It is true that humans are responsible for a lot of terrible things in the world, however, it is also true that there is a lot of good that humans do. To ignore this is to ignore the fact that humans are complex creatures capable of immense acts of love and kindness. For instance, the manatee video that you mentioned is far from the only example of humans engaging in compassionate behavior. Every day, people are rescuing animals, providing them with food and medical care, and creating organizations and campaigns to protect them.
Furthermore, the fact that so many people reacted positively to the video is evidence that we are capable of recognizing and celebrating the good that we do. This does not mean that our faith in humanity is misplaced. Rather, it shows that we are aware of the harm we can cause, and that we are striving to be better. Even if the video was staged, it still serves as a reminder that some people are making an effort to do good in the world.
In conclusion, it is true that humans are responsible for a lot of terrible things. However, this does not mean that we should ignore the good that we do. Instead, we should acknowledge and celebrate it, so that we can continue to strive to be better. Our faith in humanity is not misplaced.
