Environmental Biology is the study of organism’s interaction with the environment, and how they adapt to changing environments. It explores the interconnections among biology, ecology, evolution, and conservation. Environments consist of many components including both physical features, such as climate and soil type, and biological features, such as prey and predators. The term environmental biology has wider connotations than ecology because it includes the study of humans in the environment, so you will find such subjects as agriculture, pollution and the unnatural surroundings. Understanding the ecology of an area is like trying to put together a gigantic, multidimensional jigsaw. Some pieces are the individual species in the area.

Environmental geology unites the core foundation of environmental science and places particular emphasis on the study of geology and executing it to real-world situations. It is an applied science concerned with the practical application of the basis of geology in the iron out of environmental problems. It includes Hydrogeology, Environmental Mineralogy, Hydro geochemistry, Soil Mechanics etc. The fundamentals concepts of environmental geology are Human population growth, Sustainability, Hazardous earth processes etc. Environmental Geology employs in geologic hazards, topical issues, and natural resources of concern to society such as change in climate and provides sound advice about how humanity can live responsibly on Earth.

Research on environmental geology emphases on the physical and chemical processes occurring at or nearby the Earth’s surface impacting by human activities. Hydrogeology is important nowadays  as some piece of the world are sacred with frequent rainfall and plentiful surface water resources, but most countries need to use the water that is underground stored to supplement their needs. Environmental geology applies geologic information to the solution, prediction and study of geologic complications such as Earth materials, Landscape evaluation, Natural hazards, Environmental impact analysis and remediation.

Environmental Climatic Factor

Climatic factors include rainfall and water, light, temperature, relative humidity, air, and wind. They are abiotic components, including topography and soil, of the environmental factors that influence plant growth and development.

These factors may be biotic (living) and abiotic (non­living). The sum total of all these factors constitutes the environ­ment of an organism.

1)      Climatic or Aerial factors: 

·         Light

·         Temperature

·         Water

·         Atmospheric gases

·         Humidity

2) Topographic or Physiographic factors:

·         Altitude

·         Direction of mountain chains and valleys

2)      Edaphic factors:

·         These deal with formation of soil, its physical and chemical properties and details of related aspects

3)      Biotic factors:

·         These are all kinds of interactions be­tween different forms of life. These are plants, animals, micro-organisms.

Energy storage is the capture of energy that produces energy for onetime or later several times. A device that stores energy is called accumulator. Both wind and solar energy in recent years can help to produce valuable source of renewable energy. Wind turbines and Photovoltaic by installation can produce enough energy to sustain themselves. Bulk energy storage can be dominated by pumped hydro which accounts for 98% global energy storage.

Environmental science is a multidisciplinary academic field that combines physical, biological and information sciences to the environmental study. The social science fields that are incorporated into environmental science include geography, economics, and political science. Philosophy and ethics are the two fields within the humanities that are also included in environmental science. The surface environment of the Earth is disciplined by interactions between the deep Earth, the atmosphere, the hydrosphere, and the biosphere. This intercommunication occur on timescales ranging from picoseconds for chemical reactions on mineral surfaces to the millions of years over which plate tectonic processes and earth’s evolution take place. Investigations are open on what shapes our world and the environment in which we live, in order to understand the interactions between Earth's geology, atmosphere, biosphere, oceans, and human responses and roles

In spite of the fact that there are contradictions among from various controls and global associations have each offered measures. While supportability pointers, records, and revealing frameworks increased developing prevalence in both general society and private parts. 

A biological system is a group of living beings in conjunction with the nonliving parts. Biotic and abiotic parts are connected together through supplement cycles and vitality streams. Biological communities are controlled both by outside and inner variables. Outside variables, for example, atmosphere, parent material that structures the dirt and geography control the general structure of an environment. Biodiversity influences biological community work to do the procedure of aggravation and progression. 

Environmental biotechnology is used to study the natural environment. Environmental biotechnology could also imply that one try to harness biological process for commercial uses and exploitation. Molecular biotechnology is the use of laboratory techniques to study and modify nucleic acids and proteins for applications in areas such as human and animal health, agriculture, and the environment. Molecular biotechnology results from the convergence of many areas of research, such as molecular biology, microbiology, biochemistry, immunology, genetics, and cell biology.  

An environmental disaster is a natural environment due to human activity. Environmental disasters can have effect on agriculture, biodiversity, economy and human health. . Disasters are not random and do not occur by accident. They are the convergence of hazards and vulnerable conditions. Disasters not only reveal underlying social, economic, political and environmental problems, but unfortunately contribute to worsening them. Such events pose serious challenges to development, as they erode hard-earned gains in terms of political, social and educational progress, as well as infrastructure and technological development.
