The most important thing that we can do is to care. As for something to be sustainable it needs to be looked after.
So we need to care about how our food is produced, how our products are made, how our waste is disposed of and of our impact on the natural world, as otherwise it will soon be unable to sustain us.
I am therefore hoping that 2022 will be the year that enough people care about where we are heading so that we can turn the tide, as the point of no return is fast approaching.
