If we don’t stop cutting down trees for agriculture and to build houses then the future generations will not think about trees when they hear the word Earth.

I hope, as your father, I’ve done enough to instill within you how science is a wonderful adventure.

There is a promise in the Bible: ‘I shall restore the years that the locusts have eaten’ and that points to a promise of complete healing and restoration. But until that comes I intend to do my best to ‘save the planet’ in whatever way I can, and I encourage you to do the same.

My desire is for clean air, clean water, rich soil, and healthy nutritious food for you and all children always everywhere.

I promise that I will change my behavior to benefit our trees.

The blue sky will no longer be grey, and the bleak clouds will be vibrant.

If there is one thing that I taught you it is to be honest in your decisions as they pertain to yourselves and the earth in which you live.

I can feel the change happening — many people are working to transform the world.

Sometimes I think we will never make it, but I know we must keep trying.
