Why is biodiversity important to humans?
Biodiversity is important in a number of ways to humans. First, biodiversity has a direct impact on people by providing food, fuel, and medicine. Second , biodiversity can have indirect impacts via an ecosystem’s sustainable function or provision of services such as flood regulation, soil formation, and nutrient recycling that are critical for human life support.
What Is Biodiversity?
Biodiversity is a term that “refers to the variety and variability among living organisms from all sources including terrestrial, marine, and other aquatic ecosystems”. In simpler terms, it is the variation of life on Earth. The conservation of biodiversity has been a major topic since at least 1982 when it was included in Agenda 21, a non-binding international agreement regarding sustainable development at the United Nations Conference on Environment and Development. More recently, a major effort to measure sustainability is basically “a way of measuring the health of the planet”.
How Is Biodiversity Measured?
Biodiversity may be measured as the number of different species or genetic varieties in a given area or environment. Ecosystems are composed of dynamically interacting physical, chemical, geological, hydrological, and biological processes forming an integrated whole that can not be understood apart from its parts.

Biodiversity in simple words defined as all forms of life that exist on planet Earth. This can be also defined as the measure of variation at the genetic, species, and ecosystem level. Biodiversity is responsible for the air we breathe, the water we drink and teh food we eat. The future of humanity depends on biodiversity.
What is Genetic diversity?
Genetic diversity is the amount if variation we can see in particular species or among a set of population. Scientist and researcher see a high level of diversity among different species, howvever, genes there can be more variations we can see in the species. The best example of genetic biodiversity can be the variation in genes that is responsible for hair colour in humans.
What is ecological diversity?
Ecological diversity is the variation we can see on the entire planet. This includes variation in both terrestrial and aquatic ecosystems. We will also study ecological diversity to study variation in the complexity of a biological community in different niches and also a number of trophic levels and other ecological processes. The example includes variation in deserts, forests, grasslands, wetlands and oceans. This is the largest scale of biodiversity and within each set of the ecosystem, there is both species and genetic diversity.
What is the definition of biodiversity?

The term biodiversity was introduced by Walter Rosen (1986). Biodiversity is the assemblage of different life forms. Each species is adapted to live in its specific environments. The changes in climatic conditions are reflected in the distribution and pattern of biodiversity on our planet.
What are the factors that determine biodiversity distribution patterns?
Temperature, precipitation, distance from the equator (latitudinal gradient), altitude from sea level (altitudinal gradient) are some of the factors that determine biodiversity distribution patterns. The most important pattern of biodiversity is latitudinal gradient in diversity. This means that there is an increasing diversity from the poles to equator.
