Due to animals consuming more grass than can be produce, the ground becomes scattered leaving the soil exposed to erosion. The NRCS (Natural Resources Conservation Services) has a program to help prevent overgrazing. The program “provides information and support to enable ranchers who own their lands to burn unwanted woody plants, reseed the land with perennial grass varieties that hold water, and manage cattle so that herds are moved to a new location before overgrazing occurs” (Wright & Boorse, 2011, p. 288). If this problem is left untreated, could be a threat to the food chain. Deforestation is when trees and other vegetation is being removed converting the forest to another land use, this exposed the soil and often leads to erosion and loss of soil fertility.
Laundry detergent hypothesis accept/reject = Reject// Laundry detergent also changed the viscosity of the water. What affects did each of the contaminants have on the water in the experiment? Which contaminant seemed to have the most potent effect on the water? Answer = From what I observed, oil is saturated into the soil leaving little to none of the water to pass through. While the vinegar passed through the soil leaving more dirty water.
Less than one percent of these animal products today come from family farms. C. Factory farming typically refers to cows, pigs, and chickens. D. So, in review, factory farming allows us to produce large amounts of animal products coming primarily from cows, pigs, and chickens cheaply. Factory farming, being the big industry that it is, must have some effects on the environment that need to be addressed. What are the environmental effects of factory farming?
Michael Pollan suggests how industrial food system is unsustainable because of monocultures, which means a lot of the same species are grown together and that’s only possible by using antibiotics to keep them alive. To keep crop healthy, fertilizer is needed. For example, in Iowa, all the farms were corn and soybeans, which are for industrial use mainly. Separating the animals from the farms raises a huge sanitation problem and the animals are not happy with the conditions, a pollution problem occurs as well. Society is obsessed with productivity becoming cheap, which has made more problems regarding pesticides.
Based on your data, which type of soil do you think is best for agriculture? Explain your answer. Loam would be the best kind of soil to plant crops in because it is permeable but it takes low amounts of water to irrigate the soil. Farmers often have problems with soil erosion when they clear their fields after the growing season. Soil type is one factor that influences erosion.
It is a soil microbe that was used to put foreign genes into plants and made it possible to improve crops. At this time, some animals were also starting to have their genes modified in a similar way. In the 1990s, people who knew about GM foods wanted it to be regulated. They argued that the food is changed and should be treated as a food additive so they should be regulated by the FDA (Food and Drug Administration). At this time, there are still a lot of things unknown about GMOs and how it affects humans and the environment and going organic is the best option right now.
There are many advantages and disadvantages both ecological and economical to buying locally versus buying from larger companies that manufacture their food from around the country and sometimes across the world. Buying locally made foods will give the most nutritional value due to food being at the peak of growth and not sent around and the country or around the world. Buying locally also helps the farmers to be able to get fair prices on their produce. According to Terrie Schultz, 2010 "Industrial agriculture is a major source of water pollution. Runoff of chemical fertilizers, animal waste and pesticides contaminates lakes and streams.
Clinical microbiology MLT1 Task 9 Antibiotic Sensitivity Chandra Evans A) Selectively Toxic is defined by the fact that the antimicrobial treatment used, destroys selective microorganisms, but doesn’t harm the host. Selective toxicity of an agent is necessary so that during treatment the agent will not affect or interact with the normal functioning microorganisms in the host. The agent will interact with microbial structures and functions that are not the same as the microbial structures of the host. B) Broad spectrum antimicrobials are effective against a large range of both Gram-negative and Gram-positive microorganisms A pro of this type of agent is the fact that a variety of bacteria is targeted at the same time when used. A con is the higher risk of destruction of normal body flora.
The sweet potato industry, although a high value industry, is becoming increasingly competitive. This underlines the importance of efficiency in minimising the loss of valuable soil. Large amounts of rainfall can result in the loss of soil on cultivated farmland. The loss of soil does not just affect the farmers it also affects the community The aim of the project was to increase awareness of soil health and to develop the best soil management practices for the Cudgen plateau. Figure [ 2 ] Water Way On the Cudgen Plateau, three adjoining landholders implemented soil conservation measures and strategies.
Science, Health, and Environmental Issues Pamela Ward Eng122: English Composition 2 Prof. Iris Chao October 27, 2013 Phosphates and Nitrates Phosphates and Nitrates are chemicals commonly found in water. Even though they are not harmful in small quantities, they are harmful if they exist in large quantities. Farms use fertilizers containing large amounts of nitrates and phosphates, so they can build up water near industrial-scale farms. In a body of water in which nitrate levels have risen to high levels, these chemicals can cause excessive algae growth. When the algae die and decompose, they deplete the available oxygen in the water for fish, causing them to die.
