causes of energy insecurity
fossil fuel depletion
climate change
population growth
renewable energy resources
hydroelectric dams, solar energy, wind energy
non-renewable energy resources
fossil fuels, nuclear energy using uranium as fuel
What effects population size
birth rate
death rate
immigration/emigration
Photosynthesis equation (words & symbols)
carbon dioxide + water _sunlight_ glucose+oxygen
6CO2+6H2O arrow C6H12O6+6O2
causes of water insecurity
-natural disasters
-pollution events
-international competition over water sources
air pollutant vs greehouse gases
air pollutant-lower air quality and decrease visibility
greenhouse gas-increass temperature
famine/malnutrition, forced migration, death
impacts of food insecurity
what is sustainability
the ability to meet the needs of the present without comprimising the ability of future generations to meet their own needs
list the layers of the earth
exosphere, stratosphere, thermosphere, troposphere, meososphere
impacts of energy security include
-increasing prices for energy resources
-job loss
-increased levels of poverty
-reliance on imported energy sources
impacts of water insecurity
-food shortage, famine
-crop growth failure
water shortages, poverty, population are casuse of…
food security
strategies to reduce water insecurity
-imporove irrigation
-growing less water dependent crops
-system to clean water and make it drinkable
-education on sustainable water use
-rain water catching
carbon equation
C6H12O6 +O6 arrow 6CO2+6H2O+ATP
strategies to reduce imapcts of waste disposal
-reduce, reuse, recycle
-comoposting
-use waste to feed animals or generate energy
air pollutnats
sulfur dioxide, ozone, lead, carbon monoxide
imporove transportation of food, agriculture techniques, reduce food waste
strategies to manage food security
impacts of human activity on tropical rainforest
agriculture expansion, climate change,mineral extraction
list steps of carbon cycle
respiration
feeding
decompostion
fossilisation
combustion
strategies to manage energy security
-increase energy production
-reduce reliance on fossil fuels
-invest in renewable resources
What is the International Union for Conservation of Nature (IUCN)
global inventory of the conservation status of animals, fungi, and plants around the world; role is to raise awareness, implement protection to conserve endangered species and support scientific research
List 3 pros and 3 cons of GM foods
Pros: less pesticides used, increased food supply, more nutrtious, longer shelf life, saves water, cheaper food prices
Cons: limit biodiversity (increased competiton between species), cause allegeric. reactions, antibotic resistance, foods not labeled that they include GM components
strategies to manage impacts of human activity on topical rainforest
legislation &national agreement, sustainable harvesting, create protected areas
factors that influenece data sampling
ease of access
size
knowledge of environment
