Introduction Despite the erection of a smoking ban in Ireland, about 20% of the population still continues to smoke. In contrast to alcohol, marijuana and other illicit drugs, tobacco use is less likely to decline as the pregnancy progresses ((Day et al. 2000; Cornelius et al. 1995). The reason for this is that nicotine is … Read more
Nowadays, populations throughout the world have grown rapidly, rural areas are becoming less populated and urban centers are rampant, reflecting constraints on the availability of resources to meet their needs. Territories that have environmental problems are more complex than that presented in recent years. In this way, urban growth represents a negative aspect for sustainability, … Read more
Discussion and Scientific explanation The goal of this experiment was to synthesize multiple soaps and detergents using different starting materials and methods to then determine which one had the most desirable qualities for the environmental group. The three starting materials used were shortening, lard, and vegetable oil. Each of these materials first went through a … Read more
Studies of the extinction rate over the past few centuries conclude that it is significantly greater than the background extinction rate, matching or exceeding that during the five previous mass extinctions (Barnosky et al., 2011; Dirzo et al., 2014; Ceballos et al., 2015). Understanding what is shaping extinctions, and how species respond to these pressures, … Read more
CHAPTER 1.

Introduction 1.1 Current Scenario: The usage of energy is increasing with the increase in human population. Remarkable actions have been taken to create advances for boosting the use of renewable energies, for example, hydroelectric, wind, and solar energy. As the ordinary fossil energies are not economical energy sources. One of the main problems is that … Read more
Endocrine disrupting chemicals (EDCs) interfere with the endocrine system of humans and wildlife, influencing sexual development even at sub-lethal concentrations (in the ng/L range) and could generate alterations at population level including local extinction (Kidd et al., 2007). Within EDCs, estrogenic chemicals or xenoestrogens can generate oxidative stress and feminization in wildlife, and induce proliferation … Read more
Theoretical Framework Integrated waste management theory is a theory that explains the system of waste handling which entails separating waste materials according to type and finding the best use for discarded materials, which may or may not include depositing them in landfill. This theory goes further to explain the fact that an attempt must be … Read more
The drilling of oil in the Arctic National Wildlife Refuge has been a controversial topic to discuss over the last couple of years and even today discussion takes place in re-opening the consideration for using the grand piece of land as an area to drill for oil.

Energy plays a major role in promoting social and economic development. Approximately ninety percent of the global energy supplies come from carbon-based fuels (Rambo, 2013). However, their emissions are connected to environmental pollution. Moreover, they cause an increase in global temperatures besides interfering with climatic patterns. Furthermore, exposure to indoor results in respiratory diseases in … Read more
