Climate change is probably the most substantial issue ever to have faced human political, social and financial frameworks. The risks are enormous, with serious vulnerabilities and dangers, the economic matters questionable, the science assaulted, the governmental issues severe and muddled, the psychology perplexing, the effects annihilating, the re...

Have you ever missed an event because you were confused about days and dates? Do you remember the date of any specific day without looking at the calendar? Is the current Gregorian Calendar efficient enough for usage, and does it facilitate our life or make it more complicated? Have you ever thought about a simpler way to calculate days and dates in a year without using a calendar? All these questions are answered in this paper, in which authors propose two contributions, (a) a new mathematical formula that calculates the number of days in any month in the Gregorian calendar for any year, including the leap years, (b) an original optimization method that creates optimal perennial calendars. Results show that there is more than one way to create a perennial calendar using the proposed optimization model, in which the number of days in each month does not change, neither the dates. Hence, all months have the same sequence of days and dates. In other meaning, Monday becomes the first day of every month, and Sunday becomes the last day. Consequently, the calendars become much easier to memorize, and it becomes simpler to predict the days and dates in any year. In addition, the proposed optimal perennial calendar system reduces the energy demand and pollution worldwide, in which it has less impact on the environment and climate change compared to the Gregorian calendar. This is due to the fact that less printed-out calendars are produced, and less time is spent on the digital calendars to check the dates and days.
... [11]. The significant release of GHGs is accountable for the outrageous environmental occurrences such as hurricanes, flooding and drought, which become progressively intense with further release of GHGs, prompting injuries, severe communicable maladies and deaths [37][38][39]. Health issues such as asthma and heart disease are linked to the atmospheric release of pollutants from the brick making industries [34]. Other symptoms such as severe cough, phlegm, bronchitis and wheezing are associated with brick making [30]. ...
... In addition to air pollutants released from brick making, is the generation of Greenhouse gases (GHGs), mainly from combustion of fossil fuel. Significant release of GHGs such as carbon dioxide, nitrogen oxides (NO x ), nitrous oxide (N 2 O), nitric oxide (NO) and methane are partly responsible for the unusual changes in climatic condition [34,35,39]. Globally, about 70% of total GHG emissions are attributable to the burning of fossil fuel from the industrial sectors [37]. ...
... The continual increase in anthropogenic emissions of GHGs, as it is currently being experienced, is dynamically modifying the climatic conditions, both at the international and local level [69]. Today, climate change is becoming a global issue, owing to its increasing multifaceted and interconnected adverse effects [39,70]. The effects of climate change on meteorological processes and environmental events are well documented [38]. ...
The brick making industry, despite its contribution to environmental pollution, plays a major role in the economic growth of South Africa, with the traditional technology accounting for a significant proportion of the total clay brick production. The aim of this study is to undertake a comprehensive description of the production phases of the traditional brick making sector in Vhembe district and how this contributes to air pollution. The study comprised a series of interviews and questionnaires of key role players from two small villages, Manini and Tshilungoma in the Vhembe district. In-situ observations of the production methods and phases were also undertaken between June and December 2019. The brick making production phases used in Vhembe district are excavation, preparation, moulding, drying and firing. An average estimate of 34,683 bricks is fired monthly per brick kiln in Vhembe district. Emissions from brick making organisations had resulted into several public health and environmental risks. To reduce environmental degradation, the incorporation of industrial and environmental wastes into brick making and the gradual transition to environmentally friendly technology such as Vertical Shaft brick kiln (VSBK) should be embraced. Thus, traditional brick making implemented with appropriate sustainable environmental technology has the potential to improve the socio-economic status of the brick makers.
