Wind farms and light pollution:
Medium-intensity turbine lights can be brighter than the brightest stars and planets on the night sky up to significant distances. This should be taken into account in environmental impact assessments.

New study confirms that short wavelength light (UV & blue) attracts the most nocturnal insects & that intensity increases attraction for all colours. Longer wavelength & lower intensity outdoor lights should reduce biodiversity impacts resjournals.onlinelibrary.wiley.com/doi/10.1111/... #teammoth 🌍

The importance of place and native names always seems to cause such hateful division in Cymru, which I don’t understand.
It’s so sad people cannot grasp what magic it brings to landscapes to embrace their native Cymraeg names.
Let’s look at ‘The Spinnies’. A local nature reserve 🏴

In a win for polluters, the Trump regime proposed a rule to limit the EPA’s authority to regulate pollution in wetlands and waterways. This would strip federal protections from 55 million acres of wetlands (85% of all wetlands nationwide!), threatening lots of people's drinking water.

Stop warmongers. Also EU ones.
The threats to our security are real and growing.
Europe must urgently boost capacity to protect our skies and our infrastructure.
Poland is the largest defence spender in Europe. And it will be the biggest beneficiary of the SAFE instrument.

Since this meme is trending, let me clarify that it refers to this poem, published in 1880 by Rosalía de Castro (translation by Kathleen March). It tells the story of a woman’s revenge: after pleading for justice in vain, she decides to take matters into her own hands and kill those who wronged her.
