What does human population have to do with natural environment?
The impact of so many humans on the environment takes two major forms: consumption of resources such as land, food, water, air, fossil fuels and minerals. waste products as a result of consumption such as air and water pollutants, toxic materials and greenhouse gases.
What is deforestation and why is it important?
Deforestation not only removes vegetation that is important for removing carbon dioxide from the air, but the act of clearing the forests also produces greenhouse gas emissions. The Food and Agriculture Organization of the United Nations says that deforestation is the second-leading cause of climate change.
What are the examples of land degradation?
Land degradation is the temporary or permanent lowering of the productive capacity of land (UNEP, 1992b).
What are the causes and effects of land degradation?
The two most significant direct causes of land degradation are the conversion of native vegetation into crop and grazing lands, and unsustainable land-management practices. Other factors include the effects of climate change and loss of land to urbanisation, infrastructure and mining.
How do humans modify the environment?
Human beings are modifying the natural environment by building factories, cutting trees, making dams, inventing objects like cars and air conditioners which pollute the air, polluting rivers and increasing activities which contribute to climate change.

How do humans cause deforestation?
Direct causes of deforestation are agricultural expansion, wood extraction (e.g., logging or wood harvest for domestic fuel or charcoal), and infrastructure expansion such as road building and urbanization. But roads also provide entry to previously inaccessible—and often unclaimed—land.
How are humans affected by deforestation?
Deforestation also degrades soil quality and is a major cause of the world’s rapid desertification. Such weather patterns and environmental changes contribute to the plummeting of the agricultural production. Humans are hit by food shortage due to the low agricultural produce.
How do humans affect land degradation?
Human interventions which are causing land degradation are (1) deforestation, (2) overgrazing by livestock, (3) mismanagement of agricultural land, (4) overexploitation of the vegetative cover for domestic use, and (5) (bio)industrial activities.
Which of the following human activities has made the greatest contribution to land degradation?
Deforestation means the cutting down of forests on a large scale so that the area is made suitable for non-forest uses such as the setting up of buildings, agriculture, and many more. Deforestation makes the soil infertile for any use therefore it causes droughts and land pollution.
What is the result of land degradation on human life?
Answer: Land degradation and desertification can affect human health through complex pathways. As land is degraded and in some places deserts expand, food production is reduced, water sources dry up and populations are pressured to move to more hospitable areas.
