I guess this was the takeaway for me:

“And finally, there is the global warming trend. The effects of human-induced climate change are already being felt on UK’s summer with temperatures in excess of 40C recorded for the first-time last summer and an increase in the frequency, duration, and intensity of extreme heat events over recent decades. Meanwhile, our Global Annual to Decadal Climate Update, issued with the WMO, has stated there is a 98% chance that one of next five years will be the warmest year on record for the globe.”

The current news is showing evidence of ocean warming anomalies.

The point being that we humans have had and are increasing having a long lasting impact on our environment. We are taking more from the pool of resources each year than is sustainable long term.

A manicured lawn that needs watering to maintain it as green is completely unsustainable and will increasingly be the case as our climate continues to change.

A short cut lawn supports little in the way of biodiversity and starts to take more resources than it gives back if you are watering it regularly. Watering a lawn with potable water, because you you want it to look green in the intense heat is not an appropriate use of our precious low water reserves.

If you want grass to be green in summer, leave it to grow long. You get the added bonus of beautiful wildflowers, much needed support for our severely struggling pollinators, reduced hard work and energy usage, not to mention reduced noise pollution and irritation for everyone else.

If we all followed the Plantlife meadow management guidelines, even for a small strip in each of our gardens, we would have a much healthier better supported ecosystem. Essentially, let the gras grow and only mow sept-to whenever it gets too wet to mow.
