Although human species have lived on the planet at least 2.5 million years, economic development only appeared around the 1850s. In pursuit of economic development, not all nationalities have been equally lucky. Among more than 200 countries in the world, only dozens of countries are devel oped. Onethird of the world's total population of 6.5 billion are living in poverty. In both developing and developed countries, the wealth gap is often obvious. Therefore, eco nomic development is the goal of each country, the aim of each politi cal party, and the wish of all people. However, economic development usually baffles people. As a result, understanding the relationship be tween economic development and human rights protection is a matter of urgency.展开更多
