Carbon and its impacts on life

Posted on Posted in Science & Engineering

Carbon is the fourth most abundant element in the universe and the backbone of life on earth. Most of the earth’s carbon, about 65,500 billion metric tons, is stored in rocks. The rest is in the ocean, atmosphere, plants, soil, and fossil fuels. All living things or organic matter consist of carbon atoms.

Carbon considered as a special element that can form so many different compounds due to its unique atomic structure. After oxygen, carbon is the second most common element of the total human body weight. We made of carbon, we eat food consists of carbon, and our civilizations – our economies, our homes, our means of transport – are built on carbon. Humans and animals eat plants that contain carbons and use them to create body tissues. They also produce carbon dioxide during respiration process. Plants, meanwhile, absorb carbon dioxide (CO2) for photosynthesis, produce carbohydrate molecules (sugar) and release oxygen into the atmosphere.

Carbon and the global warming

We need carbon, but that need also entwined with one of the most pressing problems facing us today: global warming and climate change. The recent climate change is a global-scale issue that has major implications for human and biological systems. It causes massive economic and environmental destructions, which often coupled with the loss of many human lives. This change of climate is driven primarily by the increase in the concentrations of greenhouse gases (GHG) in the atmosphere. This increased GHG principally as a result of human activities by rapidly rising rates of combustion of fossil fuels and the changes in land use.

Carbon cycle

The global carbon cycle is one of the major biogeochemical cycles, which divided into geological and biological cycles. The former operates on a timescale of millions of years while the latter involves thousands of years. Meanwhile, the biological cycle includes the living things through the processes of photosynthesis and respiration. Since all living organisms made of carbon compounds, the

biological carbon cycle is, therefore, playing a vital role in the carbon exchange process. Both types of the carbon cycle are substantially dependent on the chemical reaction with the presence of water. The cycles of carbon, nitrogen, and water should also be considered. These three cycles are interconnected and playing significant roles in the carbon sequestration process both on land and in the ocean.

Soil carbon

Soils located between base rock, atmosphere, and vegetation. They represent a home of many organisms where various biogeochemical transformation and processes take place. Soils also have properties that enable them to store many substances, which crucial to sustaining human life and ecosystem processes. Therefore, soils have been a topic of scientific research for more than a century. Meanwhile, soil mechanics has become a major subject in the civil engineering study. The most important applications of soil science are the diagnostic and maintenance of soil fertility, particularly its dominant role in the terrestrial carbon balance. Considering the potential of soils to store carbon with almost unlimited capacity, we highly recommend scientific research works on this fascinating topic.

  1. As you will inevitably learn on your path to losing weight, effective weight loss is not only about watching what you eat, but much more about changing your lifestyle. This means changing your habits and how you approach your day-to-day life. Read this information to help you throughout the process.

  2. Some people, especially those running on busy daily schedules tend to use the pills to help maintain weight since they can not afford to follow all the diet programs. This is not advised. It is recommended that one seek advice from a professional in this field before using the pills. This can save one from many dangers associated with the misuse.

    The diet pills should always be taken whole. Some people tend to divide the pills to serve a longer period of time. This is not advised and can lead to ineffectiveness. If it is required that one takes a complete tablet, it means that a certain amount of the ingredients are required to achieve the desired goal. It is also recommended that one does not crush the pill and dissolve it in beverages. Chemicals found in beverages have the potential of neutralizing the desired nutrients in the pill thereby leading to ineffectiveness. The best way to take the tablets is swallowing them whole with a glass of water.

    The diet pills speed up the metabolic processes. This is the key factor that leads to the burning of all the fats in the body. This means that one passes out lots of urine, which subsequently leads to dehydration. It is imperative that the user take lots of water round the clock. This will help curb dehydration, which can lead to health problems. In addition to that, water offers the required medium for the function of the nutrients and elimination of the fats.

    When buying the review of diet pills, it is imperative that one gets the most recommended dose. People tend to compromise the quality and effectiveness of the tablets due to the variation in cost. The low priced pills depict poor quality, which means their effectiveness is not reliable. Some have also been found to cause health problems. The dose should also be taken as recommended. Over dose will not speed up the process but rather lead to complication. This will increase risk of side effects. If the taking of the pill is forgotten, do not take more to compensate for the lost time.

    The diet plan enclosed with the diet pills has also to be followed. According to the requirements, the termination of the diet must be done even with no results. This means your body is irresponsive.
