Pollution - undesirable state of the natural environment being contaminated with harmful substances as a consequence of human activities.
Although normal quantities of CO2 is use in photosynthesis by plants, abnormally high levels of CO2 is undesirable, and pollute the natural environment That is why CO2 alarms are available in most stores like Walmart, Lowes, Home Depot, etc. As a matter of fact, you can buy a dual CO2 and smoke alarm in a single package and save a few bucks. Over the last 50 years, CO2 has been contaminating earth's atmosphere by concentrating in higher and higher levels. High levels of CO2 is particularly dangerous to animals and humans; because, CO2 is absorbed into the blood stream much faster than oxygen, (eg hundreds of times faster than oxygen), which can lead to many medical complications including death. CO2 is definitely a pollutant when present in high concentrations and fits perfectly in the definition I found on Google and included at the top of this post. Getting back to my origianl post, perhaps you would like to address the questions I ask Publius: Do you believe that pollution over the last 50 years has increased, due to population growth and industrial, real estate, and technology advances. If so, do you think that increases in pollution can cause problems? If pollution exits, and is a problem, do you believe it should be eliminated, or at least minimized, and how do you assess the expense you are willing to pay for a cleaner earth? http://www.buzzle.com/articles/carbon-dioxide-poisoning.html Regards, LelandJ On 12/16/2009 04:50 PM, Michael Madigan wrote: > Carbon Dioxide isn't pollution, it's what plants need to live on. > > >> You're denial adds pollution to an already over polluted >> world. >> >> Let's approach global warming and climate change from a >> different angle. >> >> Do you believe that pollution over the last 50 years has >> increased, due to population increases and industrial, real >> >> estate, and technology advances.
