“A carbon footprint is the amount of greenhouse gases that you are responsible for putting into the atmosphere, and by ‘greenhouse gas,’ I mean mainly carbon dioxide,” Bostick said. “The main effect on the Earth is global warming, or atmospheric warming. It’s somewhat controversial, but nobody really can doubt that our atmosphere is warming gradually.
“The question is how much of our production of carbon dioxide as humans is affecting that. Most scientists believe [humans] have a very strong effect, there are other reasons, but human combustion [of fuel] is basically what it is.”
He said the event, which will begin with refreshments at 6:30 p.m., followed by the program presentation at 7 p.m., will focus on the carbon cycle between the atmosphere and biosphere, which Bostick referred to the later as “the living part of the Earth,” and the cycling going on within the Earth.
“Carbon gets locked up sometimes for many millions of years in the form of coal and petroleum, but we are releasing that carbon at an alarming rate, so we’re going to run out of it pretty quickly. We’re going to run out of gas,” Bostick said. “The two problems I’m going to address are, No. 1, warming and secondly, resource depletion.”
Bostick said the program will provide information on how individuals can lower their carbon dioxide production as well as bring awareness to gasoline’s role as a non-renewable natural resource.
“I want people to understand we all need to do our share in reducing our carbon footprint and if anything, just to delay the depletion of our fuel and secondly to slow down the rate of warming,” Bostick said. “We need to think about the next generation, I suppose. I’m not sure if the previous generation thought much of us, but I think we’re better people than that in many ways.”
He added, “I’m a retired biologist and this is a topic that has been on my mind for decades.”
The event comes about two weeks prior to Earth Day, which this year has the theme “The Face of Climate Change.”
“Many people think climate change is a remote problem, but the fact is that it’s already impacting real people, animals and beloved places all over the world. And these Faces of Climate Change are multiplying every day,” Kathleen Rogers, president of Earth Day Network, said in a press release. “Fortunately, other Faces of Climate Change are also multiplying every day: those stepping up to do something about it. For Earth Day 2013, we’ll bring our generation’s biggest environmental challenge down to size — the size of an individual faced with the consequences.”
