Climate change, ethics and sustainability: An innovative approach

Climate change is a phenomenon nowadays that is well studied in the field of natural sciences. The aim of this article is to contribute an innovative approach and ethical sustainability to tackle possible solutions on climate change. It is also focused on how to synthesize different approaches on areas being affected. Hence, human being is included in the basic variable of change in the framework of fundamental ecology. That is why it is important to consider a broader view of climate change from historical perspective.


Global warming

The increase in Earth’s average temperatures at different latitudes is clear evidence that human action influence the process. The elimination of greenhouse gas particularly carbon dioxide and other gases which is known to increase temperature need to be address. Also the preservation of plant and animals as well as the biodiversity of the ocean and other ecosystems requires attention. Global warming on the other hand increased temperature, sea level rise, acidification and deterioration of habitat draws awareness of human being conditions.

Climate change: a broader vision

Science in different field conducted research study about the phenomenon of climate change. These includes geology particularly stratigraphy that focus on the study of stratified sedimentary, metamorphic and volcanic rocks.The archaeological stratigraphy that deals with the strata of soil according to age. In which the older is found at the deepest portion and the younger one is on the top. Moreover, paleontology is one of the considerations wherein the remains of living existence have been recorded through time.

The concept of sustainability

Sustainability in broader concept pertains to the ability to endure satisfaction of the present needs without compromising the future generation. It is a feature by which system or element remain functional and active over time. Resources can be used responsibly to ensure the balance in the economy, environment and social welfare.Climate change is a global problem implicating many countries especially those that are affected directly.


Therefore, the approach on climate change needs to consider the anthropological, geological, paleontological and ethical perspectives. Global warming is the key factor to resolve this phenomenal problem, since nature does not have an infinite resources. It does not have unlimited capacity to regenerate as a results, all living existence pay the price for exploiting the natural resources.

Global Carbon Cycling on a Heterogeneous Seafloor

Carbon, nitrogen and oxygen are the fundamental elements of life on Earth. Global carbon varies in amount and its capacity to provide realistic ecosystem response

to environmental changes. In the past century ecological changes increased and the prediction of  the important role of the ocean in global carbon cycle







Where Has All the Carbon Gone?

seafloor biotaGlobal carbon  illustrate the seafloor heterogeneity that influence biodiversity and offers substantial variability in biological process.Transformation of organic matter into living tissues that respires oxygen and releases carbon dioxide add to the global carbon cycle. Increase in population attributes to the changes in global carbon including species response to the global environmental changes. On the other hand carbon cycling from shallow to deep seafloor ecosystems emphasizes the importance of organisms in global carbon models. Indeed, seabed ecosystem varies in organic matter that associate to the increase of global carbon processing.


Biogeochemical and Biological Model of carbon estimates

Carbon cycle on the seafloorGlobal carbon turnover has two simple approaches. First, the used of widely develop geochemical model of carbon to the deep ocean. As well as the production of organic matter near the surface and net remineralizaton of water column dominates global carbon. On the other hand lateral transport and interaction of biological pump comprises at least 50% organic carbon to the seafloor. Second, the used of biological based turnover rate calculated as sediment oxygen consumption rate over the seafloor standing biomass. Organisms consuming organic matter draws parallel effect to the total biomass on global carbon turnover.


Indeed, global carbon cycles requires better model to create not only the precise estimates of carbon degradation. But also on more specific projections on environmental changes. The seafloor biota in global carbon patterns also affects carbon processing. Furthermore, cautions in drawing inferences is needed in determining the flows of global carbon cycling. Thus biogeochemical  models does not totally lodge significant variables considering the changes in abiotic and biotic. Therefore, it is needed to generate proper evaluation in global carbon cycles because it emphasizes various aspects on global climate change.
