Environmental sanitation – the control of environmental factors that form links in disease transmission. Subsets of this category are solid waste management‚ water and wastewater treatment‚ industrial waste treatment and noise and pollution control. Ecological sanitation – an approach that tries to emulate nature through the recycling of nutrients and water from human and animal wastes in a hygienically safe manner. History The earliest evidence of urban sanitation was seen in Harappa‚ Mohenjo-daro

INVESTIGATING THE ECOLOGICAL NICHE OF THE CRAB USING A FAIR TEST INTRODUCTION: The ecological niche of the crab Hemigrapsus edwardsi. The crab is a member of the Crustacea phylum and is in the family Grapsidae. This crab species is found only in New Zealand on rocky shores. The rocky shore‚ where the crabs studied in this investigation were found is quite exposed. There is a large rock platform that provides small crevices and small rocks which help to protect them from wave action and predators

Importance of the Ecological Footprint Everyone has desire‚ and it will never get satisfied. Because of our desire‚ we use all the resources we can reach or find to produce better product and develop the technology to make our life better and easier. Ecologists have warned us so many times‚ every action has its consequences. One day all the resources on the planet will deplete‚ if we keep on using the resource like this and speed up every year. We all understand the consequences but majority

Ecological Restoration How can we envision an ecological restoration of both physical environment and philosophical/spiritual thought models? Overpopulation‚ overexploitation‚ and human consumption are all contributing to the downfall of our now extremely misused planet. All organisms are now being exposed to drastic environmental changes‚ ones that our ancestors have never experienced. The stability of the Earth has been decreasing severely in the past few centuries because of mankind’s impact

Thomashow’s assignment using a tree prompts the reader to focus on self framework in ecological identity. I feel that my work and study in Environmental Science resides on the leaf of the tree. It is obvious to me that the root of this important work has begun years ago with the efforts of environmental archetypes (as Thomashow refers to Thoreau‚ Muir‚ and Carson)(p30). I can clearly relate myself to this analogy since I was originally planning on studying engineering and technology but soon realized

Ecological Succession… 1 Ecological Succession is… • The observed process of change in the species structure of an ecological community over time. • The community begins with relatively few pioneering plants and animals and develops through increasing complexity until it becomes stable or self-perpetuating as a climax community. • Succession occurs in all natural environments. Each environment has a particular name that expresses the nature of their ecological succession: Primary and Secondary

FRQ: Ecology Question Ecological succession from a pioneer community to a climax community is an easy process to understand once you know each step. Ecological succession is the transition in the species composition of a biological community‚ often following ecological disturbance of the community. There are two types of ecological succession‚ primary and secondary. Primary succession is the establishment of a biological community in an area virtually barren of life‚ where there were originally
