Question

Explain any three such changes causing destruction to the ecosystem.

Mention three causes of destruction of ecosystem.

Answer 1

1. Infrastructure Development - The construction of roads, flyovers, and bridges disrupts the existing land usage pattern, placing a strain on our resources. These developments contribute to the degradation of our ecosystem.

2. Deforestation for Urban Expansion - To accommodate urban growth, the widespread cutting of trees has become a common practice, disturbing climatic conditions. This deforestation has led to irregular rainfall and extreme temperatures in the current scenario.

3. Overgrazing Impact - Cattle utilize land for grazing, and overgrazing has negative effects on the ecosystem. This practice results in the depletion of vegetation cover, leading to issues such as soil erosion, reduced soil fertility, and desertification.

Answer 2

Causes of Destruction of Ecosystem:

1. Construction of dams results in deforestation which reduces the forest cover.
2. Urbanisation leads to clearing of forests and fertile lands for human settlements.
3. Mining operations also destroy the ecosystem. They often contaminate the soil with toxic heavy metals and acids.
