The ‘World Environment Day’ is being observed today globally to spread worldwide awareness on environmental issues. The Day is celebrated every year on 5th June since 1974. Almost over 150 countries participate each year in the event to take action on significant environmental challenges the planet faces. The theme for this year’s World Environment Day is ‘biodiversity’, a call for action to synergize global efforts to combat the species loss and degradation of the natural world. Human actions, including deforestation, encroachment on wildlife habitats, intensified agriculture, and acceleration of climate change, have pushed nature beyond its limit. It would take 1.6 Earths to meet the demands that humans make of nature each year. If we continue on this path, biodiversity loss will have severe implications for humanity, including the collapse of food and health systems. The emergence of COVID-19 has underscored the fact that, when we destroy biodiversity, we destroy the system that supports human life. Today, it is estimated that, globally, about one billion cases of illness and millions of deaths occur every year from diseases caused by coronaviruses; and about 75 per cent of all emerging infectious diseases in humans are zoonotic, meaning that they are transmitted to people by animals. On World Environment Day today, let us take a firm pledge to protect nature & environment by saving energy, water, reducing use of disposable plastics, promoting reusable materials, planting saplings & reducing dependence on fossil fuels by adopting renewable sources of energy.
