What is biodiversity its need and importance and importance of biodiversity and the cause of loss of biodiversity?
Biodiversity is the natural world around us, and the variety of all of the different kinds of organisms - the plants, animals, insects and microorganisms that live on our planet. Every one of these live and work together in ecosystems to maintain and support life on earth, and exist in delicate balance.Biodiversity includes the number of different organisms and their relative frequencies in an ecosystem. It also reflects the organization of organisms at different levels. Biodiversity holds ecological and economic significance. It provides us with nourishment, housing, fuel, clothing and several other resources. Biodiversity maintains the ecological balance. It helps in the healthy existence of humans and other species in the ecosystem. It helps in high productivity and human wellness. Biodiversity provides humans with valuable genetic diversity. Biodiversity helps in pollination, nutrient cycling as well as recycling, greenhouse gas reduction by sequestration. Social and cultural services: Biodiversity provides us with aesthetic pleasure. It provides recreational avenues and rich biological diversity encourages tourism in the region. Biodiversity helps in sensing how life functions and the role of each species in sustaining ecosystems. The level of biodiversity is a good indicator of the state of the relationships of human beings with other living species.Biodiversity, or the variety of all living things on our planet, has been declining at an alarming rate in recent years, mainly due to human activities, such as land use changes, pollution and climate change. Biodiversity is the presence of a variety of life on earth. It can be measured on three levels: genetic, species and ecosystem level. Other main causes of biodiversity: The loss of habitat will result in fragmentation of habitat leading to small habitat with few organisms.Biodiversity refers to the variety of organisms in an ecosystem. However, the biodiversity of an ecosystem is lost when there is an over exploitation of the available resources, fragmentation of the habitat or invasion by any alien species. The major cause of the decrease in biodiversity is due to the process by which the animal's natural habitat is destroyed which results in the change in habitat, this is called habitat destruction or habitat loss. Additional information: -Biodiversity is the presence of a variety of life on earth. The main direct cause of biodiversity loss is land use change which drives an estimated 30% of biodiversity decline globally.
