Unit 5

Unregulated use of public resources will lead to depletion

a piece of rock or soil that contains groundwater, can be unconfined or confined

when groundwater is replenished by precipitation

drilling a hole into a confined aquifer

when groundwater is depleted because it is taken out faster than it can be replenished

when groundwater is not present to hold up the structure of coastal aquifers so saltwater rushes in

areas next to a river, extremely fertile

mounds that prevent water from flowing into areas

something that carries water to places

rows of water next to plants

is the most water efficient, drips water to roots of individual plants

flooding a field, results in the most salinization

when you flip over soil to loosen it up. Allows for more percolation of water, more nutrients, and reduced weeds

using means other than chemicals to get rid of pests such as natural predators, GMOs, and crop rotation

planting different crops each season to replenish the nutrients that are depleted in soil. Also helps to break up weeds

soil quality goes down, there are barely nutrients left and less of an opportunity for plants to flourish

things that are not calculated when you buy things

cutting all trees to their stumps

when water is unable to drain in a field

separates areas of land for different purposes: industry and residential

the amount of work in calories that goes into one calorie of food

a shift in agricultural practices (more mechanization and use of pesticides) which significantly increased the yield of crops

planting one type of plant over and over again - leads to depletion of nutrients in soil

a decline of at least 90% in fish populations
