Bio
I was born in Upstate New York, across the street from where Mark Twain lies buried. My name belongs to my mother, who, having taken my father's last name upon their marriage, decided to give it to me to carry it on. My name is Grennan, and I am a freelance journalist and photographer.
I studied conservation biology and applied climate science in school, but after realizing I didn't have the constitution for lab work and statistics, switched my focus to the communications side of the field. Though I'll write on mostly anything falling within the umbrella of environmental science and nature, I tend to focus on environmental health, climate change, and wildlife conservation. My articles have appeared in Popular Science, VICE, GlacierHub, and Currently.
Aside from writing about invasive species or clean drinking water, I also like to watch soccer— Everton, Borussia Dortmund and New York City FC fan—play the drums, and run long distances.
I live in Brooklyn, NY.
The last word in ignorance is the man who says of an animal or plant: "What good is it?" If the land mechanism as a whole is good, then every part is good, whether we understand it or not. If the biota, in the course of aeons, has built something we like but do not understand,then who but a fool would discard seemingly useless parts? To keep every cog and wheel is the first precaution of intelligent tinkering.
