What we can not afford to lose
What had been separating us from animals?Why could we humans dominate the world and all other animals can’t?Of course,most people would answer that because we humans have better brains than animals.Well,yes but only after millions of years of evolving.At the very beginning,human brains were no better than any other animals.The difference was made later on when humans could learn better than all the other animals.So it was just one thing
that had made all the differences between humans and animals,which is education!
Education is the most important part of human civilization,which was what had made us today,without education the world would not have changed at all.It might be standing still as millions of years ago.When we did not learn how to use fire,then we probably are still eating raw meat and drinking animal blood!If we haven't learned how to make clothes then all of us would be still be looking like Adam and Eve,bud naked!If we haven't learned how to build houses then we would be still living in caves.
If we haven't learned to invent writings and words,then all of us would still have no names but everyone is called Ar Er or Le La's.There would be no cars,no ships,no trains,no airplanes and certainly no rockets!No movies to go to,no TV to watch,no restaurants to enjoy ourselves but have to catch our own food with a flint tip spears.The best luxury feast would be
catching of a woolly mammoth.Apart from it could feed the entire population of the cave,also a large warm hairy fur quilt can be made from its skin!
The worst thing is we would not have money!AND NO COMPUTERS!We may not know what other people living in the next cave to ours were talking about,because they speak another
language!We shall have no factories to offer us jobs and no shopping centres for us to buy things.Surely ladies wouldn’t be as beautiful as they are now without any of the beauty products!
Now,you see why learning is important to you?They are not just for yourself but for the entire
civilization.Through learning,everyone will contribute a small part of what have been learnt to improve our living in the long run,which we can't do without!So,no matter what,education should be put in the first place of every one of us,more education and learning the more advancement for our precious living world.
Therefore,before you start to dream about your dreams,you should first consider whether you have the abilities to achieve them.No matter how bad you want your dreams to come true,you must have something,some skills,some knowledge to back you up and help you along.Needless to say all these only would come from education.In other words,education is what we can not afford to lose!So,happy learning everyone!
