1 A paradox of scale One species, perhaps counting 80% ‘unhealthy’ specimens, is healthy enough to oust 1000 other species on 1 new species by evolution per year. Which risk do we count?

2 Two problems only decline of biodiversity bad human health

3 Biodiversity according to the CBS Biobase

4 Naturalis

5 Natural history at Naturalis

6 Division of the Plant Kingdom

7 Floras

8 Types of ecology decreasing human centred approach

9 Environmental science: society and environment Environment according to Udo de HaesEnvironment in technical sense

10 Types of ecology decreasing human centred approach

11 Autecology: population and habitat Gadwall duck (krakeend) 04 Garland Weed Class (eendekroosklasse)
