent
