  1. the environmental resources

  2. Non-renewable mineral resources are limited and finite.

  3. Non renewable carbon fuels - coal, natural gas, petroleum - are limited and finite.

  4. Water has a cycle and is not renewable and is limited.

  5. Heat and light from the sun and wind are forms of solar energy.

  6. All renewables resources are derived from life sources.

  1. biodiversity

  2. Life is variety-biodiversity. This diversity is essential for natural balance and for the survival of all life.

  1. photosynthesis

  2. Life depends directly or indirectly on photosynthesis performed only by plants.

  1. natural cycles

  2. Life follows its mission and is cyclical, as are various natural cycles which know no national or political boundaries.

  1. life

  2. Life’s only mission is to sustain itself. This is done by metabolism - the chemical process that happens within a living organism in order to maintain life-  and by reproduction.

  3. Only life is biodegradable.

  1. we, humans

  2. All life (except human) uses resources from the environment, burns energy (fuel) and generates waste (bio degradable) - limited by the need to grow to maturity and to reproduce.

  3. We humans exploit the environment and use external energy (fuels) and create waste (pollution) - beyond our needs, making us different and a problem for life on Earth.

  4. See impact of humans below.

ideas for action

ideas for action
soil erosion; soil & water degradation
climate change
warming of oceans
loss of glaciers
melting of arctic ocean ice & reduction in reflection of sunlight
ocean acidification
demand on fresh water
changes in land use & human habitation
oceanic dead zones
conflicts for diminishing resources
emission of green house gases-carbon dioxide, methane & nitrous oxide
nitrogen &   phosphorus run offs
soot (burning of biomass) & sulfates
release of mercury & other chemicals to the environment
burning of carbon fuels- biomass
exploding population
nitrogen & phosphorus cycles
domestication of animals for meat and labor
industrial meat production & consumption
production of chemicals for commercial use
warmer winter & summer temperatures
soot (burning of biomass)
nitrogen fertilizers
large scale monoculture agriculture & cattle raising

  1. effects

  1. effects

  1. consequences

aerosol atmospheric loading
agriculture-natural / organic
water shortages
rise in sea level; threat  to  coastal populations
upset of regional ecosystems & loss of biodiversity
loss of marine life including fish- a food source.
more loss of bio diversity
poor crop yields & food shortages
  1. the sun

  2. Our Sun and its energy is the basis of life on Earth.

  1. water

  2. We are a water planet. Life depends on water.

  1. soil

  2. Life on land, including human, depends on the quality of top soil which is limited and finite. Soil is a living entity.

some basics

loss of biodiversity
carbon dioxide emissions
depletion of aquifirs
poor crop yields & food shortages
water shortage
increase in meat consumption
loss of grtains for human food
food shortage
malnutrition, hunger & migration
soil erosion & salinization of irrigated soil
disruption to earth’s radiation patterns
energy intensive industry, technologies, transportation
increase in non -biodegradable waste & pollution
more landfills & trash in the ocean
peak oil and resource depletion
contamination of ocean & freshwater fish
poisoned marine life &  food sources
need based economy
loss of marine life including fish- a food source.
large scale soil erosion & salinization of irrigated soil low levels of organic matter
wars. conflicts
loss of top soil

human impact

1769 AD
  1. 20th century

  1. post industrial revolution

economy based on unlimited growth, consumption & waste
hunger  & malnutrition
food waste
wars & conflicts
  1. early 21st  century

  1. The year James Watt patented his steam engine used for pumping water from coal mines. Generally considered the beginning of the Industrial Revolution.

intense and widespread use of carbon fuels-coal, oil and natural gas
  1. What will unfold - a sustainable future or a collapse - will depend on what the human species - you and I - decide to do now.
