Significant Ideas: A systems approach can help in the study of complex environmental issues. crude birth rate. The Environmental Footprint measures the types of products or services provided by the global hectares, for example, in terms of goods from crop lands, animal products, fish, forest products, built up areas, and energy and water use. Resource requirements vary according to lifestyles, which differ from time to time and from population to population. For a given region, carrying capacity is the maximum number of individuals of a given species that an area's resources can sustain indefinitely without significantly depleting or degrading those resources. Limiting … Try to compare and contrast the EF of two countries while exploring how the EF is calculated for both. Created by. For a given region, carrying capacity is the maximum number of individuals of a given species that an area's resources can sustain indefinitely without significantly depleting or degrading those resources. If being alive on Earth were a contest, humans would win it hands down. Human carrying capacity is difficult to quantify and contains elements of subjective judgment. The first idea of carrying capacity applied to natural organisms was introduced in the 1980’s so the concept that the earth is a ship with only enough food and resources to be able to sustain a finite population is not new (Sayre 2007). 3.1.3 Analyse age/sex pyramids… Crude birth rate # of births per 1000 individuals in a population per year .

It is essential to use key terms correctly when communicating your understanding, particularly in assessments. Significant ideas: Human carrying capacity is difficult to quantify. IB ECON & ESS PROJECT * The New Peace Index. TOPIC 3: Human Population Growth, Carrying Capacity, & Resources . For example: image from http://pthbb.org/natural/footprint/, Clearly, human numbers can not continue to increase indefinitely. Match. An organism’s niche is its role within an ecosystem including all interactions with other organisms as well as with the non-living aspects of the environment. PLAY. Explain how the EF is used to estimate the demands that human populations place on the environment. Start studying ESS 8.4 Human population carrying capacity. Such analyses identify which areas are placing the greatest strains on ecosystems, and can help set policy priorities. 3.1.2 Calculate and explain, from given data, the values of crude birth rate, crude death rate, fertility, doubling time and natural increase rate.

Terms in this set (49) exponential growth. Increase in EF with each stage of the DTM, Energy use much greater in later stages of the DTM, Greater wealth leads to higher consumption of goods and natural resources such as water, More use of transportation in stages 4 & 5, Increased industrialization and pollutants in stage 3, Discuss the link between the EF and sustainability, Explain how humans can cause the total collapse of environmental life support systems through environmental degradation and excessive consumption of resources., Technological development changes resources required and available for consumption, Try to cover each of the areas of the EF: Cropland & Footprint, Grazing & Footprint, Forest & Footprint, Fishing Ground & Footprint, Carbon Footprint, and Built-up Land. Carrying capacity is the maximum number of a species, or “load”, that can be sustainably supported by a given area. Carrying capacity has become arguably the most important concept in the era of Anthropocene. It may be possible to increase our carrying capacity. Carrying capacity is the maximum population size that the environment can support without deterioration (McGraw-Hill, 2002). While importing resources in this way increases the carrying capacity for the local population, it has no influence on global carrying capacity. Flashcards. The why: The study of carrying capacity makes it easy to use many of the most highly-effective teaching strategies. Spell. Technocentric – human carrying capacity can be expanded continuously through technological innovation and development. Today Hank is here to tell us the specifics of why and how human population growth has happened over the past hundred and fifty years or so, and how those specifics relate to ecology. The main factors are temperature and water availability. Population Theorists: Malthus and Boserup, It's time environmentalists talked about the population problem, Fossil Fuels Are Biggest Part of Global Ecological Footprint, Creative Commons Attribution-ShareAlike 4.0 International License, Human carrying capacity is difficult to quantify. In this unit we will look at how human populations regularly import resources from outside their immediate environment, which enables them to grow beyond the boundaries set by their local resources and increases their carrying capacity. Determining the carrying capacities for most organisms is fairly straightforward. Determining the carrying capacities for most organisms is fairly straightforward. growth rate which is increasingly rapid or an accelerating rate of growth. PLAY. Welcome to IB Standard Level ESS The Environmental Systems & Societies (ESS) course is an interdisciplinary course which is unique in that it contains various sciences, coupled with a societal viewpoint, all intertwined to help you understand the environment and its sustainability. For humans carrying capacity is much more complicated. Growth in animal products and energy use, especially of fossil fuels, are two areas that are rapidly increasing these strains. 3.2 Resources – Natural Capital. increased use of technology and energy (but technology can also reduce the footprint), high levels of imported resources (which have high transport costs), large per capita production of carbon waste (high energy use, fossil fuel use), transporting waste to other countries to deal with, improving country to increase carrying capacity, reducing population to reduce resource use, using technology to increase carrying capacity. Bio-productive land: land used for food and materials, Bio-productive sea: sea area used for human consumption, Energy land: land required to support renewable energy instead of non-renewable energy, Built land: land that is used for development of roads and buildings, Biodiversity land: land required to support non-human species. All these variables make it practically impossible to make reliable estimates of carrying capacities for human populations. STUDY. resource booklet. A crucial concept in assessing the presence and consequences of pressure on the land is the concept of carrying capacities. Conventional Economists – trade … David Suzuki speaks about world populations and how growth, is ultimately suicidal. Your results, with correct answers, will be sent to the email address you submit.

PLAY. ESS Chapter 2. One of the consequences of this explosive growth in human numbers is that human demands have outrun the carrying capacity of the economy’s natural support systems — its forests, fisheries, grasslands, aquifers, and soils. More. Write. The definition is expanded to include not degrading our cultural and social environments and not harming the physical environment in ways that would adversely affect future generations. When the global population reaches 9 billion people, how will the Earth cope? Carrying capacity, the average population density or population size of a species below which its numbers tend to increase and above which its numbers tend to decrease because of shortages of resources. An ecosystem’s carrying capacity for a particular species may be influenced by many factors, such as the ability to regenerate the food, water, atmosphere, or … Topic 3: Human population, carrying capacity and resource use (39 hours) 3.1 Population dynamics 3.1.1 Describe the nature and explain the implications of exponential growth in human populations. ESS Home: IB Chemistry: IB Environmental Systems & Societies: Mrs. image from http://lifeboat.com/images/carrying.capacity.of.earth.jp, The range of resources used by humans is usually much greater than for any other species, When one resource becomes limiting, humans show great ingenuity in substituting one resource for. Ecological economists say that this is not so and that technological innovation cay only increase the efficiency with which natural capital is used. Avec un nom féminin, l'adjectif s'accorde. Gravity. those factors which affect organisms in their ecosystems and are non-living, physical and chemical components (soil salinity, pH, temperature, insolation levels or precipitation) fundamental niche. carrying capacity n noun: Refers to person, place, thing, quality, etc. Learn. This will help you to answer the any EF related question but also allow you to have a more holistic picture of the topic, better understand the resource booklet structure and prepare you for the exam. Technological developments give rise to continual changes in the resources required and available for consumption. Explain the concept of carrying capacity. While importing resources in this way increases the carrying capacity for the local population, it has no influence on global carrying capacity. 3.3 Energy Resources * 3.4 The Soil System * 3.5 Food Resources * 3.6 Water Resources * 3.7 Limits to Growth. Carrying capacity is the number of organisms that an ecosystem can sustainably support. Consolidate this by developing 5 questions that would correspond to the resource booklet. More than 3 billion people worldwide are already malnourished, and 3 billion are living in poverty; grain production per capita started declining in 1984 and continues to decline; irrigation per capita declined starting in 1978 and continues; arable land per capita declined starting in 1948 and continues; fish production per capita started declining in 1980 and continues; fertilizer supplies essential for food production started declining in 1989 and continues to do so; loss of food to pests has not decreased below 50% since 1990; and pollution of water, air, and land has increased, resulting in a rapid increase in the number of humans suffering from serious, pollution-related diseases, image from Center for Immigration Studies.
