what has led to the cultural erosion among black people and why are they following the western culture and rejecting the african culture

The question you've asked is complex and involves a number of factors. Here are some potential reasons:

1. Globalization: This is a major factor that has led to cultural erosion not just among black people, but across various cultures worldwide. Globalization has led to the spread of Western culture, including its values, lifestyle, and language, which are often seen as symbols of modernity and progress. This can lead to the adoption of Western culture and the gradual erosion of traditional cultures.

2. Colonial Influence: Many African countries were colonized by Western powers. During this period, African cultures were often suppressed and Western culture was imposed, leading to a long-term impact on the cultural practices of these societies.

3. Education: Western education systems have been widely adopted in many African countries. These systems often prioritize Western history and culture, which can lead to a lack of knowledge and appreciation for African culture.

4. Media Influence: Western media is dominant worldwide and often portrays Western lifestyle as desirable. This can influence people to adopt Western culture.

5. Economic Factors: Western countries are often seen as more economically developed. Therefore, people might associate Western culture with economic success and adopt it with the hope of improving their own economic status.

It's important to note that not all black people are rejecting African culture. Many are actively working to preserve and promote it. Also, culture is not static but evolves over time due to various influences. It's a natural process for cultures to influence each other. However, it becomes a concern when one culture dominates and erodes others.
