What are the key drivers of extinction?

Habitat loss remains the main driver of extinctions, but it may act synergistically with other drivers such as over harvesting and pollution, and, in the future, climate change.

What are direct causes of extinction?

There are five major causes of extinction: habitat loss, an introduced species, pollution, population growth, and overconsumption. Through the activity, students will create a list of reasons why animals can become extinct.

What are the environmental drivers of extinction?

Students explore drivers of extinction, human and environmental, found within specific ecosystems of Earth’s major biomes by investigating habitat destruction caused by forces like climate change, parasites, greenhouse gases, and natural disasters.

How will extinction affect humans?

As species disappear, infectious diseases rise in humans and throughout the animal kingdom, so extinctions directly affect our health and chances for survival as a species. The rise in diseases and other pathogens seems to occur when so-called “buffer” species disappear.

Is disease a natural cause of extinction?

The extinction of any species is an irreversible loss of part of the biological richness of the Earth. Extinction can be a natural occurrence caused by an unpredictable catastrophe, chronic environmental stress, or ecological interactions such as competition, disease, or predation.

What will happen if extinction continues?

According to a study for the U.N., the continued loss of species could cost the world 18 percent of global economic output by 2050. Already, a number of industries have been economically impacted by species loss.

How can we prevent tiger extinction?

How will we get there?

1. Protect tigers and their habitat.
2. Build capacity in range states.
3. Reduce human-tiger conflict.
4. Conduct scientific research on tigers to help inform conservation strategies.
5. Promote tiger-friendly policies.
6. Monitor tiger numbers, population trends, and threats to tigers and their habitats.

How can we prevent Tamaraw extinction?

Conservation approach

1. Connecting organizations involved in Tamaraw conservation with other organizations and sources of funding.
2. Connecting local institutional stakeholders with relevant international partners and experts.
3. Promoting scientific work to better understand the ecology of the species and its habitat.

Who are the drivers of extinction on Earth?

Students explore drivers of extinction, human and environmental, found within specific ecosystems of Earth’s major biomes by investigating habitat destruction caused by forces like climate change, parasites, greenhouse gases, and natural disasters.

What are the main drivers of biodiversity loss?

Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4.3, S7). No single measure or indicator represents the totality of the various drivers.

Which is the number one cause of species extinction?

To summarize: on land, the number one driver of species extinction lies in changes in land use, and the number one reason for change in land use is agricultural expansion. Agriculture is, of course, both arable and pastoral.

What is the focus group for environmental drivers?

Environmental drivers focus group: Using the appropriate resources, have students gather evidence of environmental drivers’ impact on their species and its biome and record their response in Step 1 of Investigating an Endangered Species and its Biome.
