Covid-19 has impacted the world and it is a reminder for all that nature is supreme when it comes to restoring the balance. We had seen cleaner air and cleaner environment during the lockdown period but if we do not learn from our mistakes and take major steps in addressing those, then we would end up worsening the situation again. Our dependency on fossil fuels, which are rapidly depleting, has cost us a lot in terms of global warming, air pollution and loss of biodiversity and these environmental damages are unsustainable. It is now a high time for us to switch to alternative sources for our energy needs.
