What would happen if the ecosystem collapse?

Ecosystem collapse can lead to catastrophic declines of carrying capacity and mass extinction, and can also pose existential risk to human populations. They provide recourses that are essential for life—air, water, food, shelter, and energy— and so their health inherently impacts the Earth’s habitability.

What happens if ecosystem is disturbed?

Whenever an ecosystem is affected by a substantial disturbance event, individuals and even entire species may be weakened or killed off. Other ecological damages can also occur, such as changes in hydrologic processes or soil contamination.

How do humans affect plants negatively?

Directly it reduces plant biodiversity throughout the destruction of natural habitats. … It is estimated that as many as several hundred species of animals, plants, and insects are lost every day due to deforestation and other factors.
