You have to know yourself, and that once you know yourself, then you cannot be bound by - because sometimes we are bound by other people's thoughts, because we are not sure about ourselves. But once you know yourself... I guess it is really an expression of the biblical statements that the truth will make you free! When you know, then you are free, your mind is free.

Anybody can dig a hole and plant a tree. But make sure it survives. You have to nurture it, you have to water it, you have to keep at it until it becomes rooted so it can take care or itself. There are so many enemies of trees.

What is really important is to educate people how to protect themselves and how to ensure that, despite their poverty, they can get tested and access drugs. So I just hope that those who can will make those drugs available.

We tend to put the environment last because we think the first thing we have to do is eliminate poverty. But you can't reduce poverty in a vacuum. You are doing it in an environment.

When these resources are degraded or polluted, then there are fewer of them for the rest of us, and then we start competing for them and eventually as we compete, there are those of us, who have the capacity, who have the ability to be the controllers, to decide who accesses them, how much they access, and eventually there is a conflict. Those who feel marginalized, those who feel excluded, eventually react in an effort to get their own justice, and we have conflict.

We are called to assist the Earth to heal her wounds and in the process heal our own - indeed, to embrace the whole creation in all its diversity, beauty and wonder. This will happen if we see the need to revive our sense of belonging to a larger family of life, with which we have shared our evolutionary process.

Unfortunately, the issues of climate change, unlike many other issues, are very subtle because the changes we observe are very, very subtle.
