Humans, through greed, ego and hubris, and their desire for more of everything, have taken so much away from the world and put almost nothing back. Almost a thousand species of animals are extinct because of humans since the year 1500. Humans keep taking more though, and pour waste into waterways and oceans, pump toxicity into the air and covered much of the planet's surface with concrete. Humans have brought wars that have destroyed nature, (nuclear weapons), and deforestation devastates ecosystems.
Humans are the true garbage on this planet, and have not made it better. They haven't even made it better for themselves...Toxic waste, acid rain, melting polar caps, famine, disease, viruses...Yep, humans are the garbage. I feel ashamed to be one to be honest; every human should.
