What is the difference between preservationists and conservationists?
Preservationists- more of a hands-off approach, pristine nature, do not use resources

What are the three main greenhouse gasses?
- Carbon
- Nitrous oxide
- Methane
What is the greenhouse effect and it is a positive or a negative thing?
some solar radiation is reflected by the atmosphere, but most is absorbed by the earth, which results in the earth warming up. It can be a good thing because it keeps earth at a viable temperature, but it does cause effects such as climate change, extreme weather, thawing of glacial ice, etc.

translocation
he blocked early efforts to stop captive breeding
he felt condors were too sensitive for anyone to mess with them and encouraged a hands-off approach
When was the last wild CA condor captured?
1987
When was the first captive bred condor hatched?
1988
When did the human population on earth reach one million?
Early 1800s
In addition to worsening the greenhouse effect, what other problem does excess carbon dioxide in the atmosphere cause?
ocean acidification
True or False: The great pacific garbage patch is only on the surface of the ocean
False. Plastic breaks down, it is underneath too
Among ocean pollutants, what is the primary source of mercury?

to get them away from the mosambi port where there is less protection and more gangs and poachers present
From the video on the condor’s shadow, name 4 reasons biologists may enter a condor’s nest:
- Check on/ replace eggs if they are not viable
- To do a blood draw and vaccinate against West Nile disease after 30 days
- Possible surgery for picking up and eating microtrash
- At 4 months they get a tracker
Name 3 causes of coastal habitat loss
- development of human presence and interference
- climate change leads to rising sea levels and storms
- pollution
When we first started releasing CA condors, what did we change to improve after the first ones did not behave in desirable ways?
- Artificial rearing with puppets to avoid human imprinting
- single reared with an adult made them less social
- released at a later age
