Indian police use tear gas to disperse farmers who were marching to the Indian capital after stopping them at New Delhi's border with neighboring Uttar Pradesh state, India, Tuesday, Oct.2, 2018. The farmers have been pressing for waiver of farm loans amid other demands. Rain-dependent agriculture employs more than half of India???s 1.3 billion people, but shrinking earnings mean it now accounts for only 15 percent of India???s economy. The bulk of Indian farmers are poor. (AP Photo), APTOPIX
