Describe and explain the different factors effecting access to safe drinking water. (10 marks)
Planning and Notes:
* From 1996 – 2006 +/- 1.56 billion people gained access to improved drinking-water sources.
* Today 87% people drink from improved water...
The distribution of the earth’s population across the globe is uneven. The earth contains many different environments with only few parts suitable for human habitation.
Around 70% of the earth’s surface is covered in water, leaving only 30% as land; however within this portion exist many physical features...
has three main branches: Physical human and regional. Physical geography is further subdivided into several other branches namely; Geomorphology, Climatology, Oceanography, soil and biogeography. Human Geography is also subdivided into other branches like, cultural, population, social, economic and political...

Population distribution is how people are dispersed over a given area. Population distribution is measured by persons per square kilometer. An area (or country) can be densely populated, which means there is a high concentration of persons per square kilometer, or sparsely populated, which means there...

Biodiversity, Species Interactions, and Population Control
1. Two major factors affect the number of species in a community: the latitude in terrestrial communities and salinity/nutrients in aquatic systems.
2. Species play different roles in a community. Native species...
Poverty in India
Poverty is one of the major problems in India. It is the root cause of many socio-economic problems including population explosion, unemployment, and child labour and rising graph of crimes. Poverty alleviation should be the main target of the nation so as to make it...
improves the nation’s security and creates jobs for Australians
Future Challenges – Population:
* Density of Australia is low, about 2 people for every km2
* Growth rate is 1.9%
* Factors affecting population growth rate include
* Fertility rate- number of children born
Poverty and income distribution in Asian countries
Almost half of the world, that is, three billion people lives on less than $2.50 a day and at least half of the humanity lives in countries where income disparities are present.[Anup Shah, Poverty facts and stats] If we perceive things in a materialistic...
HUMAN RESOURCES AND ECONOMIC DEVELOPMENT
Introduction: we have discussed the role of natural resources in economic development. We have stated that there is a correlation between the availability of natural resources and the level of development in a correlation between the availability of natural resources...

So, what is nutrition? A definition of nutrition is provided and an examination of the factors which influence healthy...

Some say that the pattern of human settlement in Southeast Asia is dispersed settlements where buildings are spread out; an example would be the rural areas of Philippines, where different...
landscape. This is an important concept in geography because it symbolizes how humans interact with their surroundings.
Cultural landscape: Fashioning of a natural landscape by a cultural group. This is the essence of how humans interact with nature.
Arithmetic density: The total number of people divided...
Population distribution means the pattern of where people live. World population distribution is uneven. Places which are sparsely populated contain few people. Places which are densely populated contain many people. Sparsely populated places tend to be difficult places to...
Ecology is the scientific study of the interactions between organisms and the environment. Ecologists are determined to explain both the distribution of organisms and their abundance. In addition to its long history as a descriptive science ecology is also a rigorous experimental science. Ecologists...
Planning is Mission – Oriented.
Planning involves the mapping out or charting of activities in such a way that it helps
to satisfy human wants. Thus, planning is goal-directed i.e planning is directed at
achieving a specified goal or a set of goals.
Planning is Future-Oriented...
environmental biology both stem from Darwin’s interest and observations upon the distribution of organisms and how they adapted to their specific environment. Darwin concluded that the environment interacting with populations could cause evolutionary change. We now know that small changes in the ecological...
order to begin this investigation, we determined that the
factors that were to be tested as independent variables were weight, height, and amount of
regular physical activity. We decided that eating breakfast in the morning does not affect
the amount of calories needed during lunch, according to a...
ologyPopulation ecology - Focuses on the factors that influence the population’s size, growth rate, density, and population structure.
Population - Can be defined in many ways, such as age, ethnicity, type of housing, birthplace, and location. It refers to all of the individuals of the same species...

* For example, hawks feeding on field mice kill certain individuals (over ecological time), reducing population size (an ecological effect), altering the gene pool (an evolutionary effect), and selecting for mice with fur color that camouflages them in their...

To assess a health systems performance we need to understand what a good health system is in a particular...

The ocean sustains life on this planet. It impacts all humankind in this global society. It dramatically affects climate systems and makes the earth a hospitable place to live. Coupled to the atmosphere, it continually recycles air and water, purifying them in...
A Local Ecosystem
1. The distribution, diversity and numbers of plants and animals found in ecosystems are determined by biotic and abiotic factors
a) Compare the abiotic characteristics of aquatic and terrestrial environments
- An ecosystem includes...
planet, and water is an absolute requirement of life. On our planet, the most controlling resource is water — not oil or minerals — but water. Its distribution, quantity, availability, and quality are the controls for the development of agriculture, industry, rural, urban, and municipal use. The water-rich...
controlled by climatic factors, habitats by local irregularities of topography. Therefore, distribution of organisms is also determined by these factors.
III. The physical environment controls and otherwise influences the development of the biological community and its population dynamics.

Changing factors in the demographic environment that affect marketing decisions include the shifting age structure of the Canadian population, the changing Canadian family, geographic shifts in population, a better-educated and more white-collar...
deconstructed. When we expand the vision of health beyond the feelings of the individual we begin to recognize how intricate health is and how many factors are of influence. Income, social status and environmental stressors such as global warming all impact our existing and future health. These determinants...
This essay is about the Population Distribution in south east and north Brazil. It describes how uneven populated the different areas of
Brazil are. It includes explanations and reasons in human, physical, economic and social context. Brazil in terms of population distribution is extremely varied and...
Distinguish among organismal ecology, population ecology, community ecology, ecosystem ecology, and landscape ecology.
5. Clarify the difference between ecology and environmentalism.
Interactions between Organisms and the Environment Limit the Distribution of Species
6. Define biogeography.
