Greenhouse gasses
CO₂ , O₃ , CH₄ , SO₂ , CFCs , H₂O (water) vapor
Increasing the amount of nitrogen and phosphorus leads to
more algae growth
What results from eutrophication?
Bacteria decompose the dead algae using the oxygen in the water. The decrease in oxygen causes a decline in the biodiversity in the aquatic ecosystem.
What are some sources of nutrient pollutions?
Farms, city streets, pet waste, lawn fertilizer, faulty septic systems, and sewage treatment plan
What are some negative impacts of eutrophication?
Bad water odor, unsafe water conditions, decline in fishing, and it is expensive to clean up contaminated areas
As carbon dioxide concentrations increase,
temperatures increase
What are some impacts of global climate change?
Glacier recession, rising sea levels, increase in spread of disease
What are some affects of carbonic acid?
Marine organisms growing smaller in size Disruption in the aquatic food web due to species dying off Ocean water becoming more acidic Food shortenings for humans increase along coastal areas
Biodiversity
The variety of organisms in an ecosystem
Biodiversity helps
stabilize the ecosystem
Keystone Species
A single species that is vital to ecosystem stability
What are some examples of keystone species?
Otters, American alligators, sharks, and more
Invasive Species
Non-native species that spread rapidly across large areas
Why are invasive species such a threat?
They outcompete native species, have a high reproductive rate, and have no predators
H.I.P.P.O
Habitat loss, Invasive Species, Pollution, (human) Population, Overharvesting
Non-Renewable Resources
Resources with a fixed amount (finite)
Examples of non-renewable resources
Gold, soil, sand, phosphate, fossil fuels, uranium
What are the pros of non-renewable resources?
They are easy access and cheap
What are the cons of non-renewable resources?
There is a limited supply
It releases air pollutants
Connected to global warming and climate change
Degrades land from extraction of resource
Renewable Resources
Resources that can replenish themselves over time
What are some examples of renewable resources?
Wind, sunlight, plants, water
What are the pros of renewable resources?
Infinite
Reliable
Low to no air pollution
Less reliance on foreign sources
What are the cons of renewable resources?
It is expensive (costly) and has geographic limitations (unless you are near a body of water, you cannot use hydroelectric energy, etc.)
Ocean Acidification
Oceans become more acidic and start harming marine organisms by dissolving their shells, slowing their digestion, making them smaller/weaker, etc.
Which organisms in the ocean are the first to be affected by ocean acidification?
Aquatic animals with shells, crabs for example
Global Warming
the increase of global surface temperatures
Climate Change
Long term effects of global warming
Pollution
Any chemical, gas, microorganism, or solid material (plastic) found in air and water that harms other organisms
Air Pollution - Acid Rain
Pollutants in the air (SO₂ and NOx) from burning fossil fuels and water vapor = acid rain, nitrates + sulfuric dioxide = acid rain
Acid rain lowers
the pH of the soil and water, which causes a loss in biodiversity
Point Source
A single, identifiable discharge point
Non-point Source
No single, identifiable discharge point, is very costly to clean up, specifically aquatic environments
Examples of non-point sources are
Sediments from construction or agriculture Run-off of oil and plastic
Troposphere
Lowest atmosphere level, where we live
Stratosphere
Contains ozone O₃ that filters out harmful UV from entering troposphere, must protect
Ozone Depletion
Thinning of ozone layer as result of the release of manmade chemicals called CFCs
Where is the ozone layer located?
Stratosphere
Eutrophication
When the concentration of nutrients in any body of water keeps increasing
Eutrophication creates
dead zones
The excess nutrients contaminating a body of water cause
Nutrient Pollution
List some things people do daily that effect CO2 going into the air
Driving your car, using a lawn mower, using fertilizer, using a gas stove, etc
What is the primary cause of ozone depletion?
CFCs are the primary cause
Which layer has smog and other gunk?
Troposphere
Consequences of Global Climate Change
Rising sea levels
Loss of biodiversity
Unpredictable weather events (floods & storms)
Increase in diseases
Global food and water shortages
