It's very good that compost material added to agricultural soil can reduce greenhouse gases, particularly good that it would "constitute about 8.6% of the total EU emission-reduction objective."

@AnonySchmoose it's something we can all do

Since I planted, the greater number of birds have deposited seeds which grew into tree seedlings and other plants. Most of the seeds birds brought were Koa Tree, African Tulip Tree or Quince Tree.

I have many Arica palms so close together they're uncountable. There are fourteen countable trees, tall bamboo, tall shrubs, a few vines, heliconia, ginger, vanda orchids, and cultivated flowers and wildflowers. It's a very thick garden.

I hate to tell you residental grass is a absolutely poor way of sequestered of Carbon.

The use of chemical fertilizers and pesticides actually kill the very bacterial organisms they help to sequester the carbon and nitrogen to bind into the soil the grass is planted on!

The trees and tall things I planted cut down on noise ... except for the wild singing of birds, which entertains. I suppose what I have now is a woodland. The animals love it, we love to sit outdoors, the neighbors appear to love it.

@AnonySchmoose For many, many years now, every dead and fallen tree that I harvest for firewood I plant at least 2 in replacement, hence, in the area from which I source firewood there are now more trees of various ages growing than there were before and the property owner, a Sheep Grazier, is far greater pleased than ever since his stock now have greater areas of shade in which to shelter from the summer heat, more ground feed growing under the trees and, of course, the native birds and animals have returned, en- masse and repopulated the area as well. Sadly though, the drought we are enduring out here has taken quite a toll at present, but once the rains return then my tree planting will continue on in earnest again.

@Triphid
I read or heard that if you create a small forest (tree density), other plants will be better able to survive drought. Trees give shade and drop leaves which sequesters water. More plants grow, more animals fertilize the area, etc.

@AnonySchmoose Sadly, that doesn't work with most of the Eucalypt varieties out here in Australia since many of them exude a hormone into the soil to prevent/deter other trees/plants encroaching into their root space but it can be overcome by using native plants that have evolved a tolerance to that hormone which is what I do.
But, they animals do also fertilize the ground as the rest/gather under them and given the great depths that Eucalypts send their roots down they too create what are known locally as 'Water Soaks' sometimes as deep down as 100 metres and often containing water sources with as much as hundreds or thousands of litres in them.
But, yes you are right, the greater the number of trees in an area the greater the number of seedlings, etc, will grow and survive drought conditions so I often grow seedlings at home such as native Acacias, they can fight against the Eucalypt hormones and grow under Eucalypts, give shade and shelter as well as a source of food for the animals, etc.
Once, about 100 years ago, this region was almost completely devoid of trees because the Mines here cut them down for both timber props for the underground mining works and fuel for the Smelters ( no longer in use here btw), we had dust-storms that literally blanketed the town and sandhills that literally buried houses on the outskirts, now we have worked for decades to re-generate the native vegetation, the dust-storms are far less than before, except in these drought times, the native birds are re-populating, most m homes and streets have trees of all kinds growing in and around them, the town is green now where once it was a dry and barren place.
Hopefully the drought ends very soon, the countryside will recover and more and more trees will grow.

@Triphid
Yes ... native plants have built-in resistance to many problems plants encounter, including drought and pests. Glad to hear you're greening the countryside and town.

@AnonySchmoose Well the town has done the greening by itself, I'm just doing my bit on my friend's Grazing Property as a thank you for the firewood and because I want to see his land and business prosper and the environment return to how it was BEFORE the Mining Companies, B.H.P in particular, raped it for their own financial gains.
Btw, B.H. P. = Broken Hill Proprietary Limited, started here in Broken Hill as the first Mining Company here when Silver, Lead and Zinc were discovered, they literally worked their employees as slaves, made their millions, then left the town for dead but it didn't die as they had hoped.
Ask any old miner here and he will tell that B.H.P. was a PARASITE of the first order, they are hated and reviled by the older generations, me included.

No, I think that Humans need to start thinking more about the Natural World and less about themselves after all it IS we who are killing this planet and almost everything living on it.

@Triphid Honestly? Homosapian Sapiens should be extinct. Natures biggest mistake.
