Environmental studies and its scope: Environment is nothing but the nature composed of bothbiotic and abiotic factors. It has profound effect over the living organisms. It also exertsinfluence over their metabolic activities. It causes even evolution to occur as the environment isdynamic and ever changing. Its scope is so wide that it has got relation with every science andscientific aspects in general and biology in particular. Its study makes the man to understand itsimportance. He would be able to take necessary steps to protect it though nature can take care ofthe human beings. Environmental Science will be a growing field for the future with the growingconcerns about our global warming and climate changes. Other fields such as ecology, botany,and meteorology besides all other major branches of the science, arts and commerce.Importance/Significance of the Environmental Studies: Environmental studies is concerned with the day today interaction with the surroundings with which human being is closely associated. is related to many branches of the science and is an interdisciplinary problems. is concerned with the importance of wild life its protection explains the significant role of biodiversity in establishing ecological balance deals with different types of ecosystems, biotic and abiotic factors and their role in the significance and sustenance of ecosystems. is concerned with different types of food chains, food webs, productivity, biomass, carrying capacity of ecosystems. deals with various types of interrelationships existing between living and non living organisms and also between different types of living organisms such as symbiosis, mutualism, commensalism, parasitism, competition, antibiosis etc., gives information relating to population explosion, growth and development, impact of population growth on the resource consumption and national economy. Explains the coexistence of both living and non living organisms and their contribution to the nature for its sustenance. Deals with relation with ethos and the impact of ethical principles in the conservation of wild life, biodiversity and environment. Explains the significance of forests and their products in the human routine and in countrys economy. Gives information about water conservation, watershed management and the importance of water as a universal solvent and the importance of the same in various physiological, biochemical, internal systems and external environment. Natural global warming is a very sticky subject in the modern world. With a lot of focus on raising awareness about greenhouse gases, carbon levels, and green lifestyles, some may mistakenly get the message that all global warming is created by humans. To the contrary, the Earth has a history of natural climate change that creates warm and cool cycles. While most experts believe that human activity may be primarily responsible for modern climate change, natural global warming may also contribute to rising temperatures and other climate change issues. From what scientists can determine about the planets ancient history, temperature cycles on the Earth are usually fairly stable, but may experience sudden rises or drops in temperature at the beginning and end of ice ages. The sudden increase of global temperature is what allows glaciers to retreat and more temperate climates to establish in what were once realms of ice. This natural global warming may be a result of several planetary adjustments both on the surface and in space.
