What is the main reason that many species are becoming endangered?
Species become endangered for two main reasons: loss of habitat and loss of genetic variation. A loss of habitat can happen naturally. Dinosaurs, for instance, lost their habitat about 65 million years ago.
What are the reasons for endangered species of plants and animals?
Habitat loss is the primary cause of higher extinction rates. Other causes include habitat changes, over-exploitation of wildlife for commercial purposes, the introduction of harmful nonnative species, pollution, and the spread of diseases.
What are 5 ways that human activity reduces biodiversity?
But human activity is also having adverse impacts on biodiversity through overpopulation, overexploitation, habitat destruction, pollution, introduction of invasive species, and climate change.
Why are animals hunted?
One of the major threat to wildlife from us is hunting. Human beings have been using countless hunting methods since the begining. Earlier the main or rather the sole motive was to obtain food for survival. However nowadays hunting is used for incredibly large number of purposes and sadly also for fun.
What are the 5 causes of extinction?

What are the reasons for animals becoming endangered in India?
o The reasons they are an endangered species are accidental killing, entanglement in fishing gear, poaching for its oil and meat, river pollution, constructions of dams and barrages etc.
What are the effects of endangered species?
As species go extinct, they are taken out of the food chain. Animals that ate the newly-extinct species have to find new food sources or starve. This can damage the populations of other plants or animals. Furthermore, if a predator goes extinct, its prey's population can proliferate, unbalancing local ecosystems.
In what ways have population growth consumption of resources and technology impacted biodiversity and the nutrient cycles?
Population growth and increasing resource consumption affect biodiversity in two ways: they create pressure to convert wildlife habitat into agricultural and urban land, and they produce wastes that pollute habitat and poison wildlife.
How does industrialization and development affect biodiversity?
The major negative effects of industrialization on biodiversity are: (1) population growth and the consequent destruction of natural habitats, (2) the commercialization of society and the treatment of nature as a commodity, and (3) the increase in income disparity both within and among nations.
What are the 3 types of hunting?
Environmental philosopher Gary Varner identifies three types of hunting: therapeutic, subsistence, and sport. Each type is distinguished by the purpose it is meant to serve. Therapeutic hunting involves intentionally killing wild animals in order to conserve another species or an entire ecosystem.
Why are animals hunted and killed give two reason?
The most common reasons for humans to hunt are to harvest food (i.e. meat) and useful animal products (fur/hide, bone/tusks, horn/antler, etc.), for recreation/taxidermy (see trophy hunting), to remove predators dangerous to humans or domestic animals (e.g. wolf hunting), to eliminate pests and nuisance animals that …
What are 4 causes of extinction?
Habitat Loss; Overexploitation; Introduced Species; Global Pollution and Climate Change are all factors contributing to the extinction of species.
What are 2 causes of extinction?
Extinction occurs when species are diminished because of environmental forces such as habitat fragmentation, climate change, natural disaster, overexploitation by humans, and pollution, or because of evolutionary changes in their members (genetic inbreeding, poor reproduction, decline in population numbers).
What are the reasons for the destruction of wildlife?
The four most general reasons that lead to destruction of wildlife include overkill, habitat destruction and fragmentation, impact of introduced species and chains of extinction.
Why are animals losing their habitats?
What causes habitat loss? There are many causes of habitat loss, including land conversion for development from growing populations, mining for materials, harvesting lumber for paper products and, of course, agriculture.
What is the main reason that many species are becoming endangered Brainly?

Why do some animals become endangered Class 8?
Answer: Some animals become endangered because their population is already low. Also activities such as illegal hunting and deforestation further reduces their natural population.
Why are endangered species a problem?
Healthy ecosystems depend on plant and animal species as their foundations. When a species becomes endangered, it is a sign that the ecosystem is slowly falling apart. Each species that is lost triggers the loss of other species within its ecosystem. Humans depend on healthy ecosystems to purify our environment.
What are the 4 main causes of extinction?
What are the 4 main causes of extinction?
- Habitat loss and fragmentation.
- Over-exploitation.
- Alien species invasions.
- Co-extinctions.
How are nutrient cycles in terrestrial and aquatic ecosystems facilitated by microorganisms?
Microorganisms play a key role in nutrient cycling because they (1) decompose organic material (plant residues and soil organic matter) and release inorganic nutrients that can then be taken up by plants; (2) affect nutrient availability by solubilisation, chelation, oxidation and reduction; (3) store nutrients in, and …
What makes Philippines a biodiversity hotspot define what is a biodiversity hotspot?
Philippines: A Biodiversity Hotspot It is considered to be a mega – diversity country because of the exceptional diversity in ecosystems, species and genetic resources found within its 7,100 island territory.

How has industrialization resulted in acid rain and water pollution in Eastern Europe?
This coal pollution, which contains acid-producing chemicals, combines with moisture in the air and falls to the ground as acid rain. Polluted clouds drift away from the black triangle and other industrial areas and spread the pollution to forests in Northwestern Europe, degrading those environments as well.
What causes over hunting?
Overpopulation. The extensive increase in population every year has led to the encroachment of the forests by the people and hunters, that have increased the poaching and hunting activity, leading to overhunting.
