All animals and plants have to change or adapt all the time to survive. These changes are very slow, but can be seen by looking at the fossil record. During the cold times in Gondwana (around 270 million years ago), only animals and plants that were able to survive in cold environments were able to survive there, but once the continent warmed up other animals were able to live there, and cold-adapted animals either had to find mountain tops to live on (where it stayed cold), or adapt to the new warm environments.
As plants were unable to migrate, they changed or died.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
