What is a GMO?
Genetically Modified Organisms - Created by taking the DNA from one species and inserting it into another species
The benefit of using electric or hybrid vehicles
decrease in carbon dioxide emissions
BIGGEST concerns with GMOs
harmful to humans
longterm effects
potential allergies
Algal blooms are an overgrowth of microscopic algae or algae-like bacteria. They grow out of control and produce toxins that sicken or kill people and animals. In recent years, the South has seen an increase in algal blooms throughout the state. If the trends in the image continue how might public health be impacted?
A. less tourism to local beaches
B. more hospital visits within the community
C. fewer hospital visits within the community
Pollutants / Contaminants
The introduction of harmful materials into the environment
The benefit of farmers working with genetic engineers to create GMO papayas
increase the economy of Hawaii
reduced amount of papayas with the virus

Elephant
The downside of bioremediation as a way to clean polluted sites
the microbes take months or several years to clean the site
Plastics can take thousands of years to naturally break down in the environment. Scientists have discovered an enzyme (a special type of protein) that naturally breaks down plastic. If scientists were to genetically modify a bacteria to make this enzyme, what impact would the bacteria most likely have on the environment?
A. The bacteria could be used to clean up plastic pollution.
B. The bacteria would start destroying original wildlife and decrease biodiversity.
C. The bacteria would not be able to break down plastic in nature having no impact on the environment.
Bioremediation
The use of microorganisms/microbes to consume and break down environmental pollutants, in order to clean up a polluted site
The benefit of using bioremediation versus humans with cleaning a contamination site
less intrusive
less harsh chemicals
less financial cost
The reason we are uncertain about GMOs
they have only been around for a short amount of time / people are uncertain of the long-term risks
RANDOM QUESTION!!!!
The element Au on the periodic table
Gold
Biomagnification
the concentration of toxins in an organism as a result of its ingesting other plants or animals in which the toxins are more widely disbursed
OR
toxins moving up the food chain and increasing in intensity
Provide 2 benefits of using Genetically Modified crops
more nutrients
less disease
fewer pesticides
more food / growing faster
more desirable traits (less browning, etc)
medicines/vaccines
The risk associated with biomagnification
as pollution concentration increases, humans risk eating animals that have harmful chemicals inside them
Mosquitoes are one of the greatest killers of humans because they are able to pass on diseases. An idea scientists are testing to solve this problem is to infect mosquitoes with a naturally occurring bacteria called Wolbachia. Wolbachia spreads quickly. Once the mosquito is infected, the bacteria out-competes the virus or parasite that the mosquito would pass on to a human. What impact could Wolbachia have on human populations over time?
A. There would be no impact since Wolbachia cannot spread to an entire population.
B. More disease may be spread since the bacteria could mutate and infect humans.
C. Less disease may be spread since all members of a population will have the bacteria.
