According to climatologist James Lovelock, Earth's greatest enemies destabilizing the planet's climate are cows, cars, and chainsaws. Cows, cars, and chainsaws all contribute to increasing greenhouse gases in the atmosphere such as methane and carbon dioxide, warming the climate.

Climatologist James Lovelock (

(originator of the
Gaia_hypothesis
) once said that Earth's greatest enemies were the Three C's:
cars, cows and chainsaws because of their contributions to
destabilizing planetary climate.
A. In this final Discussion Forum, you will answer the
following question to show your ability to find connections
among the environmental issues that you have learned about in
this course.
Number your responses so I can see you have addressed each
part.
You must cite specific evidence from any Unit of the course to
support each of your responses.
Each contributing factor is worth 4 points x 3 = 12 points.
1.
What
and
how
do
each
of these things contribute to the destabilizing of Earth's

2. atmosphere
and
its climate?
1a. cows?
1b. cars?
1c. chainsaws?
Reminders:
Loss of land plants because of human activities will
not
result in a reduction of atmospheric oxygen because most of
planetary photosynthesis and its resulting oxygen production is
in the oceans.
