CAUSES OF ANIMAL EXTINCTION​

​1. forests have been cleared at astonishing rates

​=> species being killed in greater number than

ever before:

2. ​the replacement of grassland with croplands and urban areas

​=> exacerbates the risk of food security in developing countries in Asia and Africa, such as China, Vietnam and Egypt.

​3. increased demands for food from a growing global population

​=> due to a growing global population and rising incomes of individuals

EFFECTS​ OF ANIMAL EXTINCTION

• the decline in the number of wild bees and other insects, which help pollinating fruits and vegetables, could harm agriculture production

• ​Birds provide an important bellwether for tracking changes to the biospher

​

​=> without them, scientists cannot accurately predict weather patterns

• ​Man​y species offer insight into curing human disease/ hold the key to a number of medical breakthroughs

​

​

​=> Their disappearances could spell the end of humanity
