Question

Climatologist James Lovelock (http://www.jameslovelock.org/) (originator of the Gaia_hypothesis ) once said that Earth's greatest enemies were cars, cows and chainsaws because of their contributions to destabilizing planetary climate. In this final Discussion Forum, you will answer the following two (2) questions that show your ability to find connections between the environmental issues that you have learned about in this course. 1. How do each of these things (cars, cows, and chainsaws) contribute to the destabilizing of Earth's atmosphere and climate? You must cite specific evidence from any Unit of the course to support your response. 2. How are these three things connected to one another either by cause, effect or by solution. Consider all of the environmental concerns you have been learning about during the entire course and describe how these 3Cs as a group relate to one specific environmental issue (other than atmospheric destabilization). Reminder: Loss of land plants will not result in a reduction of atmospheric oxygen (because most of planetary photosynthesis and its resulting oxygen production is in the oceans). Be sure to back up your explanations with some research before discussing this topic online with your classmates. Be sure to read relevant sections of your text (and supplementary readings from this Module) and look online.

Explanation / Answer

1. Cars, cows and chainsaw support destabilization of earth atmosphere by contributing to carbon foot prints which leads to global warming and finally to climate change in earth.

2. When plants are cut apart form oxygen depletion, it also cools atmosphere which allows rain fall, Red meet produces major carbon emission more than cars says experts. Cars are reported to emit more carbon which alters earths atmosphere.
