Taking your partner on a regular date will not directly save the planet but it will definitely turn disgruntled Mary into happy Mary, which means Mary is more likely to do something good elsewhere.

No-one feels like saving a whale, care whether Bella the cow is being treated fairly on a organic farm or feel like hugging a tree if they haven’t been hugged in a while themselves. If your own life is dull, and lacking in fervour, you need to pull yourself towards yourself and arrange for a regular date night.

A happy home life will have positive spin-offs. Forget about clean water, pollution and recycling for a moment – our biggest asset is Time and we are waste way too much of it. Commit to spending more time with your loved ones and see the positive waves ripple out into all the areas of your life.

But what minutes! Count them by sensation, and not by calendars, and each moment is a day.
- Benjamin Disraeli

A true man does not need to romance a different girl every night, a true man romances the same girl for the rest of her life.
