Desertification
• Desertification is the conversion of grassland and savanna habitat into relatively sparse, unproductive vegetation
• The main cause of desertification is overgrazing by livestock

Wetlands
• Wetlands are lands that are transitional between aquatic and terrestrial ecosystems

Wetland Loss
• In the US – the lower 48 states once had about 221 million acres of wetland; today only 95 million acres of wetland remain
• In the US we lose about 200,000 to 400,000 acres of wetlands each year – despite wetlands being protected

Commercial exploitation• Potential market for wild products is enormous• Given market, people will exploit wild species for
financial gain• Domestic substitutes for wild products are not
identical in value• Market price for wild products increases as product
becomes rarer• Wild resources are communal resources owned by no
one or everyone
