```Introduction
 The Condor, is an important animal,
 People have damaged most of the condor
population.
 The condor population is in constant decay
 If the condor population keeps this constant
decay, will it get to the point of extintion?
The Condor
• Since 2000, the Condor
populations have declined,
• This is a endangered species
• There are only about 50-65
• causes for the decay of
Condors.
•
In 2009 an organization
dedicated to the protection of
the Condor was created.
• The Condor is a Monogamous
animal, and it can only lay one
egg a year.
 In 2002, Aves & Conservación stated that there were
no more than 70 individuals.
 The Andean Condor is considered a threat
 Condors, are scavengers, they only eat dead animals.
 The first condor census was made in 1991 and 200
condors were registered.
 The condor is the biggest flying land bird in the
world.

Goats info
 Feral goats are known
because of their big
appetite and because,
they eat everything
 They are devastating
for some sectors, and
in many plagues, they
are considered
plagues.
 Many people have to
search for a harsher
way of dealing with
them, for example
hunting, poisoning,
tracking, etc.
Math lab-Growth
 What is the exponential growth of Freral goats in
Galapagos
 Used initial and final number of goats in Pinta (3 in 1959
and 20,000 in 1971)
 Created a table with those values
 Approximated a growth factor (with calculator) for the 12
years (2.083)
 Filled the table by multiplying each value by the gf to get
the next value
 Used initial amount and gf to write the equation

Conclusion
As a conclusion we have realized
that if we continue growing
down this exponential decay
path , the condor could be
extinct in a few decades in fact in
five years from now there are
only going to be 36 condors
P=200(.715)= 36
This all means that by the year
2020 there could only be 36
