ENVIRONMENTAL SCIENCE TOWARDS A SUSTAINABLE EARTH © 2018 focuses on the all-important imperative to sustain our mother Earth, enabling the planet to support an increasing global population and conserving the finite resources needed for man’s continued survival and existence.
It is divided into three units. The first unit opens our minds to understand the ethics of sustainability and how it is achieved, the ecological foundations of environmental science, and the knowledge and understanding of how our biosphere and the various ecosystems work towards achieving the needed balance of nature. The first unit also covers the unifying themes that guarantee the desired harmony of man with his environment.
In Unit 2, the global and national environmental issues affecting our biosphere are discussed. Strategies and actions for improvement and resolution of these issues are also discussed in this unit. Chapters 4 and 5 both tackle relevant environmental issues affecting both non-living (air, water, land, energy) components of the ecosystem. In addition, Chapter 5 is focused on the living components of our biosphere. The objective of Unit 2 is to raise consciousness and awareness among our youth to preserve and conserve Earth’s resources. Sustainability of these natural resources is crucial to the continued survival of the human race.
Man has the power to either destroy or renew and conserve the environmental resources, so Unit 3 continues with the role of humans in the whole ecosystem. A discussion on the global population and the principles of population ecology is aimed at understanding better the ecological footprint humans leave on the planet. In this unit, there's also an exploration on how this footprint can be managed and reduced .
