Many plant and animal species are on the verge of their extinction because of loss of forest land by indiscriminate use by the humans. As a biology student what method would you suggest along with its advantages that can protect such threatened species from getting extinct?

As a biology student, i would suggest ex situ conservation approach for such animals.
It involves placing the threatened animals and plants in special care units for their protection. It .includes offsite collections (Botanical Gardens, Zoological Parks, etc) and gene banks (seedbank, tissue culture, etc).
Advantages of ex situ conservation are:
(i) Offsite collection can be used to restock depleted population, reintroduce species in the wild and restore degraded habitats.
(ii) It is useful in maintaining a large number of genotypes in small area, rapid multiplication of even endangered species, through tissue culture, etc.
