FINITENESS OF RESOURCES FINITE Having limits or bounds, completely determinable in theory or in fact by counting or measurement. RESOURCES Is a source or supply from which a benefit is produced and that has some utility. Classified as renewable and non-renewable. MINING Is a process of mineral extraction from the surface of the Earth either from land or from the seas. MINERALS Are inorganic substances occurring in nature that has a definite chemical composition and distinct physical properties. It is important in the production of products required by humans. MINERAL DEPOSIT Are naturally occurring accumulations or concentrations of metals or minerals of sufficient size and concentration that might (under favorable circumstances, have economic value). ORE A naturally occurring solid material from which a metal or valuable mineral can be profitably extracted. Impacts of Mining FOSSIL Are the preserved remains, or traces of remains, of ancient organisms. FOSSIL FUEL Are hydrocarbons, primarily coal, fuel oil or natural gas, formed from the remains of dead plants and animals. Impact of fossil fuel depletion DEFORESTATION Is the permanent removal of trees to make room for something besides forest. Include clearing the land for agriculture or grazing, or using the timber for fuel, construction or manufacturing. IMPORTANCE OF FOREST ECOSYSTEMS Source of Food Source of raw materials (furniture, clothes, shelter) Climate control and modification Disaster Risk Reduction Source of medicine Tourism value Air and water purification Social and Cultural value Impact of Deforestation OVERFISHING Is the removal of a species of fish from a body of water at a rate that the species cannot replenish, resulting in those species becoming underpopulated in that area. Impact of Overfishing  POVERTY, HUNGER AND THREATS TO FOOD SECURITY POVERTY Is a deprivation of one’s basic needs due to lack of money to buy services or lack of access to services. A key contributory factor to hunger.  Global Hunger Index (GHI) Indicators Undernourishment: the share of the population that is undernourished (caloric intake is insufficient) Child wasting: the share of children under the age of five who are wasted (have low weight for their height; acute undernutrition) Child stunting: the share of children under the age of five who are stunted (who have low height for their age; chronic undernutrition) Child mortality: the mortality rate of children under the age of five FOOD SECURITY Is a measure of the availability of food and individuals' ability to access it. Affordability and nutrition are some factors. The availability of food irrespective of class, gender or region is another one.  THREATS TO FOOD SECURITY Population growth Increase demand for food Food price The disappearance of the variety of agricultural plant species. The increase in the area of scarcity water and the limitation of the availability of land. The food losses and food waste (lack of adequate infrastructure for food production).
