Nature can provide almost everything human beings need if we follow her rules.But if we break the rules,she is likely to be cruel and lash out at us.
  The outbreak of the COVID-19 in China and some other countries is an example.Dr Peter Daszak,president of the US-based health organization,said,"This outbreak is a lesson for us.On a global scale（规模），human population density（密度），wildlife diversity,and land usechange are what drive new pandemics（流行病）．"
  In ancient times,people needed to rely on nature to survive so they held it in awe（敬畏）．For example,the American Indians believed that humans are a part of nature and nature is apart of humans.Chinese ancients always tried to keep the harmony between nature and human beings.
  However,as human beings master more knowledge and make more advanced tools,people try to change and even conquer nature.They use more land to make buildings and capture wild and rare animals to suit their own needs.In this process,humans gradually lose contact with nature and even throw it out of balance.
  Although we don't know for sure what first caused the COVID-19 outbreak,it's time for people to reflect on our relationship with our planet and reconnect with this world and everything that we've been given.After all,nature is not the place to visit.It's our home.
