Abstract

Global warming, or what has been called the Greenhouse effect, refers to an average increase in the earth\'s temperature, which in turn causes changes in climate. The Greenhouse Effect is the results from a four step process. First, sunlight radiates from the sun, through space to earth\'s atmosphere. Second, the sunlight enters the atmosphere and hits earth. Some of it turns into heat energy in the form of infrared light. The heat is absorbed by surrounding air and land, which in turn makes it warm. Third, infrared rays, which are remitted into the atmosphere, are trapped by greenhouse gases. The gas absorbs the light and is remitted back to the earth\'s surface and warms it even more. Greenhouse gases primarily carbon dioxide, methane, and nitrous oxide. Global warming caused by greenhouse effect, feedback effect and solar cycle variations. Global warming causes climate changes and extreme weather events, rising sea levels, increasing of precipitation are likely to have detrimental effects on human health that accompany malnutrition. The objective of this study is to give information about global warming, and how to change people attitude toward environment by conservation, efficiency of energy, reduction of energy, and educational approach.

Abstract

Human behavior is a part of the ecological system, therefore overcoming the ecological crisis and living resources need to explore human traditions, way of life and human behavior toward natural resources. Understanding and translation of human harmonious relationship with all elements along with other living beings is a form of human ecological intelligence. The objective of this study was to describe the traditions and coastal communities behavior that contains the value of ecological intelligence in coastal biodiversity conservation. The study was based on observation, focus group discussion and identification of Bajau coastal community tradition in their lives and livelihoods on fishing, as well as the behavior toward biological resources. Bajau coastal communities settled in three villages in Pohuwato regency, Gorontalo. There are two themes that contains the value of ecological intelligence of  Bajau communities in the conservation of biodiversity, namely; mamia kadialo in tradition of fishing, and fishing behavior. The prohibition in the tradition of mamia kadialo contains the value of conservation of biodiversity. Usage of simple equipment on fishing activities provide a positive ecological consequences for the conservation of coastal biodiversity.
