The giant sequoias are nature's examples of real productivity and efficiency. They can be viewed as solar powered hydraulic fire resistant pumps that transmit about 500 gallons of water each day up their ~ 300+ feet trunks and efficiently reuse during warmer temperatures. Some of the oldest sequoias have done this for over 3,000 years - Sequoias were already 800 years alive when Christ was born. Humans are expendable for plant species. Hubris would lead us to believe vice versa.
Climate imbalances could result in insufficient groundwater to help these trees endure longer and warmer summers in the future.
“The system of nature, of which man is a part, tends to be self-balancing, self-adjusting, self-cleansing. Not so with technology."
