Hope Jahren said this quote

“ The leaves of the world comprise countless billion elaborations of a single, simple machine designed for one job only – a job upon which hinges humankind. Leaves make sugar. Plants are the only things in the universe that can make sugar out of nonliving inorganic matter. All the sugar that you have ever eaten was first made within a leaf. Without a constant supply of glucose to your brain, you will die. Period. Under duress, your liver can make glucose out of protein or fat – but that protein or fat was originally constructed from a plant sugar within some other animal. It’s inescapable: at this very moment, within the synapses of your brain, leaves are fueling thoughts of leaves. ”

Hope Jahren Acceptance Knowledge

People will tell you that you have to know math to be a scientist, or physics or chemistry. They're wrong. ... What comes first is a question, and you're already there. It's not nearly as involved as people make it out to be.

Hope Jahren Science

You may have heard that America doesn't have enough scientists and is in danger of falling behind (whatever that means) because of it. Tell this to an academic scientist and watch her laugh. For the last thirty years, the amount of the U.S. annual budget that goes to non-defense related research has been frozen. From a purely budgetary perspective, we don't have too few scientists, we've got far too many, and we keep graduating more each year. America may say that it values science, but it sure as hell doesn't want to pay for it. Within environmental science in particular, we see the crippling effects that come from having been resource-hobbled for decades: degrading farmland, species extinction, progressive deforestation... The list goes on and on.

Our world is falling apart quietly. Human civilization has reduced the plant, a four-million-year-old life form, into three things: food, medicine, and wood. In our relentless and ever-intensifying obsession with obtaining a higher volume, potency, and variety of these three things, we have devastated plant ecology to an extent that millions of years of natural disaster could not. Roads have grow like a manic fungus and the endless miles of ditches that bracket these roads serve as hasty graves for perhaps millions of plant species extinguished in the name of progress. Planet Earth is nearly a Dr. Seuss book made real: every year since 1990 we have created more than eight billion new stumps. If we continue to fell healthy trees at this rate, less then six hundred years from now, every tree on the planet will have been reduced to a stump. My job is about making sure there will be some evidence that someone cared about the great tragedy that unfolded during our age.
