meet the needs of present generation without compromising the ability of future generations to meet their needs

environmental, economics, society

• Loss of Wildlife (hippo, antelope, shrew, hedgehog
• Cultivate marginal alnds (hard on landscape)
• Deforestation (less to plant)
• Saltation and soil depletion(loss top soil, silt runs into water body fills with dirt, lose topsoil)

Population density/growth(overuse of resources, use more land run inot problems with wildlife,environmental stress)

population growth, land use, environmental stress, overuse of resources

• overpopulation (population growth interaction with consumption)
• resource use

rate and scale population growth interaction with consumption

take waht benefits you can

• birth/death rates
• fertility
• culture/religion
• economics
• politics 

bottom line why you do something (survival, pass on genes and survive)

immediate cues that you choose to do

selective pressures to consume have created such a strong desire tod o so for reproductive measures

a measure of how much biologically productive land and and water and individual/population requires to produce the resources necessary and abosrb its wastes given previaling technology

the capacity of a biologically productive area to generate renewable resources and abosrb its waste

the millions of plants, animals, and microorganisms, the genes they contain and teh intricate ecosystems they help build inot the living environment

species, community, genetic 

alpha, beta, gamma

how many different species are in that area/community

how many spcies are there, individual species

how the species are distributed in environment

measures diversity across habitats look at change in species diversity across communites

diversity across really large landscapes

species that live in a particular locationa dn their interation 

biological community and/plus the physical and chemical environment, exsists within biological community

number of indivuals and/or species that an environment can hold

take and harvest energy from sun

eat the primary producers (leaves, grass, etc)

eat primary or secondary consumers (predators/carnivores)

eat everything

eat decaying organic materials

feed off everything/every level

species that have an unusually larger effect on the ecosystem than we would predict based on biomass/abundance

all processes are funtioning normally

ecosystem is able to remian in the same state, need to conserve species and processes of that community

the ability of ecosystem or community to maintain state on face of disturbance

the ability to bounce back after a disturbance

rainforest, coral reefs, deep sea, large tropical lakes, other key habitats (mangroves, wetlands, grasslands)

habitat loss/destruction, habitat change, overharvesting, pollution, climate change, habitat fragmentation

increase in concentration of a pollutant from the environment to teh first organism in food chain

increase in concentraion of a pollutant from one link in a food chian to another

greatest amount of resource that can be harvested each year and replaced through population growth 

areas wth high biodiversity and endemism (species found nowhere else) that face exceptional threat of imminent habitat destruction
