Positive impacts of Green Revolution:
1. Increased food production: The Green Revolution led to a significant increase in food production, which helped to feed the growing population.
2. Improved crop yields: The use of high-yielding varieties of crops and modern farming techniques resulted in improved crop yields.
3. Reduced hunger and poverty: The increased food production helped to reduce hunger and poverty in developing countries.
4. Increased income for farmers: The higher crop yields meant that farmers could sell more produce and earn more money.
5. Reduced pressure on natural resources: The increased productivity of crops reduced the need to clear more land for farming.

Negative impacts of Green Revolution:
1. Environmental degradation: The intensive use of chemical fertilizers and pesticides led to environmental degradation and soil erosion.
2. Dependency on technology: The Green Revolution created a dependency on technology and expensive inputs, which made small farmers vulnerable to market fluctuations.
3. Increased inequality: The Green Revolution favored large-scale farmers and agribusinesses, leading to increased inequality and displacement of small farmers.
4. Health hazards: The use of chemical fertilizers and pesticides has been linked to health hazards, including cancer and other chronic diseases.
5. Loss of biodiversity: The focus on high-yielding crops led to a loss of biodiversity, as traditional crop varieties were replaced with modern ones.

Extra Question: What are the current challenges facing the Green Revolution?

Some of the current challenges facing the Green Revolution include:

1. Climate change: Climate change is increasing the frequency and intensity of extreme weather events, making it difficult for farmers to predict planting and harvesting cycles.

2. Soil degradation: The intensive use of chemical fertilizers and pesticides has led to soil degradation, reducing soil fertility and productivity.

3. Water scarcity: Many regions are facing water scarcity, making it difficult for farmers to irrigate their crops.

4. Biodiversity loss: The focus on high-yielding crops has led to a loss of biodiversity, reducing the resilience of agricultural systems.

5. Food waste: A significant amount of food is wasted each year, which puts pressure on the environment and wastes valuable resources.

Positive impact of green revolution :
1. This helps the farmers to produce crops in surplus amount.
2. The production of crops were increased after using modern methods.

Negative impact of green revolution :
1. It decreases the fertility of the soil.
2. It also make the ground water dirty and poisonous.
