Frozen embryos Main article: Embryo colonization A robotic interstellar mission carrying some number of frozen early stage human embryos is another theoretical possibility. This method of space colonization requires, among other things, the development of an artificial uterus, the prior detection of a habitable terrestrial planet, and advances in the field of fully autonomous mobile robots and educational robots that would replace human parents.[

Yes - almost making it acceptable to keep polluting, not addressing the root causes Another option on the table at the UN must be to successfully invade another planet similar to Earth and claim it for ourselves

It's funny that it's the scientists that are to blame for this mess in the first place - if medical science hadn't increased longevity the effects of the consumer would be so much less The United Nations are tapping all the TEFAL heads to help solve this one - 'A proposal backed by Switzerland and ten other countries would require the UN Environment Programme (UNEP) to prepare a comprehensive assessment of geoengineering, including methods to pull CO2 out of the atmosphere or inject aerosols into the stratosphere to block sunlight. Due by August 2020, the report would examine the underlying science and technology, and how to govern research and wide-scale use.' https://www.nature.com/articles/d41586-019-00717-6

So youve been trucking 15 years own your own rig and can only pay yourself 250 a week? With a family too - you must be kept from starvation by tax credits. Anyone can cut lawns, almost anyone can cut most hedges. If youre in all the local papers and magazines and cant make more than 250 on grounds maintenance you need a PAYE job working for someone else. Hedges arent as seasonal as mowing. With trees unless its ground felling or small bits off a ladder, it will be a long road. But tree climbing is the most excitement Ive had working in gardens. Its not just buying vehicles, machinery and doing courses, the best workers have bothered to read a bit about trees and plants in general. If you only want to be a climbing chainsaw operative then dont bother to learn about trees, just learn how to safely get rid of them.

my local council have a plan for 10,000 new homes over the next 15 years - I wrote to them asking if they had seen Constable's painting The Haywain. What we are doing to the environment now is just covering it with a concrete cancer. Politicians always put economic growth before environmental sustainability. It wouldn't matter if the government made it compulsory for every 17 year old to drive a government issued supercharged V8 if there were half the number of people. It's only going to get worse. We are so lucky to be alive now, another 300 years time the countryside will be photos in some history book. So now China is scrapping its family planning laws so enough new worker units are produced to pay income tax for the current billion odd to live off when they retire.. There are no answers that don't involve castration and walking to the supermarket scum is too nice a word for the politicians that think the answer is more houses, not less people

when the same (or similar) bug/fungi complex took out some English oaks a few years ago in California, looks like DEFRA were concerned enough to go into it in some detail establishing known host plants and possible methods of entry into UK- although our climate is vastly different, they seemed to think there was some risk from imported planting material The table of confirmed reproductive hosts in the document below is huge - so how this relates to the pattern in the Johannesburg photo I won't make any more silly guesses https://secure.fera.defra.gov.uk/phiw/riskRegister/downloadExternalPra.cfm?id=4055

Carefully scaling from the photos using the most advanced CAD mathematics that tree is between 130ft and 130ft 2 inches

argument against single species avenues: 'An invasive beetle from Asia that has infested trees lining the streets of Johannesburg’s most exclusive suburbs is sweeping across South Africa, and scientists are powerless to stop it. The only defence is to cut down and burn infected trees in the city, one of the largest urban forests in the world. It is estimated that half a million of Johannesburg’s ten million trees will be invaded by the polyphagous shot hole borer, which is also wreaking havoc in eight of the country’s nine provinces. It could soon cross borders to blight forests elsewhere in Africa.' Times Uk

right that's it Haynes manual will be dusted off and my transit diff is getting an oil change, never even checked the level in 70,000 miles of ownership, total covered 145k. Its done well really. Edit - a bit of poking around on the transit forum re diff (Mk 6) 'Transit rear axles were designed as filled for life. ' Also says in the Haynes manual that checking diff oil not a Ford service requirement. No drain plug - will check the level anyway and just squirt some in if needs be. Maybe go fishing for swarf with a magnet

'yes we do and we're making a killing just marking it up??' all kinds of contraptions on alibaba

it does look promising - turns out you can get smaller ones, they are called carbide cluster blades from other manufacturers, maybe this 115mm one on a grinder would be useless, surely you need one on a nine inch grinder if its a thick root? https://www.ebay.co.uk/itm/Spectrum-KRB115-22-ULTIMATE-Karbite-115mm-Carbide-Cluster-Multi-Purpose-Blade/123645582913?epid=23012079162&hash=item1cc9d9de41:g:fe4AAOSw6Vhbn6F9:rk:6:pf:0

thinking about it I see your point - even that chainsaw grinder wouldn't fit down a post hole that deep, a six inch root at 18" below must surely mean some fencers opt for a bodge and chance setting the post a bit shallow on that one.

But they dont have very long bars, and would they blunt on flint etc? If you poked it down a post hole to sever a root?

That is the thing though those grinders that run off a chainsaw have an advantage over 4 stroke in that the 2 stroke will be lubricated working at any angle, so could be used vertically if the hole is wide enough, theyre quite long machines. Whats the idea with the concrete chainsaw? Thought they were for cutting openings?

Its a good thing there are some woodland tpos in uk, or more big trees would be lost, a few plants and animals move in from surrounding areas increasing biodiversity, but you cant expand the habitat of mature native broadleafs that are a century or more in the making

When youve found the need to spend another three grand one of those predator 661 chainsaw stump grinders you could poke about on the roots

I also saw the Makita is most powerful out of those ones, if its quicker it may be less wear on your shoulders, or more? Perhaps it has class leading anti vibes

I appreciate you can fell 70 percent big native trees in an area, leave a few scattered about and smaller oranisms colonise the previously shaded understory, what gets me about mankind is every square meter of woodland is seen as a resource. Theres no scope for owning something without needing to 'improve' or make use of. At least it wont be another housing estate just yet.

so if biodiversity is a numbers game you could hit the jackpot by making it so lots of different small organisms flourish instead of a few big ones. Kew gardens must have high biodiversity, compared to the woodland it must have been before man arrived

Have to agree with this - there is something to be said for looking at woodland not in terms of 'management' , but as nature. A properly managed woodland should look like one did before man evolved. Of course, man has evolved, so it's only natural you'll want to steal a few trees for heating or building

if people become aware that topping is universally bad is there another term that I could use to sell my service? Lopping? Trimming? Surely a holm oak or sycamore wouldn't have rotted as bad if brutally topped by a non arb approved 'practitioner' like myself?

Can be retopped safely from a helium balloon, probably much cheaper than a mewp

Seems theres good money in it in China - some are using a helium balloon to get up there. New ticket on the way - chainsaw from a heium balloon http://www.sixthtone.com/news/1001195/the-life-and-death-of-a-pine-nut-picker

they aren't as big as that one, and a did have a plan using something what Johnny Walker on here used to call a floating rope, basically you could have something round the trunk at various heights below the top anchor so if the top comes away you take a fall, but only as far as the next sound anchor. A bit like the rigging fishing pole technique. You're right I do need to get back up there while its still a silky job, was kind of hoping they'd have moved house

you do have a good point there - that is a fair size one and even if its halved it would be a dangerous job to retop in 5 years time without a mewp. I like the ladder height option - the mature trunk is a garden feature the owners may want to keep
