Nature is not a Singular Thing, but an aggregate of Many Things.
The Sun projects light, heat, and other forms of radiation. Her Light can provide vitamin D, which is good for our bones. Her Light also provides the ingredients for plants to make food.
But that Light can also cause burns, illness, and skin cancer in the case of prolonged exposure, especially to people such as myself who are very light-skinned, and She does not change her Light to accommodate us.
The Sun brings Life and Death together in the same Light, and our presence has had absolutely no effect on Her projection. If She's aware of us(if She's even aware at all), She doesn't care.
Even when the Rain comes, the Sun continues to shine. Her Light just doesn't reach the cloudy place. (Fun side note: that's a large part of why Northern Europeans have light skin; those regions have a lot more rain, clouds, and fog than other parts of the world, in addition to having long winter nights. So we evolved skin that was better capable of absorbing that Light in those low-light lands.)
Ethics are about promoting life while avoiding death as much as possible. In Nature, both Life and Death come together from the same thing. When the Sky and the Earth make love, the resulting Rains bring both Life (in the form of fertilizing and feeding plants) and Death (in the form of floods). Their passion can often be so great as to produce great winds, bringing Death to vast areas of land, but that also spreads the Life-bringing Rain to larger tracks of land.
