Explanation

Some ways to mitigate the effects of deforestation include planting trees, reducing greenhouse gas emissions, and protecting forests from development.

Multiple choice

How does the transportation sector contribute to deforestation and habitat loss?

  1. By constructing roads and infrastructure

  2. By increasing the demand for land for transportation purposes

  3. By fragmenting natural habitats

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The transportation sector contributes to deforestation and habitat loss by constructing roads and infrastructure, increasing the demand for land for transportation purposes, and fragmenting natural habitats. These factors collectively lead to the destruction of forests and other natural ecosystems, resulting in the loss of biodiversity and ecological imbalances.

Multiple choice

What is the primary cause of soil salinity in India?

  1. Excessive irrigation

  2. Poor drainage

  3. Deforestation

  4. Industrial pollution
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Excessive irrigation is the primary cause of soil salinity in India. When irrigation water is applied in excess, it can lead to the accumulation of salts in the soil, resulting in salinity.
