“Every nation has a moral obligation to safeguard the future.”

In digital era, privacy must be a priority. Is it just me, or is secret blanket surveillance obscenely outrageous?

The debate’s over. The people who dispute the international consensus on global warming are in the same category now with the people who think the moon landing was staged on a movie lot in Arizona.

We’re operating this planet like a business in liquidation.

Each and every one of us can make changes in the way we live our lives and become part of the solution [to climate change]

When fear displaces reason, the result is often irrational hatred and division.

No matter what looms ahead, if you can eat today, enjoy the sunlight today, mix good cheer with friends today, enjoy it and bless God for it. Do not look back on happiness — or dream of it in the future. You are only sure of today; do not let yourself be cheated out of it.

The future comes slowly, the present flies and the past stands still forever.

It is brave to believe in tomorrow.
