Humans may have totally over taken the planet earth but that doesn't means that we are the owners of this planet. Being the most intelligent species comes with responsibilities. We have urbanized this planet. n other words we have destroyed the home of many species. Biodiversity is way more important for our survival than we realize. We should let other live if not for them but ourselves.
We did not inherit the Earth from our ancestors; we borrowed it from our children. Everyone is responsible for everything that is taking place on our planet. So keep this in mind before taking any action and you will make this world a little better.
