A water molecule consists of two atoms of hydrogen linked by covalent bonds to the same atom of oxygen. Atoms of oxygen are electronegative and attract the shared electrons in their covalent bonds.
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.

The existing forests should be protected from diseases by spraying chemicals, antibiotics or development of pest-resistant strains of trees.
The set of Wavelength is absorbed by pigment. So in a typical leaf some pigment can’t be visible.
Explanation:
There are mainly three types of key pigments in photosynthesis. These three key pigments are Chlorophyll a, Chlorophyll b, and β-carotene. Those set of wavelengths which is not absorbed by pigment and finally it is reflected and that reflected light is what we see as a color.
The reason behind color of plant looking green because it contains huge amount of chlorophyll a and b molecule. It reflects the green light.
