Our Green ICE Age Our Green ICE Age

TCS Daily: Our Green ICE Age points out that Internal Combustion Engines (ICE) are far better ecologically than the animals such engines replaced. Not only do livestock even now generate some 18% of all greenhouse gases (more than all ICE vehicles combined), but the horses, etc. that ICE replaced were huge polluters of towns, waterways, etc. One of the most significant ways in which city life was made healthier in the last 100 years was the replacement of horses by ICE vehicles.
