Some important threats to the environment due to over exploitation of ...
Obviously the answer is D. The reason can be explained as follows,
1.Due to over use of land for agriculture, mining, construction the quality of the land will be reduced which is called land degradation.
2. Due to deforestation and over grazing and also poor soil protection remedies soil erosion takes place.
3. Over irrigation and removal of vegetation leads to landslides.
4. Due to occurrence of all the above mentioned problems desertification takes places(which means leaving a particular geographical area).

Some important threats to the environment due to over exploitation of ...
Threats to the environment due to over exploitation of land resources:
There are several important threats to the environment that arise due to the over exploitation of land resources. These threats have significant negative impacts on ecosystems, biodiversity, and human well-being. The following statements are true and form important threats:
(i) Land degradation:
Land degradation refers to the loss of productivity and functionality of the land. It occurs when the natural characteristics and quality of land are negatively altered, often due to human activities such as deforestation, unsustainable agriculture, and mining. Land degradation leads to decreased soil fertility, reduced water holding capacity, and increased vulnerability to erosion, among other consequences. It has severe impacts on food security, water availability, and the overall health of ecosystems.
(ii) Landslides:
Landslides are another significant threat resulting from the over exploitation of land resources. When the natural stability of slopes is disturbed, often due to deforestation, mining, or construction activities, it can trigger landslides. Landslides can cause loss of life, damage to infrastructure, and disruption of ecosystems. They also contribute to the erosion of soil and sedimentation of rivers, leading to further environmental degradation.
(iii) Soil erosion:
Soil erosion is the process by which soil is removed from its original location and transported to other areas. Over exploitation of land resources, such as unsustainable farming practices, deforestation, and improper land management, accelerates soil erosion. This results in the loss of fertile topsoil, reduced agricultural productivity, and increased sedimentation in rivers and lakes, leading to water pollution and habitat degradation.
(iv) Desertification:
Desertification refers to the degradation of dryland ecosystems, primarily caused by human activities and climatic variations. Over exploitation of land resources, such as overgrazing, deforestation, and unsustainable agriculture, accelerates the process of desertification. It leads to the loss of vegetation cover, soil degradation, and the expansion of arid and semi-arid areas. Desertification has severe socio-economic impacts, including the displacement of communities, loss of livelihoods, and increased poverty.
Therefore, all the given statements (i), (ii), (iii), and (iv) are true and represent important threats to the environment resulting from the over exploitation of land resources.
