The Inquiry

In 2021 the president of Sri Lanka announced a total ban on chemical fertilizer and pesticides. The country’s farms were going to go fully organic. Health concerns were given as a reason, but in the background was the pandemic, loss of tourism and a lack of natural fertilizer available in the country. Sri Lanka is now in the worse economic crisis they have seen in decades and the government has reversed its ban on chemical fertilizer. This week on The Inquiry we explore why Sri Lanka’s organic farming dream failed.

Can scientists develop a vaccine which can combat the coronavirus and all its variants? There have been three lethal outbreaks caused by coronaviruses this century: SARS in 2002, MERS in 2012 and now SarsCov2. Scientists predict we will eventually encounter SarsCov3. That’s why the race is on to develop a universal vaccine to combat the coronaviruses and variants we know about, and the ones we have yet to confront. But attempts to create a universal vaccine for viruses such as influenza and HIV have been going on for decades - without success. Before 2020, proposals to create a vaccine against coronaviruses were not thought important enough to pursue since many just cause the common cold. Now that we understand their real threat, can scientists succeed in creating a vaccine to fight this large family of viruses?

On Wednesday 23 March the US administration declared that Russian troops had committed war crimes in Ukraine. It claims to have evidence showing numerous deliberate attacks on civilians. An unprecedented number of countries have backed an investigation by the International Criminal Court into the allegations. The evidence is being gathered.

Russia's military dwarfs Ukraine's by comparison, so it was expected that Ukraine would fall under Russian occupation quickly. One month later and Russia have made very little progress and Kyiv, the capital, remains under Ukrainian control. Given the overwhelming odds stacked against the Ukrainian military, why has the Russian military failed to conquer Ukraine?Charmaine Cozier takes a closer look at where the Russian military have made their mistakes.

According to media reports, Ukraine's president, Volodymyr Zelensky, has survived two assassination attempts from the band of mercenaries known as the Wagner Group.

Russia’s President Vladimir Putin has offered historical justification for his invasion of Ukraine by claiming its lands have long been part of Russia. The history of Russia and Ukraine may be intertwined, but the identity of Ukraine as a separate nation emerged over centuries, long before it became independent 30 years ago.
