Before looking deeper into the loss of biodiversity and its impacts, let us first understand what biodiversity really means. Meaning (What is Biodiversity) Biodiversity refers to the variety and variability of life on Earth. It includes the number of plants, animals, and microorganisms from the Earth’s vastly different ecosystems such as coral reefs, grasslands, tundra, polar ice caps, deserts and rainforests. According to the United Nations Environment Programme (UNEP), variation in biodiversity is typically measured at three levels namely the genetic, the species, and the ecosystem level. Biodiversity is not evenly distributed on the planet and is richest in the tropics. The tropical forest ecosystems contain about 90 percent of the world’s species but cover less than 10 percent of Earth’s surface. Marine biodiversity tends to be highest in areas with high sea surface temperature. Some examples include the mid-latitudinal band in all oceans and the areas along coasts in the Western Pacific. Biodiversity generally tends to cluster in hotspots and continuously increasing with time, but possibly to slow down in the future. Importance of Biodiversity Biodiversity is indeed, very important to the well-being of Planet Earth. The importance of healthy ecosystems and rich biodiversity can be underscored by the following points. • Increase ecosystem productivity – Each species in an ecosystem has a specific role to play. Most of these are interdependent on each other for their su...

Loss of Biodiversity: A decline in biodiversity within a species, an ecosystem, a certain geographic area, or the entire Earth as a whole is known asa loss of biodiversity.Biodiversity means a variety of living organisms found within a geographic region. So, loss in biodiversity means a gradual decline in the variety of species, genetic variability, and the biological components in the surrounding environment. This loss shows a descending impact on the functions of the ecosystem. Some of the major threats to biodiversity are population increase, deforestation, over exploitation of natural resources, etc. Loss of biodiversity may cause decline in plant production in an area, lowered resistance to environmental perturbations, and so on. Read on to learn more interesting facts about loss of biodiversity. Loss of Biodiversity Definition Loss of biodiversity or biodiversity loss means the extinction of species worldwide and loss of different animal and plant species from a particular geographic location or region. What Are the Causes Loss of Biodiversity? Loss of Biodiversity is caused due to: • Increase in Population: We know that our planet’s major part is covered by water and forests. However, an increase in the human population has negatively impacted the ecosystem because of the use of forest land for excessive agriculture and construction by deforestation. It is also found that nowadays, many natural water bodies are covered with soil to make rugged land for construction ...
