Do you believe humans have overextended our abilities to live in balance with Earth's ecosystems?

Yes

Explanation:

Humans have many abilities, Ted Nordhaus, co-founder of the Breakthrough Institute, a California-based energy and environment think tank, seeks to enlist readers in his optimistic vision of the future. It’s a future in which there are many more people on the planet and each enjoys a high standard of living, while environmental impacts are reduced. It’s a cheery vision. Some people just, cross the line :) Hope this was helpful!
