Light travels at an extremely fast speed. So using "lightyears" means how fast and far light can go in an entire year (a whole lot). So it's a very very large scale of distance considering how fast light travels. Overall, it's mainly used because the distance is so great that measuring in miles or kilometers is not reliable or as sufficient as lightyears
<span>Since it becomes quite difficult to write and interpret this figure using normal units of miles and kilometres, astronomers use light year to interpret it.</span>
Reforestation:- people from Brazil and around the world are making efforts to help protect and maintain the Amazon Rainforest by planting and replacing trees.
