DDT use declining toward oblivion: UNEP caption – Source: DDT Expert Group. Report of the Effectiveness Evaluation on DDT Pursuant to the Article 16 of the Stockholm Convention Animation prepared by: UN Environment Chemicals and Health Branch 2016, with the latest information available and may not reflect the current status.
More than 180 nations signed the Persistent Organic Pollutants Treaty (POPs), often called the Stockholm Convention. The treaty pledges nations to voluntarily work to rid the planet of dangerous and toxic organic chemicals.
DDT is named in negotiation documents as one of the Dirty Dozen most toxic pollutants; however, because there was no alternative that performed exactly like DDT, the nations made a special addendum to the treaty to allow any nation to use DDT to fight disease vectors (insects that carry disease). The World Health Organization tracks use of DDT.
In 2001, 43 nations said they thought DDT would be useful. But by 2015, 33 of those nations gave up DDT, due to insects developing resistance and immunity.
India, the sole remaining nation where manufacture of DDT occurs, plans to stop all DDT production by 2020. India discovered that more DDT makes the insect pests more resistant faster, instead of beating disease carriers.
This map from the UN Environmental Program shows declining use of DDT, 2000 to 2014.

One day dedicated to education and spurs to action to beat malaria.
Amazingly, there are ways to get it wrong. Please avoid them.
Don’t claim that all we need to do to beat this nasty disease is shoot environmentalists and poison the world with DDT. Don’t claim that health workers who risk their lives to prevent malaria with bednets, are misguided. No, Rachel Carson didn’t kill millions with false claims against DDT (in fact, she tried to keep DDT viable as a key tool to fight malaria, but we failed to listen to her in time).
You might kick in $10 to Nothing But Nets, and save a life in the most effective anti-malaria campaign in the last 50 years. In fact, I recommend it.
Have a thoughtful World Malaria Day.
