3b describing ways in which humans can modify ecosystems and describe and predict the
potential impact (e.g. human population growth; technology; destruction of habitats;
agriculture; pollution; and atmospheric changes).

and describe and predict the potential effects.
Looking at the website on Global warming in class, I want you to answer the
following questions. All of the answers can be found on the website video
by watching the signs, sources, and carbon cycle tabs on the site
http://dsc.discovery.com/convergence/globalwarming/globalwarming.html
Questions- YOU MUST ANSWER ALL OF THE QUESTIONS
Carbon cycle
1) How did humans release millions of years of carbon locked in oil into
today’s atmosphere?
2) Carbon compounds are responsible for trapping heat in the biosphere. Are
all of these following greenhouse gasses below carbon compounds? Identify
and underline them.
Methane (CH4), Carbon monoxide (CO), Carbon dioxide (CO2), Nitrogen
oxide (N2O)
3) How can you reduce your “carbon” footprint as stated in the Carbon cycle
section of the video?
4) What is the best way to get the excess carbon (CO2, CH4 ) gasses out of
the atmosphere?
5) How are plants and algae involved with carbon sequestration?
6) List and explain three sources of global warming. Show how these
sources can cause global warming.
7) What are the signs of global warming? List and give a brief description of
each sign.
8) Describe and identify how some new human technologies can lessen some
environmental problems that affect our world?
9 +10) Review question: Go back to your notes in class and answer the
following questionWhy would it be good for some politicians if we didn’t believe in Global
warming? Please use supportive evidence in your answer.
