====== Green wave ======
 <font 11pt/inherit;;#000000;;inherit>wave-like temporal variation of vegetation consumable by animals, e.g., young grass. Such variations occur both on annual and longer time scales (due to climate shift) and have spatial patterns. Use grassland as example.</font>
 <font 11pt/inherit;;#000000;;inherit>Grassland is a land use type defined in ecology and climate research.</font>
 <font 11pt/inherit;;#000000;;inherit>The growth of grass has variations on annual scale, and the</font>
 <font 11pt/inherit;;#000000;;inherit>distribution of grassland</font>
 <font 11pt/inherit;;#000000;;inherit>changes with climate. For example,</font>
 <font 11pt/inherit;;#000000;;inherit>Mongolian</font>
 <font 11pt/inherit;;#000000;;inherit>grassland did not exist during the Last Glacial Maximum,</font>
 <font 11pt/inherit;;#000000;;inherit>while</font>
