Be who you wish, nature is around you no matter what you do, always remember that each mistake you did, it will punish you. It is not a rule to be a conservationist but the nature will oblige you to be. Biology and other environmental courses should not be undermined or underestimated but they should be learnt accordingly and more practiced. I encourage young people to invest their energy in sciences and don't mind about anything. Science is life. Living this life will make you a strong man and whom the society wish to live with.
