Canadian singer-songwriter, Neil Young, has always been an outspoken advocate for environmental issues and has many songs that bring up the problem of our suffering planet. One of the most gorgeous and heart-wrenching is his appropriately named song “Mother Earth” which acts as an open love letter rife with regret to Mother Earth:
