Soil Erosion and Degradation • • Land can be degraded by overuse It takes

Soil Erosion and Degradation • • Land can be degraded by overuse It takes 1000 s of years for soil to form Once degraded it is no longer useful for food production Can be degraded by compaction, erosion & overuse.

Loss of Genetic Diversity

Loss of Genetic Diversity

Loss of Genetic Diversity • The Gene Pool is the total number of genes

Loss of Genetic Diversity • The Gene Pool is the total number of genes available within a population. • The smaller the gene pool, the less likely a population will adapt to change. • Only 30 crops and 14 species of animal make up 90% of food consumed by humans.
