The zebra must eat plants to survive. So with no plants, the zebra would go extinct or become endangered. The plants need sunlight, water and soil (for the roots) for the plant to be healthy and contain lots of nutrient the zebra needs.
Also, without plants, the zebra cannot have any unsaturated fat, which we all need. Finally, the plant also contains water. So if the zebra is in need of water, the zebra can just have that, even though it might not give much water as a river or a stream would.
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.
