The idea that nature is somehow in harmony and humans upset that balance is inherently untrue. Climate is constantly changing, environments and habitats are constantly changing, and animals have gone extinct for millenia without any human intervention.
Humans are intelligent not because we go against nature, but because we master nature. Human evolution has been a steady progression of increasing mastery over our environment.
We build cities, push back the wilderness, create aqueducts and sewers. We build farms and ranches, breed livestock and grow crops for food and other uses. We convert carbon compounds into usable energy, allowing us to propel ourselves at speeds unfathomed by even the fastest falcon. We have broken our planetary bonds and reached into the vast unknown of space, exploring physically and with the power of observation.
Humans are intelligent because we, and we alone, are capable of observation, introspection and self-control. A lioness on the savanna of Africa may watch a gazelle, but she can't appreciate a sunset. A plant may emit pheromone warnings to its kin, but it can't write poetry. A dolphin may do tricks, but it can't tell you're giving it a dirty look.
If intelligence is the ability to respond and adapt to our environment, then all life is intelligent. If intelligence is the ability to have a discussion on the meaning of intelligence, then we stand alone.
