The discovery of America in 1492 changed world trade a lot, but it also brought many challenges:

1. Trade Routes Disrupted: The arrival of new resources from America messed up the old trade paths. This caused economic problems in Europe and Asia.

2. Exploitation of Colonies: Many native people faced serious issues because of colonization. This included slavery and the loss of their cultures, which raised big ethical questions.

3. Environmental Damage: New farming methods harmed the environment, leading to long-lasting effects on nature around the world.

4. Economic Inequality: The wealth from the American colonies mostly went to European countries. This made social and economic differences even greater.

Possible Solutions:

• Better Trade Practices: Creating fair trade programs could help make the global economy more equal.
• Sustainable Methods: It's important to promote farming that respects the environment and uses resources wisely for a stable future.
• Understanding History: By recognizing the wrongs of the past, we can develop better policies and work together with other countries.
