Brief summary of conservation of forests &amp; wildlife <br><br> least 10 page
wel

With the advent of industrialization, several trees have been cut at an alarming rate for raw materials and various other purposes. This felling of trees can be regulated by selective cutting, clear-cutting and shelterwood cutting.

Forest fires are one of the common causes of loss of forests. Sometimes the forest land is set on fire to make the land available for commercial purposes. Once cleared, there can be no vegetation. Natural forest fires are also responsible for the destruction of huge forest covers. Latest fire fighting techniques should be adopted to conserve the forest. However, forest fires are an important part of the ecosystem and it helps replenish nutrients in the soil from dead and decaying matter.

More trees should be planted to increase the forest cover. Trees should be selected according to the geographical conditions of a particular region and proper care should be taken during the growth of trees.

Prevention of exploitation of forestry and forest products is necessary for the conservation of forest.

The existing forests should be protected from diseases by spraying chemicals, antibiotics or development of pest-resistant strains of trees.

Elza [17]

"Dave", the feathered lizard fossil is thought of as a(n)<u> </u><u>homologous</u> species, or an organism that may represent a common ancestor shared by different but related lineages of organisms.

<h3>What is homologous evolution?</h3>

Homologous evolution is similarity of the structure, physiology, or development of different species of organisms based upon their descent from a common evolutionary ancestor.

Homologous structures include the human arm, a bird or bat's wing, a dog's leg, a dolphin or whale's flipper, and the wing of a bird or a bat. They are distinct and serve different purposes, although they are comparable and have similar characteristics. They are regarded as homologous structures because their underlying anatomies are comparable.
