what are the main factors responsible for causing ecological crisis?
310429
An ecological crisis occurs when changes to the environment of a species or population destabilizes its continued survival. Some of the important causes include: Degradation of an abiotic ecological factor (for example, increase of temperature, less significant rainfalls) Increased pressures from predation.

The main cause of the extinctions is the destruction of natural habitats by human activities, such as cutting down forests and converting land into fields for farming. Due to human activities, populations of many species have become small and isolated.

Global Warming and Climate Change These changes are directly and indirectly affecting all life forms. Pollution of air, land and water through excessive deforestation, industrialization and overfilling landfills which emits CO2 and adds to greenhouse gas emissions are all topmost causes of these environmental issues.

Abiotic factors may include space, water, and climate. The carrying capacity of an environment is reached when the number of births equal the number of deaths. A limiting factor determines the carrying capacity for a species.

Clearing habitats for agriculture is the principal cause of habitat destruction. Other important causes of habitat destruction include mining, logging, trawling, and urban sprawl. Habitat destruction is currently ranked as the primary cause of species extinction worldwide.

1. Loss of Habitat. The loss of habitats is the leading cause of wildlife extinction and a reason why so many animals are endangered. ... Without a habitat that can support their needs, lions are forced to venture into villages and kill the livestock communities rely on for survival.

As the population of the world is increasing at an alarming rate, the consumption of natural resources is also increasing. Hence, these resources should be conserved to maintain ecological balance and save them for future generations.

Land pollution is a major problem around the world and is caused by a variety of factors. Some of main causes of soil pollution include deforestation and consequent erosion, agriculture, industry, mining, landfills and illegal dumping of waste as well as urbanization and construction [8].

Deforestation and the destruction of forest habitat is the leading cause of extinction on the planet. ... On top of that, the capacity of forests to pull greenhouse gases from the atmosphere is lost as forests are cut. Forest loss contributes about 15-20% of all annual greenhouse gas emissions.
