The Silk Road was a way Europe and Eastern Asia spread their cultures and beliefs. As the biggest trading route, many cultures and beliefs were passed around. It started in China and the reason it's name is the "Silk" road is because China was trading silk and other textiles on this route. It stretches to every part of Europe, Middle East, and Eastern Asia. Now it is used to spread religion, food, clothes, music, etc. The whole continent became a melting pot because everyone was trading cultures and beliefs around.
The greatest negative impact of colonization was the exploitation of the natural resources by foreigners which did not benefit the local communities, but instead the colonizers
The colonial governments introduced improved medical care, and better methods of sanitation.
