With lockdown policies in place in most countries due to the Corona pandemic our impact on the environment becomes more apparent each day. With people isolating at home, not travelling, and planes staying on the ground nature seems to recover from pollution: clear canals in Venice, reduced air pollution in China and major cities all over the world, and a fallen global carbon emission. Still, climate change has not stopped, with a record heatwave in Antarctica, which has impacts on all of our planet's climate, and countries like Germany, which are usually blessed with a lot of rain, facing droughts. Realizing how our own actions can positively or negatively affect our environment is a wakeup call for everyone, as we cannot deny the positive impacts of the lockdown on our environment. So, as the official motto of Earth Day 2020 is climate action, we want to discover what technologies may help us in stopping climate change and creating a better future.
