The positive news is that more and more people are now living according to the Buddha's teachings. They avoid killing and eat more vegetable instead of meat and fish. Our global environmental would change better without so many farms with millions of animals to be killed every year. However, rarely can we see the dangerous of our future in our dish every day. Besides, young people tend to try dangerous things like drugs because they have not enough knowledge about them. Parents who live ethically according to the Buddha's teachings would set good examples for their children and help them live healthy and useful lives.
So, the Buddhist way of life now is the only way for us to have a peaceful world. And this can be done only by every of us, not just some of us. Together we can always make things better. The first thing to do to help people understand the Buddha's teachings is to spread the sutras so that everyone can have chances to read them. This is a very difficult task for anyone but it would be easier if everyone knows about it and ready to help.
