Question

which of the following is not influenced by human activities 1. depletion of ground water 2. destruction of mangroves 3.increase extinctin rate of species 4. none of the above

Answer 1

All of these are being affected by the human activities.

 

• The excessive and unlimited use of water due to over population is causing water depletion.
• Humans are also removing thousands of acres of mangroves to make fields for rubber plants and rice paddies.
• Due to hunting, cutting of trees and destruction of forests, many species have been extinct or near extinction.

Thus, option 4 is correct.

Answer 2

Answer:

D) None of the above us the correct option.

Explanation :

• Numerous human actions undermine the environment's ability to function naturally and maintain balance.
• Deforestation and habitat loss have grown widespread, leading to a decline in the population of many species, and must be properly addressed.

Let's examine the available choices:

• A) Groundwater depletion: The water reserve found underneath the soil is known as groundwater. A number of human actions, including groundwater abstraction, misuse, reservoir construction, and land usage, have altered groundwater levels and contributed to its depletion. Thus, groundwater levels are being reduced as a result of human activity.
• B) Deforestation of Mangroves : Deforestation-related widespread destruction of mangrove forests has resulted in a decline in the number of mangroves. It is also brought on by activities like the building of dams, the disposal of industrial and sewage pollutants, and a decrease in the area occupied by wetlands. Therefore, mangroves are destroyed as a result of human activity.
• C) Increase extinction rate of species : A wide range of species have gone extinct as a result of habitat loss brought on by human activities such as deforestation and pollution. Many creatures have also been driven to extinction as a result of other activities like hunting and poaching. Therefore, species extinction rates have increased as a result of human activity.
• D) None of these : Since human activities have an impact on all of the aforementioned alternatives. Human activities have no impact on the aforementioned possibilities.
• Option D is the correct option when all the possibilities listed above are taken into account. In other words, none of the choices are impacted by human activity.
