Question

Which out of the given options are environmental concerns ?  (i) Conservation of water  (ii) Disposal of waste  (iii) Increase of Population

Accepted Answer

The correct answer is: **4. (i), (ii) and (iii)**.

### Explanation:

All three options presented in the question are indeed environmental concerns:

1. **Conservation of water (i)**: Water is a vital resource for all forms of life. Over-extraction, pollution, and climate change are leading to water scarcity in many regions. Conservation efforts are essential to ensure sustainable water availability for future generations.

2. **Disposal of waste (ii)**: Waste management is a significant environmental issue. Improper disposal of waste can lead to pollution of land, water, and air, affecting ecosystems and human health. Effective waste management practices, including recycling and reducing waste generation, are crucial for environmental sustainability.

3. **Increase of Population (iii)**: Population growth puts immense pressure on natural resources, leading to overconsumption, habitat destruction, and increased waste production. It also exacerbates issues like food security, water scarcity, and pollution. Managing population growth is essential for sustainable development.

### Why Other Options are Incorrect:

1. **Option 1 (i) and (ii)**: This option excludes the increase of population, which is a significant environmental concern. Thus, it is not comprehensive.

2. **Option 2 (1) and (ii)**: Similar to Option 1, this option also omits the increase of population, failing to address all relevant concerns.

3. **Option 3 (ii) and (iii)**: This option excludes conservation of water, which is a critical environmental issue. By not including all three concerns, it does not provide a complete picture of the environmental challenges we face.

In conclusion, since all three options (i), (ii), and (iii) are valid environmental concerns, the correct answer is **4. (i), (ii) and (iii)**.
