"Biodiversity or biological diversity is the variety and variability of life on Earth."
Works to protect and maintain the variety of life on Earth, including plant and animal species, genetic diversity, and ecosystem diversity.
Definition of Biodiversity: This topic deals with the basics of what biodiversity is and includes its different components.
Importance of Biodiversity: This topic elucidates the significance of biodiversity in human life, and how it supports ecosystem services like water purification, nutrient cycling, and more.
Threats to Biodiversity: This topic looks into the various factors that are responsible for the loss of biodiversity like habitat degradation, deforestation, climate change, pollution, and overexploitation.
Conservation of Biodiversity: This topic explores various measures that can be taken for biodiversity conservation such as protected areas, habitat restoration, captive breeding, and more.
Endangered Species: This topic discusses the species that are currently on the brink of extinction and the reasons behind their precarious status.
Ecosystem Services: This topic explains the different services offered by ecosystems like pollination, pest control, and more, and how biodiversity supports these services.
Biodiversity Hotspots: This topic deals with the global regions that are considered rich in biodiversity due to their large concentration of endemic species and high degree of threat.
Ecological Footprint: This topic explores the impact of human activities on the environment and how it affects biodiversity and ecosystem services.
Sustainable Development: This topic looks into the concept of sustainability which involves meeting the needs of the present generation while keeping in mind the needs of future generations.
Biodiversity and Climate Change: This topic explains the relationship between biodiversity and climate change, and how the loss of biodiversity is linked to the increase in global temperatures.
Indigenous Knowledge: This topic looks into the traditional knowledge and practices of indigenous communities regarding biodiversity conservation and management.
Biodiversity and Food Security: This topic elucidates the role of biodiversity in food production and the potential of biodiversity loss to threaten food security.
Citizen Science: This topic explores the involvement of the public in biodiversity research and monitoring, and their contribution to biodiversity conservation.
Bioprospecting: This topic looks into the use of biodiversity for commercial purposes, and the ethical concerns regarding the exploitation of natural resources.
Biodiversity and Health: This topic explains the link between biodiversity and human health, and how the loss of biodiversity can lead to the emergence of zoonotic diseases.
Eco-tourism: This topic explores the concept of eco-tourism, which involves sustainable tourism activities that support the conservation of biodiversity and local communities.
Marine Biodiversity: This topic elucidates the diversity of marine life and the different threats and conservation measures for marine biodiversity.
Genetic Diversity: This topic looks into the genetic differences among species and populations, and how genetic diversity affects the resilience and adaptability of species in changing environments.
Invasive Species: This topic explains the problems caused by invasive species and the different strategies used to manage these species.
Biodiversity Education: This topic deals with the importance of biodiversity education and the need to raise awareness among children and adults about biodiversity conservation.
Genetic Biodiversity: Variation of genes within species populations.
Species Biodiversity: Diversity between different species.
Ecosystem Biodiversity: Diversity of ecosystems at different levels (from the smallest to largest).
Landscape Biodiversity: Composition and structure of landscapes, which in term affect the composition of the ecosystems.
Behavioural Biodiversity: Variety of behaviours found within and between species as a result of environmental adaptation, social interactions or instincts.
Chemical Biodiversity: Diversity of biochemicals found in nature.
Historical Biodiversity: The diversity in the evolutionary/ ecological history of biodiversity.
Thermal Biodiversity: Diversity of thermal niches for ecosystems and their components.
Competitive Biodiversity: The nature of competition that takes place within and between species.
Community Biodiversity: The diversity of communities with respect to co-existing species.
"Biodiversity is a measure of variation at the genetic (genetic variability), species (species diversity), and ecosystem (ecosystem diversity) level."
"It is usually greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator."
"Tropical forest ecosystems cover less than 10% of Earth's surface."
"Marine biodiversity is usually higher along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans."
"Yes, there are latitudinal gradients in species diversity."
"Biodiversity generally tends to cluster in hotspots."
"More than 99.9% of all species that ever lived on Earth, amounting to over five billion species, are estimated to be extinct."
"About 1.2 million have been documented."
"The total amount of related DNA base pairs on Earth is estimated at 5.0 x 10^37."
"The age of Earth is about 4.54 billion years."
"The earliest undisputed evidence of life dates at least from 3.7 billion years ago."
"There are microbial mat fossils found in 3.48 billion-year-old sandstone discovered in Western Australia."
"Other early physical evidence of a biogenic substance is graphite in 3.7 billion-year-old meta-sedimentary rocks discovered in Western Greenland."
"More recently, in 2015, 'remains of biotic life' were found in 4.1 billion-year-old rocks in Western Australia."
"Since life began on Earth, five major mass extinctions and several minor events have led to large and sudden drops in biodiversity."
"The Cretaceous–Paleogene extinction event, occurred 65 million years ago and has often attracted more attention than others because it resulted in the extinction of the non-avian dinosaurs."
"The ongoing global biodiversity crisis not only involves biological extinctions but also the loss of experience and the gradual fading of cultural knowledge and collective memory of species. The reduction is caused primarily by human impacts, particularly habitat destruction."
"Biodiversity positively impacts human health in many ways."
"A few negative effects are studied."
