Explanation: Increased mechanization has reduced the need for labor, is the right answer. In the period between 1850 and 1900 very significant changes took place in agriculture in the United States.

It can lead to serious health issues, including stunted growth, eye problems, diabetes and heart disease. Malnutrition affects billions of people worldwide. Some populations have a high risk of developing certain types of malnutrition depending on their environment, lifestyle and resources.

Drier climates are best suited for livestock ranching. This answer has been confirmed as correct and helpful.

Which of the following statements best characterizes changes to agriculture in the United States since 1900? Increased mechanization has reduced the need for labor.

Ukraine is most suited to farming.

greenhouse gas emissions. Biodiversity is negatively affected by both damming and deforestation.

Deforestation refers to the decrease in forest areas across the world that are lost for other uses such as agricultural croplands, urbanization, or mining activities. Greatly accelerated by human activities since 1960, deforestation has been negatively affecting natural ecosystems, biodiversity, and the climate.

Causes for Deforestation:

• Agriculture: Conversion of forests to agricultural land to feed growing needs of people.
• Commercial logging:
• Mining:
• Increase in population:
• Urbanization and industrialization:
• Construction of dam reservoirs:
• Forest fires:
• Overgrazing:

When the forest trees are cut down,the percolation of rain water into soil is reduced. A lot of rain water from deforested soil rushes into the rivers quickly,causing floods. Deforestation decreases the water holding capacity of soil which leads to floods. The eroded soil is carried by flowing rain water into rivers.

Loss of nutrients in the soil that are derived from breakdown of tree leaves. Increased soil erosion by wind and rain. Increased flooding due to a lack of water absorption by trees. Decreased ability to support other plants due to nutrient loss.

It means clearing or cutting of trees or forests over large area. Forests are cut so that land can be used for different purposes like building houses,making roads etc.

The planting of trees in an area in which forests were destroyed is called reforestation. The planted trees should generally be of same species which were cut down from the forest during deforestation. We should plant at least as many trees as have been cut down. This is called natural reforestation.

What are the causes and consequences of deforestation? Forests are cleared in order to obtain land for urbanisation and industrialisation. Forests are destroyed to clear land for cultivation of crops and cattle grazing. Trees are cut down to be used for firewood.

Clearing of forests(by cutting down forest trees)over a wide area is called deforestation. The various causes of deforestation are: 1)They are cut down to obtain wood for using fuel. 5)The forest trees are cut down to get land for building houses,factories,roads and dams.

Reforestation (occasionally, Reafforestation) is the natural or intentional restocking of existing forests and woodlands (forestation) that have been depleted, usually through deforestation, but also after clearcutting.
