This paper argues that the belief that the rapid growth of the human population will inevitably lead to a major ecological disaster is neither intuitively nor empirically tenable. A significant portion of the world's pollution comes not from overpopulated poorer nations, but from Western nations with very low population growth rates. On the other hand, most of this damage is the result of misguided government policies, and not Western overconsumption. Overpopulation is not likely to be a problem environmentally because Malthusian predictions are often made based on the assumption that current rates of resource use and population growth rates will remain the same. Such assumptions ignore the critical role that adaptability has played in allowing humans to avert Malthusian crises. Substitution of products, innovative production methods, and technological changes all ensure in the long run, very few of the facts that predictions are based on will remain fixed.

This paper aims to develop an initial understanding of the Lean Six Sigma methodology since its inception and examine the few Lean Six Sigma dimensions as a research domain through a critical review of the literature.
The paper is structured in two-part. The first part of the paper attempts to dwell on the evolution of the Lean Philosophy and Six Sigma methodology individually and the emergence of Lean Six Sigma methodology, covered under the Lean Six Sigma: a historical outline section. The second part of the study examines the dimensions associated with Lean Six Sigma such as frameworks, critical success factors, critical failure factors, type of industry, performance metric, year, publisher and journal, based on a total of 223 articles published in 72 reputed journals from the year 2000 to 2019 as a literature review.
The adoption of Lean Six Sigma, as a continuous improvement methodology, has grown enormously in the manufacturing and few service sectors such as health care and higher education during the past decade. The study revealed that researchers came out with conceptual frameworks for the implementation of Lean Six Sigma, whereas the validation through case studies seems to be lacking. The integration of Lean Six Sigma and other approaches with a focus on sustainability and the environment has emerged as a research field. A few of the most common critical success and failure factors were identified from the articles studied during the study.
This paper may not have included some of the studies due to the inaccessibility and selection criteria followed for the study.
This paper will provide an initial introduction on Lean, Six Sigma and Lean Six Sigma and research insights Lean Six Sigma to beginners such as students, researchers and entry-level professionals.
