1. Specific characteristics of anthropogenic factor
Anthropogenic factor – a factor that is caused by human activity. Specific characteristics of an anthropogenic factor:
• Irregular – affect on organisms spontaneously
• Unpredicted – affect on organisms at a higher rate - organisms cannot adapt. • Unlimited – effect on organisms up to utter destruction: (compare with natural disasters!). • Changes of environment – affect organisms through change of climate, temperature, moisture, light, pollutants. • Negative effect for themselves – affect humans as species and other organisms (principle of “ecological boomerang”) • Creation of social factors – affect people via TV, psychological stress, education, living conditions etc. Scheme: An overview of the ecological issues
