Habitat destruction

Construction of houses and infrastructure replaces natural ecosystems, directly destroying habitats and displacing wildlife.

Converting natural habitats into agricultural land for growing crops, such as palm oil plantations replacing rainforests, destroys the original ecosystem and reduces biodiversity. This also reduces habitat for insects like bees which rely on the rainforest plants for survival.

Large-scale livestock farming requires vast areas for grazing and growing animal feed, leading to deforestation and habitat loss.

Activities like mining, oil drilling, and logging directly remove or degrade habitats. For instance, open-pit mining destroys landscapes, and logging decimates forests and disrupts wildlife.

Pollution from industrial runoff, agricultural fertilizers, and sewage contaminates aquatic ecosystems, harming or killing aquatic life.

Habitat loss can eliminate key species from a food web, disrupting the flow of energy and nutrients and potentially causing the collapse of entire ecosystems.

Deforestation reduces biodiversity by eliminating habitats for numerous plant and animal species, leading to population declines and potentially extinction. The orangutans in Borneo are endangered due to deforestation.

Trees and vegetation help to absorb rainfall and reduce soil erosion. Deforestation removes this protective cover, leading to increased runoff, soil erosion, and a higher risk of flooding.

Trees absorb carbon dioxide during photosynthesis. Deforestation reduces the number of trees available to absorb carbon dioxide, and burning trees releases stored carbon, leading to an increase in atmospheric CO2, enhancing the greenhouse effect.

Tree roots bind the soil together, preventing erosion. Deforestation exposes the soil to wind and rain, leading to increased erosion and loss of topsoil, which is vital for plant growth. Topsoil erosion after deforestation can lead to desertification.
