Trump officials set to approve β€˜forever chemical’ as pesticide ingredient Critics say that fifth Pfas Trump’s EPA has proposed for approval this year would put food and water supply at risk

During his campaign, Trump (& RFK) promised to rein in the use of dangerous pesticides, but the EPA has loosened oversight and is accelerating pesticide approvals.

Notably, the top 4 positions in the new Trump EPA’s chemical safety office are held by former pesticide and chemical industry lobbyists

But the sketch I have here attempted to give of its varied functions shows us that it is really a most complex structure, a wonderful piece of machinery, as[ 259] it were, which in its various component gases, its actions and reactions upon the water and the land, its production of electrical discharges, and its furnishing the elements from which the whole fabric of organic life is composed and perpetually renewed, may be truly considered to be the very source and foundation of life itself. This is seen, not only in the fact of our absolute dependence upon it every minute of our lives, but in the terrible effects produced by even a slight degree of impurity in this vital element. Yet it is among those nations that claim to be the most civilised, those that profess to be guided by a knowledge of the laws of nature, those that most glory in the advance of science, that we find the greatest apathy, the greatest recklessness, in continually rendering impure this all-important necessary of life, to such a degree that the health of the larger portion of their populations is injured and their vitality lowered, by conditions which compel them to breathe more or less foul and impure air for the greater part of their lives. The huge and ever-increasing cities, the vast manufacturing towns belching forth smoke and poisonous gases, with the crowded dwellings, where millions are forced to live under the most terrible insanitary conditions, are the witnesses to this criminal apathy, this incredible recklessness and inhumanity.

Wow. I did not know that Alfred Russell Wallace (co-discoverer of evolution by natural selection) wrote a book in 1904 about the biological potential for life on other planets, and I've just found this extraordinary paragraph setting out the insanity of atmospheric pollution [1/3]. In 1904!
