What three-factor model is used for representing the impact on environment? What is a fourth factor that could be added to this? Give a simple explanation for each factor and describe what it means in terms of human impacts on the environment
Farmers use a variety of methods to protect their soils - Crop rotation can return nutrients to the soil and can be used as an alternative to letting fields lie fallow, which exposes soils to erosion. Contour farming protects soils against erosion by shaping agricultural fields to minimize the possibility of water running down a hillside.
The use of irrigation can prevent wind erosion, although used incorrectly it can cause water erosion and salinization. The final way to protect soils is by composting, returning vegetable wastes to cropland so that their fiber and minerals can promote humus development.
Explain the statement "the lower down in the food chain we eat, the greater percentage of solar energy we put to use, and the more people Earth can support" in terms of trophic levels and pyramids of energy. PART 1
This is because the second law of energy states that entropy increases as one goes from one level to the next and energy is lost as heat or light at each transfer. For this reason, people who rely heavily on meat as a source of food energy are less energy efficient than ones that rely on fewer animal products or a vegetarian diet. The biomass pyramid echoes this, as each trophic level contains less biomass (energy) than the lower level
They involve large-scale comparisons among groups of people, usually contrasting a group known to have been exposed to a toxicant with a group that has not. They allow for the risk of exposure to a toxicant to be determined. They are realistic, but a long time is required for the results of the studies to be determined. Furthermore, they do not address future effects of new products. Results of epidemiological studies must be interpreted cautiously because many factors affect health, and results do not determine cause and effect; they only measure statistical association.

Explain how climate change can affect agriculture and forestry. PART 2
Explain how climate change can affect agriculture and forestry. PART 3
The frequency and intensity of drought and forest fires could increase. Forest communities could in general move northward and upward in elevation as temperature and moisture levels change. Finally, both agricultural and forest systems may experience changes in pollinator populations which could affect the abundance and distribution of many plant species.

Declining death rates due to increased food production and improved medical care while birth rates remain high is characteristic of the ________ stage in the demographic transition model.
Which of the following factors drives TFR down?
Which of the following describes the relationship between population growth rates and population size.
falling growth rates automatically does not mean a smaller population, but that rates of increase are slowing
Which of the following is NOT a problem with using pesticides?
Which of the following best describes integrated pest management (IPM)?
