(NaturalNews) Scientists from the University of Wisconsin-Madison and the University of Minnesota at Morris have found that increased levels of atmospheric carbon dioxide have led to the rapid growth of certain tree species. The quaking aspen, a popular North America deciduous tree, has seen a 50 percent acceleration in growth over the past 50 years due to increased CO2 levels.

Trees are necessary climate regulators since they process carbon dioxide and give off oxygen. Humans process oxygen and give off carbon dioxide, working harmoniously with natural plant life to maintain proper atmospheric composition. Since natural forests represent about 30 percent of the earth's surface, they are highly effective at segregating greenhouse gases.

The quaking aspen is a vibrant, dominant tree found in both Canada and the United States. It is considered to be a "foundation species", meaning that it helps dictate the dynamics of the plant and animal communities that surround it. Roughly 42 million acres in Canada and 6.5 million acres in Wisconsin and Minnesota are composed of aspen trees.

Elevated levels of CO2 will naturally lead to increased plant growth since CO2 is a precursor to plant food. Tree-ring analyses verified that aspen trees have been growing at an increasingly accelerated pace over the years because of this phenomenon.

Because accelerated growth was not seen in other tree species like oak and pine, scientists admit they will have to further investigate the issue. Similarly, drier regions where the trees were found did not experience the same rapid growth rates as those found in the wetter regions.

Comments by Mike Adams, the Health Ranger

An interesting side effect of increased carbon emissions by human activity is that plants will grow more quickly. CO2 is to plants as oxygen is to humans, so the more CO2 is in the atmosphere, the more quickly many plants can grow.

Of course, plants produce oxygen as the "waste" product of their respiration, and that's a poison to other plants, so there's a natural balancing effect that keeps oxygen and CO2 levels in balance over the long haul.

This is why greenhouse gases are called "greenhouse gases", by the way -- because they turn the planet into a really effective greenhouse where plants grow like crazy. Of course, the clear-cutting of rainforest in the Amazon (and elsewhere) kills any chance of those regions taking part in that accelerated plant growth. Even in a high-CO2 environment, human beings can destroy plant life with bulldozers.

It's interesting that plants and humans breathe the same air but extract very different chemical elements from it: Humans need oxygen while plants need carbon dioxide. For both species to survive, the air needs to contain both chemicals in balance. Currently, the oxygen content of the air is roughly around 20% (and falling).

About the author:Mike Adams (aka the "Health Ranger") is a best selling author (#1 best selling science book on Amazon.com) and a globally recognized scientific researcher in clean foods. He serves as the founding editor of NaturalNews.com and the lab science director of an internationally accredited (ISO 17025) analytical laboratory known as CWC Labs. There, he was awarded a Certificate of Excellence for achieving extremely high accuracy in the analysis of toxic elements in unknown water samples using ICP-MS instrumentation. Adams is also highly proficient in running liquid chromatography, ion chromatography and mass spectrometry time-of-flight analytical instrumentation.

Adams is a person of color whose descendents include Africans and American Indians. He self-identifies as being of American Indian heritage, which he credits as inspiring his "Health Ranger" passion for protecting life and nature against the destruction caused by chemicals, heavy metals and other forms of pollution.

Adams is the founder and publisher of the open source science journal Natural Science Journal, the author of numerous peer-reviewed science papers published by the journal, and the author of the world's first book that published ICP-MS heavy metals analysis results for foods, dietary supplements, pet food, spices and fast food. The book is entitled Food Forensics and is published by BenBella Books.

In his laboratory research, Adams has made numerous food safety breakthroughs such as revealing rice protein products imported from Asia to be contaminated with toxic heavy metals like lead, cadmium and tungsten. Adams was the first food science researcher to document high levels of tungsten in superfoods. He also discovered over 11 ppm lead in imported mangosteen powder, and led an industry-wide voluntary agreement to limit heavy metals in rice protein products.

In addition to his lab work, Adams is also the (non-paid) executive director of the non-profit Consumer Wellness Center (CWC), an organization that redirects 100% of its donations receipts to grant programs that teach children and women how to grow their own food or vastly improve their nutrition. Through the non-profit CWC, Adams also launched Nutrition Rescue, a program that donates essential vitamins to people in need. Click here to see some of the CWC success stories.

With a background in science and software technology, Adams is the original founder of the email newsletter technology company known as Arial Software. Using his technical experience combined with his love for natural health, Adams developed and deployed the content management system currently driving NaturalNews.com. He also engineered the high-level statistical algorithms that power SCIENCE.naturalnews.com, a massive research resource featuring over 10 million scientific studies.

Adams is well known for his incredibly popular consumer activism video blowing the lid on fake blueberries used throughout the food supply. He has also exposed "strange fibers" found in Chicken McNuggets, fake academic credentials of so-called health "gurus," dangerous "detox" products imported as battery acid and sold for oral consumption, fake acai berry scams, the California raw milk raids, the vaccine research fraud revealed by industry whistleblowers and many other topics.

Adams has also helped defend the rights of home gardeners and protect the medical freedom rights of parents. Adams is widely recognized to have made a remarkable global impact on issues like GMOs, vaccines, nutrition therapies, human consciousness.

In addition to his activism, Adams is an accomplished musician who has released over a dozen popular songs covering a variety of activism topics.
