Again, it's all a matter of perspective. Some may look at the world and see only the suffering and brutality. An entire world where life is valiantly struggling to survive, but inevitably suffers and dies. And yet through all of this injustice and suffering, life perseveres. In such a world some may choose to see the suffering, but the stoic in me chooses to see the beauty instead.
Most people don't see it that way.
Humanity, in general, isn't content to just let nature have its way.
Most of humanity favors making life more comfortable and certain, and, to some extent, structured. Most people understand that we can work together to enhance life for all of us.
I would imagine that you are not really so content with nature either. You, obviosly, have a computer and internet service. You, likely, have a phone, a television, take medications from time to time, and enjoy non-natural heat in the wintertime, and perhaps cooling in the summertime. I imagine that you drive a car, keep your grass mowed, and have artificial lighting in your home.
Humanity has eschewed the practice of imposing slavery on others, at least in the vast majority. Humanity has embraced the notion of human right. In the US, the right to life, liberty, and the pursuit of happiness is enshrined in the Constitution.
