Biodiversity which is rich in positive things for creatures and the environment

 The definition of biodiversity is the diversity among living things from various sources.  This includes the interaction of terrestrial, coastal, oceanic ecosystems, other aquatic ecosystems and ecological complexes in which various living things are part of it.

 -Understanding Biodiversity

 Biodiversity includes the diversity of biological resources at the level of genes, species and ecosystems.  That is the meaning of biodiversity according to the Convention on Biological Diversity (1993).

 1. Biodiversity at the gene level

 Gene level biodiversity.  Is the genetic variation within a species, both between geographically separated populations and between individuals in a population.  Individuals in a population have genetic differences from one another.  The level of gene diversity arises because each individual has unique gene forms.  Genetic variation increases when offspring receive a unique combination of genes and chromosomes from the parent through gene recombination that occurs through sexual reproduction.  It is this process that increases the potential for genetic variation by randomly rearranging alleles so that different combinations arise.

 2. Ecosystem level biodiversity

 Ecosystem-level biodiversity is a distinct biological community and its association with their respective physical environments.

 3. Species level biodiversity

 Species diversity includes all species found on earth, both plants and wildlife.  This includes bacteria and protists as well as species from the multicellular kingdom such as plants, fungi, animals.  A species can be defined as a group of individuals who exhibit several important characteristics that are different from other groups.  These characteristics can be morphological, physiological or biochemical.  This morphological definition of species is most widely used by taxonomists.  They specialize in classifying and identifying unknown specimens.

 The benefits of biological diversity for humans and the environment include:

 1. Increase the productivity of the ecosystem in which each species is present.  No matter how small, all have an important role in the ecosystem.  For example, the large number of plant species means that it has many medicinal potentials, reduces the impact of climate change, a source of food.

 2. Large species diversity ensures the sustainability of nature to support all forms of ecosystem life.  It also plays a role in reducing the risk of various natural disasters such as mangroves in preventing abrasion and tsunamis.

 3. Indonesia's rainforest ecosystem is rich in species diversity.  The loss of mangrove forests will also have a negative impact because it is the same as eliminating the benefits of mangroves.

 4. Properly managed natural resources will increase the benefits of nature for human health.

 5.Good biodiversity provides a number of natural environmental services to humans.  This includes protection of water resources, protection of land from landslides and floods, storage of nutrients (nutrients).  Biological resources also play a role in absorbing environmental pollutants such as CO2, maintaining climate stability, maintaining ecosystem balance.  It also provides food, medicinal sources and pharmaceutical drugs (medicinal plants), ornamental plants, fish spawning, research, education, and nature tourism.  All of this is obtained free of charge from nature.
