In other words, fuel costs for electric vehicles kick the pants off of internal combustion engine vehicles (same goes for maintenance costs, by the way).

Dr. Hayhoe understands how important it is to walk the line between knowing the science of climate change and articulating a positive vision for the future, and she does that well. As she said in her TED Talk, “What we need to fix this thing is rational hope.”

In a nutshell, the circular economy is about keeping materials where they have the greatest value in the flow of commerce, thereby limiting extraction of virgin materials and disposal of items in waste streams.

Strong triple bottom line companies seek to operate in a way that creates value in all three realms simultaneously. It’s about more of all, not some of each, and it requires a business to be honest about the harms it inflicts and authentic in seeking to eliminate those harms."

The thing I did was write a book. Well, the second half of a book to be more precise. My grandfather wrote the first half, which he and Interface released as Mid-Course Correction in 1998.
