Key messages ✽ ✽ Biodiversity is the term used to encompass the variety of all living organisms on earth , including their genetic diversity, species diversity and the diversity of marine, terrestrial and aquatic ecosystems, together with their associated evolutionary and ecological processes.
What is biodiversity in PDF?
Abstract. Biodiversity is the variety of different forms of life on earth , including the different plants, animals, micro-organisms, the genes they contain and the ecosystem they form. It refers to genetic variation, ecosystem variation, species variation (number of species) within an area, biome or planet.
What is biodiversity and what is its importance?
Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services . Recreation—many recreational pursuits rely on our unique biodiversity , such as birdwatching, hiking, camping and fishing.

What is biodiversity and why it is important for human life?
Biodiversity plays a crucial role in human nutrition through its influence on world food production , as it ensures the sustainable productivity of soils and provides the genetic resources for all crops, livestock, and marine species harvested for food.
What are 5 benefits of biodiversity?
Support a larger number of plant species and, therefore, a greater variety of crops. Protect freshwater resources. Promote soils formation and protection . Provide for nutrient storage and recycling.
Why biodiversity is so important?
Biodiversity provides vital ecosystem functions such as soil fertilization, nutrient recycling, pest and disease regulation, erosion control and crop and tree pollination.

How do humans benefit from biodiversity?
Humans depend upon biodiversity for survival , such as for the foods we eat, medicines we use to stay healthy, and materials we wear or use to build our homes. These services are the tangible products or items that we and other species con sume for survival.
Why do we need to protect biodiversity?
Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. ... Biodiversity is the key indicator of the health of an ecosystem . A wide variety of species will cope better with threats than a limited number of them in large populations.

What are the 5 major causes of biodiversity loss?
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 the negative effects of biodiversity?
The main threats facing biodiversity globally are: destruction, degradation and fragmentation of habitats . reduction of individual survival and reproductive rates through exploitation , pollution and introduction of alien species.
What are the causes and effects of biodiversity loss?
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.
