人类活动总的来说使熵值的上升加快还是减慢

我的推论(因为不知是否正确,求高人指点):
假设没有人类(甚至没有生物),地球从太阳处接受的能量会怎样?应当是由温度高处直接传递到温度低处,然后耗散,最后完全成为"无用能量".
而有了生物及人类,阳光被漫长的过程转化为化石燃料、电能等能源形式,虽然这个过程也造成了熵的增加,但就像高处掉落的石头不是直接落地,而是被中途接住了,虽然终归还是会落地,但是过程减缓了。
这个结论如果正确的话,就与现在流行的“人类制造了过多的熵”这个论调矛盾。
本人不是学物理的,纯粹个人好奇,求挑漏洞,指正错误。
对不起我英文很烂的,一楼的大姐麻烦翻译一下啊
刚发现贴错区了,麻烦大家当物理题答吧……
jinzuojinyou88 麻烦解释一下吧^
答案满意再追加40分

实际上是加快的。
我这学期学过一门课的名字叫statistical in thermodynamics.
一下用英文解释,
you know that 熵 is called entropy in english, acctually in thermodynamics, there is a canonical saying that things happen spontaneously causes increasing in entropy, so it seems to be opposite to my opinion, because it seems that all things will happen spontaneously without people, however almost no pure spontaneous or non-spontaneous change exsists in the world, that is to say some spontaneous change are caused by some non-spontaneous change, therefore from my point of view, people use energy, do some non-spontaneous things but cause more spontaneous changes, 所以,熵还是在被人类加速。

减慢.
