Outline  The Relationship of Humans to Their Environment The Effect Humans Have on the Environment Human and Animal Dependence on Plants  Botany as a Science Scientific Method  Diversification of Plant Study (Botanical Disciplines)

The Effect Humans Have on the Environment  Human population will exceed 7.8 billion in 2025– Is the size of the earth increasing?  Major Human impacts on the Environment: Wetlands: Natural vegetation: Dumped: Used chemicals:

The Effect Humans Have on the Environment  We must reduce our environmental impact: Agricultural practices Pollutants Recycle Replace pesticides: Conserve: Habitats and species:

Botany as a Science  Botany =  Science involves:  The scientific method =  Hypothesis =

Scientific Method  Observation and Questioning  Develop Hypothesis  Test Hypothesis Speciments – Experimental Group – Control Group Types of Tests o True Experiments – Observational Studies

Scientific Method …  Test Hypothesis … Types of Variables – Independent Variable – Dependent Variable – Other Variables held constant Collect Data Results—analyzed data  Conclusions: Was Hypothesis supported or not?

Scientific Method …  Theory  Laws or Principles  Field of Study

Diversification of Plant Study (Botanical Disciplines)  Plant Anatomy & Morphology  Plant Physiology  Plant Taxonomy Describing, naming and classifying plants Cross-section of Magnolia wood

Plant Study– Botanical Disciplines  Plant Geography Plant distributions  Plant Ecology  Genetics  Cell Biology  Economic Botany and Ethnobotany: Practical uses of plants and plant products
