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 at this point.

Species Extinction

Causes & Effects

what do you mean by species extinction
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.
reason for species extinction
Reason for Species Extinction?
  • Deforestation/ Habitat Loss
  • Hunting/Poaching.
  • Over Exploitation.
  • Introduction to Exotic Species.
  • Global Warming.
  • Diseases, Pollution.
types of species extinction
Types Of Species Extinction?
  • Diversity Independent Extinction.
  • Diversity Dependent Extinction.
  • Mass Extinction.
  • Absolute Extinction.
  • Pseudo Extinction.
solutions for habitat loss and destruction
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

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
What Needs to be Done?

There are many things that can be done to help these species, and all the others so they aren’t 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?
