Diversity affects the amount of resources we can use sustainably, because it influences ecosystem health, resilience and productivity. Taking too much from an ecosystem decreases diversity and sustainability.
Diversity (or biodiversity) is the variation within and between living things. It is measured on many levels; from genetic variation to differences between individuals within populations to differences among species and among ecosystems.
Ecosystems supply us with resources we need; like food and water, building materials, medicine, cultural benefits, and income. However, the global level of diversity has fallen by 27% over the last 35 years. This means that we are losing resources because of the strong effect that diversity has on productivity. Maintaining ecosystem sustainability is the only way we can guarantee a continued supply of resources.
Diversity is important to sustainability in 3 main ways:
At present, technology is unable to replicate most of these services, but ecosystem services are free if the diversity of an ecosystem is maintained.
Diversity is a key element of sustainability due to its effect on productivity, resilience, and preserving quality of life. Preventing diversity loss is crucial in preserving a sustainable ecosystem.
