Introduction to Natural Resources
Unit 1 introduces the natural resources that sustain all life on Earth – forests, water, food, minerals, and energy. This unit covers both their importance and the serious problems arising from their overexploitation. Understanding resource depletion is the first step to advocating for sustainable solutions in the pharmaceutical industry and beyond.

Frequently Asked Questions (FAQs)
Q1. What is the difference between Renewable and Non-Renewable Resources?
Renewable resources can be naturally replenished within a relatively short period (e.g., solar energy, wind, water, forests).
Non-renewable resources (e.g., coal, petroleum, minerals) exist in finite amounts and cannot be replenished once exhausted.
Q2. What are the main causes of Deforestation?
The main causes include:
Logging for timber
Clearing land for agriculture (shifting cultivation)
Urbanization
Mining activities
Construction of dams and roads
Q3. What are the effects of Deforestation?
Deforestation leads to:
Loss of biodiversity
Disruption of the water cycle
Soil erosion
Increased CO₂ levels (contributing to climate change)
Desertification
Displacement of tribal and indigenous communities
Q4. What are the advantages of Renewable Energy?
Renewable energy sources (solar, wind, hydro):
Are inexhaustible
Produce little or no greenhouse gas emissions
Reduce dependence on fossil fuels
Are becoming increasingly cost-competitive
Q5. What is Desertification?
Desertification is the process by which fertile land gradually turns into desert due to factors such as overgrazing, deforestation, drought, or improper irrigation practices, leading to severe soil degradation.
