Entire unit of work for Environmental systems and societies topic 1.3: energy and equilibria. Full lessons ready to teach: no extra planning needed. Covers: The first law of thermodynamics is the principle of conservation of energy, which states that energy in an isolated system can be transformed but cannot be created or destroyed. • The principle of conservation of energy can be modelled by the energy transformations along food chains and energy production systems. • The second law of thermodynamics states that the entropy of a system increases over time. Entropy is a measure of the amount of disorder in a system. An increase in entropy arising from energy transformations reduces the energy available to do work. • The second law of thermodynamics explains the in efficiency and decrease in available energy along a food chain and energy generation systems. • As an open system, an ecosystem will normally exist in a stable equilibrium, either in a steady-state equilibrium or in one developing over time (for example, succession), and maintained by stabilizing negative feedback loops. • Negative feedback loops (stabilizing) occur when the output of a process inhibits or reverses the operation of the same process in such a way as to reduce change—it counteracts deviation. • Positive feedback loops (destabilizing) will tend to amplify changes and drive the system towards a tipping point where a new equilibrium is adopted. • The resilience of a system, ecological or social, refers to its tendency to avoid such tipping points and maintain stability. • Diversity and the size of storages within systems can contribute to their resilience and affect their speed of response to change (time lags). • Humans can affect the resilience of systems through reducing these storages and diversity. • The delays involved in feedback loops make it difficult to predict tipping points and add to the complexity of modelling systems.

Carrying capacity is the maximum number of a species, or “load” that can be sustainably supported by a given area. It is possible to estimate the carrying capacity of an environment for a given species; however, this is problematic in the case of human populations for a number of reasons. An EF is the area of land and water required to support a defined human population at a given standard of living. The measure of an EF takes into account the area required to provide all the resources needed by the population, and the assimilation of all wastes. EF is a model used to estimate the demands that human populations place on the environment. EFs may vary significantly by country and by individual and include aspects such as lifestyle choices (EVS), productivity of food production systems, land use and industry. If the EF of a human population is greater than the land area available to it, this indicates that the population is unsustainable and exceeds the carrying capacity of that area. Degradation of the environment, together with the consumption of finite resources, is expected to limit human population growth. If human populations do not live sustainably, they will exceed carrying capacity and risk collapse.

Full lessons for IB ESS topic 1: ready to pick up and teach - no extra planning needed. Covers: • Signifcant historical infuences on the development of the environmental movement have come from literature, the media, major environmental disasters, international agreements and technological developments. • An EVS is a worldview or paradigm that shapes the way an individual, or group of people, perceives and evaluates environmental issues, infuenced by cultural, religious, economic and sociopolitical contexts. • An EVS might be considered as a system in the sense that it may be infuenced by education, experience, culture and media (inputs), and involves a set of interrelated premises, values and arguments that can generate consistent decisions and evaluations (outputs). • There is a spectrum of EVSs, from ecocentric through anthropocentric to technocentric value systems.

Entire planned unit of work for Environmental systems and societies, ready to pick up and teach - no extra planning needed. Covers: Demographic tools for quantifying human population include crude birth rate (CBR), crude death rate (CDR), total fertility rate (TFR), doubling time (DT) and natural increase rate (NIR). • Global human population has followed a rapid growth curve, but there is uncertainty as to how this may be changing. • As the human population grows, increased stress is placed on all of the Earth’s systems. • Age–gender pyramids and demographic transition models (DTM) can be useful in the prediction of human population growth. The DTM is a model that shows how a population transitions from a pre-industrial stage with high CBRs and CDRs to an economically advanced stage with low or declining CBRs and low CDRs. • Infuences on human population dynamics include cultural, historical, religious, social, political and economic factors. • National and international develo
