We will have to change how we live. Some changes will be relatively easy while other changes will affect finances, the economy, and jobs.

However, there is something that is quite easy to do and costs relatively little.

That 'something' is planting and caring for trees.

The good news is that this isn't controversial because most of us have enjoyed trees ever since we climbed them as kids or held picnics in their shade, to mention only some reasons.

Planting and caring for trees is good for human beings, and good for the environment.

Trees are the world's single largest source of breathable oxygen; they offset carbon emissions; make our agricultural areas and gardens more sustainable; prevent salinity and soil erosion; and sustain native animals. This is an incomplete list!

Of course, trees also have many commercial uses.

In our warming, drying climate conditions, trees provide cooling shade and return moisture to the atmosphere.

Here is a big question: at a time when forests are burning and huge areas of bush and forest are being uprooted, can we just be spectators, or should we, as collective humanity, act? If so, how?

A famous American president, Theodore Roosevelt, said, 'To exist as a nation, to prosper as a state, to live as a people, we must have trees.'

Trees are good news for people, climate, and the planet!
