What are the 5 causes of air pollution?
Acid rain is caused by 2 molecules originated by fossil fuels.
What are sulfur dioxide (SO2), Nitrogen Dioxide (NO2)?
Industrial waste, mining activity (arsenic, lead and cadmium), sewage and garbage, pesticides and fertilizers, acid , leakage of radioactivity and mismanaged nuclear waste.
What are causes of land and soil pollution?
Industrial waste, sewage, and garbage, agricultural runoff of pesticides and fertilizers, soil erosion, weathering leading to sediment pollution.
What are causes of water pollution?
Sediment, change in temperature or dissolved oxygen (DO).
What is physical pollution?
28% of industry (coal power plants) and 24% of (manufacturing)=52% More than half.
What percent power plants & manufacturing produce pollution?
Other pollutant molecules besides SO2 and NO2.
What are carbon dioxide (CO2), carbon monoxide (CO), ozone (O3), lead, smog, dust, particulate matter (particle pollution)?
Toxic crops.
What are the effects of infertile land?
Thousands of sea otters, seals, whales, and dolphins, sea turtles, salmon and herring eggs killed.
What are oil spills from tanker or oil wells?
Fishing net/lines, plastic bottles, plastic bags.
What is solid waste?
27% of gas-burning cars, trucks, planes.
What percent transportation causes pollution?
Increased burning of fossil fuels leads to greenhouse gas emissions especially (CO2) causing increased global warming and climate change.
What are the effects of air pollution on climate?
Explosion in the Chernobyl Nuclear Power plant in Ukraine in 1986-worst nuclear power plant disaster in history. Lead to thousands of deaths from worker in the plant. This caused cancer in people.
What is an example of Radioactivity given to people from a nuclear power plant?
Heated water released from power plants.
What is water pollution?
Toxic metals (lead or mercury), acids (ph), bases, pesticides, fertilizers, paint, chlorine from pools, salinity affects fresh water ecosystems, plastics, hydrocarbons (oil spills).
What is chemical pollution?
10% of what causes air pollution?
What percent of agriculture causes air pollution?
Asthma and cancer.
What health problems occur from pollution.
Cancer
What does radioactivity cause?
One million shore birds.
What did the Exxon Valdes oil disaster in Alaska kill?
Goldlilocks effects for temperature, pH (acidity), salinity, DO aquatic and marine organisms usually have an optimal range for survival-outside the zone.
What is zone of stress?
8% of this causes air pollution?
What are commercial products?
Acid rain causes destruction of lakes , streams, rivers, oceans and kills many organisms and decreases biodiversity by making the water more acidic (lower ph)
What causes pollution of biodiversity?
Transportation and industry cause this type of pollution?
What is noise pollution?

It is a chain reaction, caused by too many nutrients added to water, leading to excessive plant and algae growth or algal bloom-->these plants die/decompose, using up oxygen-->reduces DO-->the result of decreased oxygen in the water kills fish, other aquatic and marine organisms, reduces biodiversity.
What is eutrophication?
