WASHINGTON: A leading Democratic presidential candidate in the US today said if elected to power he would work with countries like India and China to end dependence on fossil fuel to address the challenges being posed by climate change."I think the evidence is also out there that not only is climate change already causing devastating problems to this planet in terms of drought and flooding and extreme weather disturbances, if we do not transform our energy system, the situation will only become much worse, and obviously, it will impact human health," Senator Bernie Sanders , a Democratic presidential candidate said."So one of my top priorities as president of the United States will be to have this country lead the world, work with China or India or Russia, other countries, in breaking our dependence on fossil fuel and moving to energy efficiency and wind, solar, geothermal and other," Sanders said during a conference call.Responding to questions, Sanders said in a country which has massive levels of income and wealth inequality, it is absolutely imperative that we tell the wealthiest people in this country and the largest corporations and Wall Street that they are going to start paying their fair share of taxes.The Vermont Senator is currently ranked second among the Democratic presidential candidates, which is led by Hillary Clinton , the former Secretary of State and the First lady.Over the past few weeks, he has been drawing huge crowd nationwide, which analysts attribute here to his populist measures.
