The most interesting films made,
mostly for television, are about nature. Some of them only deal with animals
and their lives, such as what kinds of animals live in which part of this
planet. Then, the origin of their lives and their habitats are discussed in
detail. Some other nature films are about plants in different regions of the world,
and how climate change affects production, growth, development, and survival of
such living organisms. Another series of these films deal with the formation of
our world, and how this world came about several million years ago. In addition,
the time of the first living organisms, and appearance and extinction of some
of these organisms are discussed.
