Would you say it's a frightening or an exciting world we live in ?

I think both. The natural world is so beautiful, and so amazing. I will never cease to appreciate the wonder of a lovely sunrise, the sound of birdsong, and the perfume of flowers. There is always something new to discover and experience.
What's frightening is the things the people in the world do. They are so cruel to the earth and each other. They create hate, violence, and war with others, instead of loving one another, and caring for the earth, as we were meant to.
