HUMANS IN THE BIOSPHERE 5.03 Assess human population and its impact on local ecosystems and global environments: Resource use. Sustainable practices/stewardship.
Hunting and gathering Agriculture Industry Urban development Human Activities
Renewable = regenerate if alive, if nonliving renew by cycles. Ex: water in the water cycle Nonrenewable = cannot be renewed by natural processes. Ex. oil II. Classifying Resources
Way of using natural resources without depleting them. Provide for human needs without hurting the environment III. Sustainable development
Is renewable If mismanaged can lead to damages: such as erosion and desertification. wearing away of good land turns into soil desert due to overgrazing, drought IV. Land Resources
Contour plowing Leaving stems/roots of harvested crops Planting with cover crops between crops V. Sustainable Practice
Called the “Lungs of the Earth” Why? Job: store nutrients, provide habitats, limit soil erosion, etc. VI. Forest Resources
Is renewable depending on type of forest: temperate forest = renewable old growth forest = nonrenewable Deforestation = is the loss of forest Can cause soil erosion
Only harvest mature trees Replant after harvesting Genetically produce faster growing trees A. Sustainable Practices
Renewable if managed properly Human effects = over fishing Benefits = cheap source of protein VII. Fishery
Regulate fish size, quantity and season for harvesting Promote Aquaculture = raising of seafood for human consumption. Ex: shrimp, catfish A. Sustainable Practices
Is renewable Human effects = pollution in the form of smog Benefits = need it to live & keeps our planet warm (greenhouse gases) IX. Air
Reduce car emissions Reduce factory emissions Use filters in smoke stacks of factories A. Sustainable Practices
Used to protect crops Negative effects = kills both good and bad bugs! Use can cause “Biological Magnification”. Is the concentration of a harmful substance as you go up the food chain Pesticides
Conservation (defined) - Preservation or restoration from loss, damage, or neglect Conservation
