The pollution caused due to the fire work is becoming one of the major problems in both environmental safety and human health. The greenhouse gases released during the burning of crackers causes global warming and eventually increase the temperature of the Earth’s atmosphere. The pollutants from burning the crackers cause health hazard in human being. The particulate matters in the dust such as PM2.5 and PM10 are easily inhaled by the human beings and affect the human health. So a new mixture which has less pollutant, particulate matter as compared with the existing mixture is formed with the help of Boron Carbide as fuel and Potassium Nitrate as the oxidizer. The newly formed mixture is completely Barium free and is much safer to handle than the Barium nitrate. The Boron carbide is implemented in the smoke flare and was found to have the performance as same as the existing composition. So the alternative for the Barium nitrate is proposed and various tests are done for the new mixture.

Green technology is a system that uses innovative methods to create environment friendly products. It is an environmental friendly technology developed and used in such a way that it doesn’t disturb our environment and conserves natural resources. Green technology is developed in such a way that it protects the environment. This research aims to elaborate green technology and related terms along with how it would be helpful in the sustainable development.

The economic rescue packages for dealing with the impact of coronavirus must also be green. The government has to spend large amount of money to sustain jobs and livelihood. This should be done keeping in view green concept. The year 2020 seems to be more remarkable and transformational in recent history. There have been demand and supply shocks across the global economy as a result of emergence of COVID 19. Many European economies faced dislocations as a result of virus spread. COVID 19 is an infectious disease caused by a newly invented coronavirus. They were first discovered in the late 1960s. The study covered the various ways in which coronavirus is bringing changes in the environment. Some of them are positive and the others have a negative impact on the environment. The impact of COVID 19 on International Environmental law was also examined. The environmental consequences of COVID 19 in various countries were also analysed. Italy and China were the countries selected for identifying environmental impact. The various ways in which virus is bringing changes in the environment are air quality improvement, greenhouse gas emission, waste, metro, airline emissions and climate. The interconnections between COVID 19 pandemic and international environmental law at three stages of crisis was made.

The surroundings in which we live comprises of numerous life forms such as birds, fishes, plants and trees. In simple terms, it is the variability and variety of living organisms together with ecological facilities in which they exist. Over the years, the biodiversity has been facing rapid depletion as a result of habitat loss, excessive exploitation of resources, climatic changes, diseases, pollution, poaching of animals etc. In order to correct this scenario, vital steps for biodiversity conservation have to be taken by public in general along with the government and social organizations. Thus, biodiversity conservation has become a major issue in present times. The term biodiversity was coined as a contraction of biological diversity in 1985. Biodiversity may be defined as the variety and variability of living organisms and the ecological complexes in which they exist. In other words, biodiversity is the occurrence of different types of ecosystems, different species of organisms with the whole range of their variants and genes adapted to different climates, environments along with their interactions and processes. Loss of biodiversity occurs when either the habitat essential for the survival of a species is destroyed, or particular species are destroyed. The former is more common as habitat destruction is a fallout of development. The latter reason is encountered when particular species are exploited for economical gain or hunted for sport or food. Extinction of species may also be due to environmental factors like ecological substitutions, biological factors and pathological causes which can be caused by nature or man. Conservation of biodiversity is protection, upliftment and scientific management of biodiversity so as to maintain it at its threshold level and derive sustainable benefits for the present and future generation.
