How are humans affecting the Andes?

The average temperature of the Andes has risen by 0.7°C since the beginning of the 20th century, more than twice the global average. This is causing the glaciers in the Andes to melt at an alarming rate. The loss of ice is not only reducing water supplies for millions of people and livestock, but also creating natural hazards such as floods, landslides, and avalanches.

Mining and Deforestation

Mining and deforestation have long been two major sources of environmental degradation in the Andes. Mining activities can pollute water and air, as well as destroy habitats. Deforestation is another major problem, as it can lead to soil erosion and loss of biodiversity.

Overgrazing

Overgrazing by livestock is another major cause of environmental degradation in the Andes. Overgrazing can degrade soil quality, reduce vegetation, and lead to the spread of invasive species.

Unsustainable Agriculture

Unsustainable agricultural practices are also contributing to environmental degradation in the Andes. These practices can include the use of pesticides and fertilizers, which can pollute water and soil.

Urbanization

Urbanization is also having a negative impact on the Andes. As more and more people move to cities, the demand for resources such as water and energy is increasing. This can put a strain on natural resources and contribute to environmental degradation.
