(a) If we go on cutting trees, it will cause - deforestation

(b) If an animal's habitat is disturbed, it will cause - animals to become endangered and eventually extinct.

(c) If the top layer of soil is exposed, it will cause - soil erosion.


Consequences of deforestation:

Deforestation leads to climate change, soil erosion, flooding, desertification, loss of biodiversity, food insecurity, increment in the greenhouse gases in the atmosphere, loss, and extinction of species, changes in weather patterns and climate, and an increase in conflict among humans and wildlife.


Effect of deforestation on the following areas are:

(a) Wild animals: Deforestation lost the natural habitat of the animals and it can also lead to their extinction.

(b) Environment: Deforestation causes global warming in the environment and causes an adverse effect on the ecosystem.

The plants are responsible for the absorption of carbon dioxide and releasing oxygen into the atmosphere, and their absence will result in the accumulation of carbon dioxide gas.

(c) Villages (Rural areas): Villagers and tribals are one of the stakeholders of forests. They obtain fuel, fruits, wood, etc. from forests.

Deforestation reduces these available resources, and freely moving uninhabited animals also pose a danger for the villagers.

(d) Cities (Urban areas): Although, city people are not directly affected by deforestation, climate change caused by deforestation is responsible for various calamities such as floods, droughts, tsunamis, etc.

(e) Earth: Deforestation removes the fertile land's green cover and converts it into a desert. It leads to climatic change and natural calamities.

(f) Next Generation:  Due to the harsh climatic conditions and increasing global warming caused by deforestation, many animal and plant species are on the verge of extinction. The next generation might not be able to obtain a glimpse of beautiful and attractive flora and fauna.
