The topics covered in the EVS (Environmental Studies) textbook are indeed relevant to the current environmental issues. Let's explore why:

1. Conservation of Natural Resources:
The textbook covers the importance of conserving natural resources such as water, air, and soil. This topic is highly relevant today as these resources are facing depletion and pollution due to human activities. Understanding the need for their conservation helps in addressing current environmental issues like water scarcity and air pollution.

2. Biodiversity and Ecosystems:
The EVS textbook educates students about the importance of biodiversity and the interdependence of organisms in ecosystems. With the increasing loss of biodiversity and the degradation of ecosystems, it is crucial to raise awareness about these issues. The textbook provides knowledge on the significance of preserving biodiversity and protecting ecosystems, which is relevant to the current environmental challenges.

3. Pollution and Waste Management:
The textbook discusses various types of pollution such as air, water, and soil pollution, along with the importance of waste management. These topics are highly relevant today as pollution levels are rising, leading to detrimental effects on human health and the environment. Understanding the causes, consequences, and preventive measures related to pollution and waste management is essential in tackling the current environmental issues.

4. Sustainable Development:
The concept of sustainable development is covered in the EVS textbook. It emphasizes the need to meet the present needs without compromising the ability of future generations to meet their own needs. This topic is extremely relevant in the current scenario as it addresses the challenges of balancing economic growth, social development, and environmental protection. Promoting sustainable practices is crucial for resolving environmental issues like climate change and resource depletion.

5. Climate Change:
