No Human?

What invention would the world be better off without, and why? (Kalamazoo)

I strongly believe that the world would be better off without human, invented by God (according to Christianity). Every day, we see that we, human, are doing more harm than good to the environment, the world. We raise the temperature of the earth, trap the heat inside the earth, releasing a lot of harmful gases, create greenhouse effect, and heat up the earth, creating global warming. We are not only destroying the environment, we also destroy lives and even ourselves. We create many weapons to protect ourselves from ourselves and also to bring down ourselves, harming the environment even more. It clearly shows that we are extremely selfish. Everything that we do is, mostly, based on our interest. We do not do any good to anyone, except ourselves. Many leaders are corrupted, allowing harmful things to happen to get the most benefit out of their position. The earth probably has a cycle, extreme changes in climate; human, however, speeds up such cycle and going to bring about the phrase change earlier than usual. Human destroy the regulation of nature. We also builds in floodplains, knowing that it will be harsh once water comes, but, still allow it to happen because the flood is affecting “those people”, not “me”.
