Sustainable

1st partial

environment, social, economy

main elements of sustainable development

make environment resilient

main goal of sustainable development

we're part of the environment (natural + artificial)

we should care about the environment because:

the ability to bounce back from impact

what is resilience

ecology

the study of both living factors and non-living factors and how they interact biotic (living) and abiotic (non-living)

biosphere, ecosystem, community, population

four levels of study of the ecology

- biosphere
- ecosystem
- community
- population

- bunch of ecosystem (the earth)
- different species and non living factors
- different species
- same kind of species

examples of abiotic factors

rocks, water, air, temperature

soil

\________ depends on if it has nutrients or organisms inside it to be either biotic factor or abiotic factor

limiting factors

factors that limits the population growth

types of limiting factors

density dependent and density independent

examples of density independent factors

catastrophes such as hurricanes, pollutants, and seasonal climate extremes

examples of density dependent factors

tend to worsen with more population for example diseases like covid

logistic growth

growth that we have when we reach the limit (carrying capacity)
continue to grow at the rate that the habitat allows

biodiversity

different species, diversity of life, ecosystem

three kinds of biodiversity

ecosystem, genetic, structural (different species)

keystone organism

organism that cannot be replaced because it plays an important role in the ecosystem

relationship between biodiversity and resilience

the more diverse, the more resilient

natural resources

the resources that we take from the nature in order to sustain life

two elements to take in account when we talk about natural resources

time (how long it takes to come back)
place (if it grows in other places)

types of natural resources

renewable, non-renewable, inexhaustible

classification of environmental impact

natural resources, pollution, land use

types of impacts

positive/negative, direct/indirect, accumulative, synergetic, residual, temporary/permanent, reversible/irreversible, continuous/periodic

indirect impact

the result of the direct effects

synergetic: combination of two or more different impacts that creates a new bigger impact
accumulative: the same impact piling up

difference between synergetic and accumulative impact

renewable + irreversible impact \= non-renewable impact

relationship between irreversible and renewable resources

prevention: before the problem
mitigation: after the problem

ways to prevent environmental impact

biodiversity is the safety net of the ecosystem

why is biodiversity important for human being
