As promised, a more difficult nut for today!

I will give this one 3/5 difficulty.

Hint:

Answer and some fun facts about this nut:

Tune in tomorrow for more nutty knowledge!

Despite their drab color, I find these quite beautiful!

I expect this one will be fairly easy, so the next one I post will be a bit harder.

Need a hint?

Welcome to the challenge for November 9th which is the 3rd one so far after #8 and this post with the original idea.

Warning: Comments may contain spoilers, so only read them once you're ready.

Inspired by this post by @fossilesque@mander.xyz, @LibertyLizard@slrpnk.net proposed to turn that neat idea into a challenge series. It's not my idea, so feel free to post your own challenges here or in whatever community you find appropriate.

Now back to the game - let's see who'll be the fastest nutter of the day! ;)

Warning: The challenge has been solved already, so don't check the comments if you want to avoid spoilers.

Counteract the Bleakness of the Modern Urban Environment of rampant homelessness and over-priced housing by propagating and planting trees in neglected urban spaces. Tony Santoro shows you how with help from the Department of Unauthorized Forestry.

New research shows that, instead of replanting rainforests, allowing them to bounce back naturally would store loads of carbon and water.

The global push for biomass that can be burned for energy is causing concern about the price Indonesia's forests are paying.

Australia just overturned 20 years of case law to allow environmental groups to take corporations harming the environment to court.

Please crosspost to other communities which might be fitting.

Harvesting in Bulga state forest, inland from Port Macquarie, is just 400km from global nature-positive summit the government is hosting

• The EU parliament and council is considering a 12-month delay to its deforestation-free products regulation, which will require exporters to prove that beef, soy, rubber and other harmful commodities aren’t sourced to deforested land.

• The law was supposed to go into effect January 1, 2025, but faced mounting pressure from exporting countries and the industrial agricultural sector.

For the Maasai, Nyekweri forest has such a high ecological and socio-cultural value. But new conservancies aren’t working as best they could.

A really innovative study that went beyond statistical association and actually planted trees in low-tree neighborhoods and measured the impacts.

After the plantings, the research team reassessed residents' health. They found that those living in the greened area had 13-20% lower levels of a biomarker of general inflammation, a measure called high-sensitivity C-reactive protein (hsCRP) than those living in the areas that did not receive any new trees or shrubs. Higher levels of hsCRP are strongly associated with a risk of cardiovascular disease and are an even stronger indicator of heart attack than cholesterol levels. Higher CRP levels also indicate a higher risk of diabetes and certain cancers.

A reduction of hsCRP by this percentage corresponds to nearly 10-15% reduction in the risk of heart attacks, cancer or dying from any disease.

Although several previous studies have found an association between living in areas of high surrounding greenness and health, this is the first study to show that a deliberate increase in greenness in the neighborhood can improve health.

Nearly 40% of the Amazon's vital climate regions are unprotected, raising concerns about deforestation and the urgent need for preservation.
