Thousands of Polish farmers took to the streets of Warsaw on February 27 carrying the national flag and blowing handheld horns, escalating a protest which started in early February against food imports from Ukraine and EU green rules. Farmers across Europe have been protesting for weeks against constraints placed on them by the EU's 'Green Deal' regulations, which are meant to tackle climate change, as well as rising costs and what they say is unfair competition from outside the EU, particularly Ukraine. The Polish farmers rallied in central Warsaw before marching toward parliament and then the prime minister's office.
