Human beings are considered as the most developed species on the planet. Though all the species, zoological or botanical along with environment constitutes ecological system. The sustainable development depends on the right balance between all which invisible in this era of technological advancement and population explosion. On one side deforestation and on the other mining and industrialisation may be blamed for the same. More population needs more dwelling and more agriculture production, failure of the same results consumption of animals which creates conflicts between humans and animals, the one which is one of the main consequences of deforestation too. Consequently, the wild animals have little option but to infiltrate 'human settlements' in quest of food and to migrate since people are robbing them of more and more of their natural environment. This has led to an increase in fatalities, including those of humans as well as animals. Shifting agriculture, rotational felling, other biotic pressures, diverting forest areas for development purposes, etc. are the primary causes cited for the decline in forest cover. The country's microclimate, hydrological cycle, soil quality, biodiversity, etc. have all been harmed by on-going illegal tree cutting, making it more susceptible to any untoward incident. The country, India, offers a diverse ecosystem that includes magnificent tigers, elephants, and birds after thousands of the years of evolution. Unfortunately, deforestation, a problem that is only becoming worse, poses a threat to this irreplaceable natural resource. Wild animals require proper habitat or places where they may live in peace and comfort. These are the places they go to relax, sleep, eat, procreate, hide, and flee from predators. Animals lose access to vital supplies and are exposed to new dangers, which have not only resulted in tremendous impact on entire ecological system. Moreover, India has a significant chance to build a legacy of achievement in the face of such pressing issues during its G20 Presidency. Therefore, the paper will be an attempt to thoroughly analyse the problem of deforestation and its social, environmental and legal impact in light of Sustainable Development Goals and India’s G20 objectives and also portray probable solutions in form of the suggestions.
