Environment 1: Grade 10

Grade 10: Eco Curriculum

GEOGRAPHY

Atmosphere: weather and climate (Context: The World)
■ The atmosphere
• heating of the atmosphere;
• impact of humans on the atmosphere and weather (e.g. the ozone issue, global warming, acid rain, the
greenhouse effect – use case studies from African states);
• deserts: formation, distribution, arid processes and resultant landforms.

People and places: population Context: (The World and Africa)
■ Key foci emphasising spatial distribution, processes and patterns include:
• population movements: rural-urban migration, urbanisation;
• population growth and density;
• population distribution;
• population explosion;
• ageing population;
• population control;
• population policies;
• rural depopulation;
• population characteristics;
• population pyramids.
■ Key human-environment interactions, including:
• population issues and dilemmas including poverty, racism, employment, conflicts, inequalities,
HIV/AIDS and refugees;
• gender issues.

People and their organizations (Context: The World and Africa)
This section emphasises human interactions with the environment that promote democratic processes, social
justice, economic sustainability and peace. It provides opportunities for learners to develop a critical
understanding of unequal distribution patterns and processes over space and time, and the resultant uneven
development. It also introduces learners to processes of democratic dialogue and collaborative action for the
attainment of shared values. Learners are encouraged to develop a common purpose in seeking viable solutions
and appropriate management strategies for addressing inequalities in society and the environment. People
organise themselves for action in different ways.
■ Civic organisations (e.g. local pressure groups, non-governmental organisations).
■ National organisations (e.g. political organisations).
■ Continental organisations (e.g. SADC, NEPAD, AU).
■ Global organisations (e.g. United Nations, multinationals, Oxfam, World Bank).

 

BIODIVERSITY, CHANGE AND CONTINUITY

Biodiversity of plants and animals and their conservation

Introduction
Define the terms biodiversity and conservation
Outline the biodiversity that exists with regard to:
 habitats
 modes of nutrition
 structural adaptations

Significance and value of biodiversity to ecosystem function and human survival

Threats to Biodiversity

Introduction
What is meant by loss of biodiversity
List consequences of a loss in biodiversity

Threats to Energy Relationships and continued provision of humanresources
Discuss any two human activities that may lead to loss of biodiversity such as…
• Habitat Destruction
• Deforestation
• Silviculture/Commercial Forestry
• Poaching and Hunting
• Overfishing
• Traditional medicine/muti-trade
• Introduction of alien species
• Global warming
• Ozone depletion
• Commercial agriculture
• Ranching
• Pollution,
• Dune mining

Preventing threats to biodiversity
Conduct research to find out
• Species that have become extinct
• species that are endangered
• factors that lead to species becoming endangered or becoming extinct
• strategies to prevent extinction (arbor day, world environment day, etc.)
• legislation as a strategy to overcome threats to biodiversity, e.g. legislation controlling fishing, legislation for protected species, legislation over pollution control
