Species Extinction- Reasons and Effects?

Species Extinction

• Causes Effects

What do you mean by Species Extinction?

• In biology and ecology, extinction is the
  termination of an organism or of a group of
  organisms normally a species. The moment of
  extinction is generally considered to be the
  death of the last individual of the species,
  although the capacity to breed and recover may
  have been lost before this point.

Types Of Species Extinction?

• Diversity Independent Extinction.
• Diversity Dependent Extinction.
• Mass Extinction.
• Absolute Extinction.
• Pseudo Extinction.

Solutions For Habitat Loss and Destruction

• We can combat habitat loss by preserving natural
  resources and learning how to use them in a way
  that does not require such frequent destruction
  of habitats. Regulation is equally important.
• We should also teach others the importance of
  biodiversity.
•  Along with education, awareness should also be
  raised.
• As quickly as humans can destroy natural
  habitats, we should be just as willing to put
  forth the effort to rebuild and attempt to
  replace what is lost.

What are the possible Consequences?

• There are many consequences if these animals in
  danger of extinction become extinct. Of course,
  the loss of their beauty is very important. But
  beyond beauty, each of these species is part of a
  whole system. If one part of the system is
  removed the system is no longer in balance and
  the stage is set for something else to happen in
  that area.  This can have major effects when all
  the functions of an eco-system are examined.  For
  example, what happens if a pollinator becomes
  extinct? What happens to the prey if a  predator
  becomes extinct?

What Needs to be Done?

• There are many things that can be done to help
  these species, and all the others so they arent
  facing total extinction.  Learn about these
  species and understand why they are important in
  their environment.  Education is very important.
  Understanding how humans can live in harmony with
  all things on Earth is key. Humans are animals
  too if the animals are in trouble and dying,
  what will happen to us?
