    Biodiversity refers to the variety of living species on Earth. It encompasses a vast network of both simple and complex organisms, with estimates ranging from about five million to one trillion and beyond. This network provides nature with clean water, air, fertile soil, climate control, possible remedies, food and nutrition, recreation and restoration, and stimulated inspiration. However, this important living network is vulnerable and in danger. Millions of plant and animal species are at risk of extinction and/or gradual elimination. The intensive extraction of certain components of biodiversity in the name of growth and development has greatly impacted our ecological and natural living equilibrium. To avoid irreversible natural disasters, the decline of biodiversity must be stopped immediately. This will provide time and the much-needed opportunity to restore biological complexities, and ecosystems that have been impacted.  

    Module Goals and Objectives

    Upon completion of this module, you will be able to:
    1. Describe methods and techniques used to measure and assess biodiversity, including species richness, species abundance, and diversity indices.

    Living organisms need energy to perform life-sustaining “work” to survive. For nearly all living systems on Earth, the sun is the ultimate source of that energy. Over time, we humans have developed an understanding of energy that has allowed us to harness it for uses well beyond basic survival. The development and evolution of human society are largely attributed to our relationship with energy. The first major advancement in human understanding of energy was the mastery of fire for cooking and heating. Modern civilization is especially dependent on energy and some of its most distinct characteristics such as population growth, environmental impact, and climate change are all a consequence of energy use. We use energy to heat and light our homes; power our machinery; fuel our vehicles; produce plastics, pharmaceuticals, and synthetic fibers; and provide the comforts and conveniences to which we have grown accustomed in the industrial age. Societal complexity, affluence, and the gap between poor and rich people are all directly related to our level of energy consumption.

    Module Goals and Objectives

    Upon completion of this module, you will be able to:

    1. Define energy and explain its properties.
    2. List specific examples of non-renewable energy sources.

    Waste from various sources is an increasing concern for the environment as the amount of waste we produce daily is enormous. Biodegradable waste is substances that can be decomposed or degraded by microorganisms and other living organisms. These substances are mainly added to the environment from plant and animal sources. Some biodegradable substances are decomposed easily in the natural environment, and some take a long time to degrade. Non-biodegradable waste is mainly inorganic substances such as plastics, cans, chemicals, bottles, etc. Both biodegradable and non-biodegradable waste has some adverse effect on the environment as both cause pollution that makes our habitat inhabitable. Billions of tons of waste are generated every year. 

    Module Goals and Objectives

    Upon completion of this module, you will be able to:
    1. Critique biodegradable and non-biodegradable substances that are constantly being added to the environment.

    A wide range of environmental hazards we come across in almost all habitats and public and private properties including, but not limited to, the work place, construction areas, parks and recreational areas, industries, and living beings. All living beings experience them directly or indirectly in their habitats – local, state, regional, national, and international. Environmental hazards can also be classified into three interrelated categories (biological, chemical, and physical) based on the properties of their causes and interactive behavior. 

    Toxicology deals with a variety of chemical hazards that operate over longer periods of time (rather than as events), and they include climatic factors and many kinds of chemical and thermal pollution. Depending on the intensity of exposure, organisms may suffer acute toxicity resulting in tissue damage or even death, or a less-obvious chronic damage that results in decreased productivity (source: B. Freedman). For instance, excessive levels of sulfur dioxide emit from the industries into the atmosphere will reduce the productivity of vegetation and its quality or even loss of vegetation.

    Biochemical cycles refer to the processes through which essential elements are circulated among all living organisms on Earth. Once common elements move through the atmosphere, lithosphere, and biosphere, they can take on various chemical forms. Six elements are consistently recycled in organic molecules, namely: carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. These elements play a vital role in sustaining life on Earth. For instance, carbon is a key element that forms the backbone of organic macromolecules. Nitrogen, on the other hand, is a critical component of nucleic acids such as DNA and RNA and is important for agriculture. Phosphorus is a key constituent in the backbone of the DNA and RNA structures. Hydrogen and oxygen can be found in water as it changes forms as a liquid, vapor, or ice. Lastly, sulfur is the main constituent of protein and is also released through different layers of the ecosystem. The picture shows how carbon, nitrogen, and phosphorus nutrients are in a continuous cycle on the planet Earth.

    In this section, we will discuss how the natural greenhouse effect on Earth helps to keep the planet's surface warm and the role played by greenhouse gases (GHGs) in this process. GHGs work by reducing the rate at which Earth can release the absorbed solar radiation, thereby maintaining the temperature of the planet. However, the concentration of GHGs, especially carbon dioxide, has been increasing due to human activities, which can potentially intensify the greenhouse effect and cause global warming. This change could have severe consequences for the environment as well as the human economy and natural ecosystems.  

    Module Goals and Objectives

    Image: Ken Lund via Wikimedia Commons, CC-BY-SA

    Agriculture was probably first practiced in the Fertile Crescent, a region of southwestern Asia that includes parts of what are now Iran, Iraq, Israel, Jordan, Lebanon, Syria, and Turkey. Similar developments likely occurred at about the same time in China, although the archaeological evidence is less clear. Other cultures discovered the benefits of agriculture later through the domestication of local species of plants and animals (for instance, in parts of Central America, western South America, and New Guinea). However, in other regions, domesticated species were mostly imported from elsewhere, as occurred in Australia, Europe, and North America.
