What are the 5 main causes of biodiversity?
Biodiversity loss is caused by five primary drivers: habitat loss, invasive species, overexploitation (extreme hunting and fishing pressure), pollution, climate change associated with global warming.
What are effects of biodiversity?
Even though only a minority of humans realize it, biodiversity provides humans with food, water, oxygen, energy, detoxification of waste, stabilization of earth’s climate, medicine, opportunities for recreation and tourism, and many more things (Secretariat, 2000).
What are the 5 threats to biodiversity?
Five main threats to biodiversity are commonly recognized in the programmes of work of the Convention: invasive alien species, climate change, nutrient loading and pollution, habitat change, and overexploitation.
What are the causes and effects of biodiversity?
Habitat destruction Habitat destruction is a major cause of biodiversity loss. Habitat loss is caused by deforestation, overpopulation, pollution, and global warming. Species that are physically large and those living in forests or oceans are more affected by habitat reduction.
What are the 6 threats to biodiversity?
Below, we discuss six of the major threats to biodiversity: climate change, habitat loss and degradation, pollution, invasive species, over-exploitation and epidemics.
How do biotic factors affect biodiversity?
The biodiversity in ecosystems is affected by the following three factors: Biotic: Biotic factors are the interactions between the living things in an ecosystem. This can include grazing and predation. Animals which graze on the plant species in an ecosystem can influence which species of plants can survive.
How does light affect biodiversity?
Since sunlight directly impacts primary productivity and thereby, food and nutrient availability, the amount of light hitting the water may affect the biotic composition of a stream (Cushing & Allan 2001). As such, a range of light intensities would increase overall stream biodiversity.
