What are the disadvantages of globalization?

Globalization can be described as process of integrating cultural, financial, environmental and economical system on worldwide basis. It is a scenario where nations and countries from all around the world gets inter-connected for meeting their needs. These needs might be external or internal. It includes easy migration, advance transportation system, movement of capital between different countries and flow of services, finished goods and raw material.
The disadvantages of Globalization are listed below:
Globalization have created a gap between the rich and the poor. Poor people doesn't have that much access to the resources of the country because of the lack of science and technology in their lives on the other hand rich people are taking good advantage of globalization by application of technology and science.

Globalization has contributed greatly in increasing air pollution because of heavy traffic between countries. Poisonous gases are continuously releasing in the atmosphere and making it polluted.

Natural resources of earth also get affected because of the Globalization. There are large areas of forests and lands that are no more rich in minerals and other nutrients. Farming in those places are almost become impossible.

Small scale industries and local businesses have affected and suffered a lot as multinational national companies have taken place in their own country. The local companies are failed to compete with multinational companies and their counterpart.

The demand for skilled labour has increased in this global environment. Good opportunities for unskilled labour has decreased to a big extent.

Globalization is the interaction and connection of people from different parts of the world. It is encouraged by things such as international trade and information technology.
Some of the disadvantages of globalization are:
While globalization pushes for free trade, there still exist many barriers to free trade between countries. For example, many countries have taxes that are imposed on imports. These taxes increase the prices of imported commodities, thereby rendering them more expensive than the locally produced alternatives. This being said, however, if all barriers to trade were to be lifted, most poor countries would suffer as there would be an influx of higher quality commodities from the developed world into these countries, resulting in unfair competition.
Some multinationals take advantage of globalization to evade tax by exploiting tax havens that exist in other countries.
The increased use of technology that comes with globalization, while good in many ways, has had the counter effect of reducing the number of jobs that can be done by people.
Globalization has contributed to the erosion of local cultures in regions all over the world. For example, local African foods are fast being replaced by western fast foods like chicken and fries; western dressing styles trend over local styles in various communities. This has the effect of reducing the diversity of cultures.
Some multinationals misuse their workers in poor countries by offering them unfair pay or generally unfair working conditions.
Globalization can lead to the spread of infectious diseases across countries.
