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.

Answer:
B) Any child born of parents who are able to taste PTC will inherit the ability to taste PTC.
Explanation:
The ability to taste the chemical PTC (phenylthiocarbamide) contain some people who can and some people who cannot taste PTC. Despite the fact, this trait is often considered a simple Mendelian trait, i.e.one gene-two alleles.(a simple genetic trait governed by a pair of alleles).The reason why this trait has been kept going in the population is undetermined but polymorphism may influence food selection or nutritional status.
If we have two parents that are heterozygous for this PTC traits, if the cross, they will have the following types of offspring.
Let say; dominant T for tasting and recessive t for nontasting---- i.e Tt
If Tt crosses with Tt, we have;
T t
T TT Tt
t Tt tt
From the punnet square, we have the following offspring
TT (dominant PTC taster )
2 Tt ( heterozygous PTC taster)
tt (recessive Non- taster)
From, the foregoing, we can clearly see that the incorrect statement about the inheritance of the ability to taste the chemical PTC (phenylthiocarbamide) is Any child born of parents who are able to taste PTC will inherit the ability to taste PTC. This is because from the cross, it is not all children that inherit the ability to taste PTC.
