It is mandatory to expand tree plantation in industrial area to minimize the threat of pollutants. For green belt development, it is necessary to use plants that are tolerant to air pollution. The present study includes Air pollution tolerance index (APTI) of selected plant species with the help of biochemical analysis. On the basis of APTI and some other socioeconomic and biological parameters of plants, Anticipated Performance Index (API) was calculated. Out of twelve species, Ficus benghalensis showed to be the most efficient among others. As per classification of API, Ficus religiosa tree species is classified into the moderate category. Based on the APTI and API, appropriate plant species for green belt development in industrial area were identified and recommended for mitigating the pollution. 展开更多

Having traveled through four gates of the palace,Śākyamuni became aśramaṇa to seek the solution for mankind’s“birth,aging,sickness,and death”.Finally,he found the truth-the ineffable reality of the world.To expound the truth to people,he had to use the linguistic convention to express the inexpressible state.The primary purpose of this paper is to use the Buddhist perspective on language based on the Prajñāpāramitā-sūtras,to compare the daily language in the world-especially linguistics and philosophy of language in academia;hence point out their limitations,defect,or pitfalls,to see the crux of the language problem,and turn to the path of Buddhist practicing as well as“bringing wisdom from knowledge”.I will elaborate on six points in full text:I.Introduction,including the five key concepts.II.The comparison of the Buddhist perspective on language with linguistics and philosophy of language.III.The perspective of the language in the 4th,7th&16th assemblies.IV.To understand the reality of the world,we have to cultivate the“hearing,contemplating,and practicing”based on Buddha’s words.V.The significance of the Buddhist perspective on language in this era.VI.Conclusion. 展开更多
