Biodiversity is several different species located in one ecosystem. Conservative Biology is the scientific study of biodiversity that’s main focus is protecting species and biodiversity. These two terms are related because one explains what biodiversity is and the other is the

ABSTRACT Ecosystem service is a new term in the context of our country. The concept of payment to environmental services is a broad umbrella for the conservation of watershed. Watershed is the important part in the livelihood of people. With the watershed people survive and help it thrive. People here are the makers as well as destroyers. Within the watershed there are upstream dwellers that mainly provide the service to the dwellers living downstream. Hence this project is for the conservation

Kolbert’s logical appeal strengthens her argument‚ as she weaves a compelling thread of logic and scientific evidence into it. For instance‚ Kolbert writes about the introduction of rosy wolfsnails in Hawaii in the 1950’s to exemplify the repercussions of introducing new species in a habitat‚ such as threatening the well-being of native ones (Kolbert 2014‚ 203). According to Kolbert‚ Hawaiians first introduced the rosy wolfsnail in their island to reduce the population of giant African snails‚ which

Introduction The Earth is home to various forms of life contributing to the endless biodiversity that we see in our daily lives. In environments around the world there are distinct correlations between the environment and adaptations acquired by the organisms that live there. It has been shown that these adaptations

The restoration of the regions in San Francisco Estuary are based on many applications from water use‚ land use‚ dredging and waterway modification‚ wetlands management‚ and the pollution prevention and reduction fazes. I will be taking a look at the aspects of the pollution prevention and reduction within the San Francisco Estuary program. Estuaries are unique‚ dynamic transition zones‚ between the watershed and the world ocean system. In this paper I will try to discuss the abiotic and biotic

1.2 How have environmental cycles changed? The capacity of ecosystems to provide benefits to humans‚ that is to provide ecosystem services‚ derives from environmental cycles of water‚ nitrogen‚ carbon‚ and phosphorus. These processes have in some cases been significantly modified by human activity. Changes have been more rapid in the second half of the 20th century than at any other time in recorded human history. Water cycle: Water withdrawals from rivers and lakes for irrigation‚ urban uses‚

Watershed Management and Soil Erosion Forests provide a buffer to filter water and to hold soil in place. They sustain water and soil resources through recycling nutrients. In watersheds where forests are degraded or destroyed‚ minimum flows decrease during the dry season‚ leading to drought‚ while peak floods and soil erosion increase during the wet season. Flooding along the Baram River in Sarawak has increased significantly since logging began‚ the major floods occurring in 1979 and 1981.168

It is important that forests around the world are protected. The primary reason being the world’s biodiversity and climate change‚ both of which are extremely dependent on forests and people need them to survive. There are abundant ways we can and should use the forest more sustainably to be assured that they will be around for future generations. Some
