wildlife requires an understanding of the relationships between
different organisms and their environment. This idea forms the crux
of ecology. Ecology examines how organisms interact with one another
and their environment. Ecology can be divided into different levels
For the purpose
of understanding wildlife, we shall look closely at ecosystems,
communities and populations. The study of individual organisms is
left to biology, and remains crucial to this purpose. The ecosphere
itself can be understood as a large, complex organism whose many
organs consist of interconnected ecosystems. Such a large system
is quite difficult to examine as one thing. The ecosphere is applicable
to wildlife concerns when it comes to the debate on extinction.
One side of the debate argues that there is an international wildlife
crisis currently in the world, whereas the other side disclaims
any such possibility.
