Why Is Biodiversity Important?

Biodiversity is important to most aspects of our lives. We value biodiversity for many reasons, some utilitarian, some intrinsic. This means we value biodiversity both for what it provides to humans, and for the value it has in its own right. Utilitarian values include the many basic needs humans obtain from biodiversity such as food, fuel, shelter, and medicine. Further, ecosystems provide crucial services such as pollination, seed dispersal, climate regulation, water purification, nutrient cycling, and control of agricultural pests. Biodiversity also holds value for potential benefits not yet recognized, such as new medicines and other possible unknown services. Biodiversity has cultural value to humans as well, for spiritual or religious reasons for instance. The intrinsic value of biodiversity refers to its inherent worth, which is independent of its value to anyone or anything else. This is more of a philosophical concept, which can be thought of as the inalienable right to exist. Finally, the value of biodiversity can also be understood through the lens of the relationships we form and strive for with each other and the rest of nature. We may value biodiversity because of how it shapes who we are, our relationships to each other, and social norms. These relational values are part of peoples’ individual or collective sense of wellbeing, responsibility for, and connection with the environment. The different values placed on biodiversity are important because they can influence the conservation decisions people make every day.

Biodiversity is a term which describes every living organism within a single ecosystem or habitat, including numbers and diversity of species and all environmental aspects such as temperature, oxygen and carbon dioxide levels and climate. Biodiversity can be measured globally or in smaller settings, such as ponds.

Why is Biodiversity Important?

How does deforestation affect biodiversity?

Biodiversity also has a role to play in the stability of the ecosystem and global climate. Deforestation removes trees responsible for the conversion of carbon dioxide into oxygen. This increase in carbon dioxide levels in the air is partially (but significantly) responsible for global warming. Deforestation also leads to soil erosion where other species of plant suffer, with the forming of desert-like areas as a result. The domino effect of this means less food for herbivores (primary consumers) and a consequent reduction in populations due to competition. And with fewer herbivores, one can expect reduced populations of omnivores and carnivores. As every organism has a role to play in its ecosystem, the act of deforestation without (at minimum) replanting lost mature trees, can be catastrophic both locally and globally.

How is biodiversity measured?

Ecological biodiversity is measured by looking at its three levels of genetic, species and ecosystem diversity.
