While listening to NPR this morning, they had a brief clip about Carbon Dioxide and NASA research. Now, a lot of people might not get excited over this, but for me? It's ear porn. Totally addictive and arousing.
What in the world is NASA up to? Well, they are sending a satellite called OCO (Orbiting Carbon Observatory) into space to track carbon dioxide emissions. More specifically? They want to find out where it is going. We know that about half of all carbon dioxide emissions stay in the air, but we have absolutely no idea where the other half goes.
Carbon dioxide is necessary for life as we know it, but too much of a good thing is well, too much. Here is my science lesson for the day:
Carbon dioxide is composed of two (2) oxygen atoms which are covalently bonded to one (1) oxygen atom. It likes to fluctuate with the seasons, increasing in the fall and winter and decreasing in the summer. Why? Well, plants need CO2 for photosynthesis. They make sugars which may be consumed in respiration or used in raw material to produce polysaccharides such as starch and cellulose, proteins and other organic compounds which are required for plant growth and development. Plants also need it to breathe--or respiration--as well as every other living being, whether it is in a direct or indirect form.
Interestingly enough, plants emit CO2, so it is only when they are in their growth stage that they are net absorbers of carbon dioxide.
So, why is there so much of it? Well, emissions are one of the key culprits. All of those cars we are putting on the road every year don't help. The burning of fossil fuels, lack of clean energy, all applies.
The biggest culprit? Loss of vegetation. Plain and simple. Open up
Google Maps and check out the carbon dioxide map. When we lose our forests and vegetation, we lose "carbon sinks". Great big areas that absorb and use the carbon dioxide for their own natural processes.
Carbonic acid now comes to mind when I think of carbon sinks. Earths oceans are in peril due to the carbon dioxide they are absorbing. The absorbtion creates carbonic acid, increasing the acidity of the sea water and adversely affecting all living things in the sea water. In an article from August 2007,
Mother Jones news stated that coral reefs were disappearing twice as fast as rainforests.
What can I do? Cut back my carbon emissions. Walk where I might have drove. Use less items that require excess carbon output. This goes from the food I purchase to the way I do my laundry. Support legislation for tackling climate change and stay informed.
