Animal Extinction; Why & How

Play a mini game! Extinction

Climate Change and its Affect on Animals

Bumblebees


- Rising Temperatures force populations of bees to remain in cool climates

- Spring flowers bloom earlier than normal

- There is less time for bees to pollinate

Whales


- Whales rely on ocean temperatures for their migration, feeding, and reproductive habits

- As the temperatures of the ocean rises, their habits necessary for survival are disrupted

Asian Elephants



- Lower rainfall and higher temperatures affect Asian Elephants

- These threats have decreased the reproductive capacity of Asian Elephants

Giraffes


- The Giraffe population has declined by 40% in the last 30 years

- Poaching has contributed to this population decline

- Their habitat and major food supply (acacia trees), are shrinking due to climate change

Incects


- At the current rate of warming (2°C), roughly 18% of all incect species would be lost by 2100

- If this warming rate were to rise to 3.2°C, the extinction number would rise to 49%

Oceanic Birds


- These birds are affected by rising sea levels

- Rising waters can submerge their costal habitats and nests completely

Sharks


- Sharks have difficulty hunting and a higher embryo mortality rate with the rise of ocean acidity and temperature

- These rising temperatures force sharks northward by an average of 30km anually

- This disrupts ecosystems that are dependent on sharks

Coral Reefs


- Coral reefs are sensitive to temperature

- In the last 3 years, 72% of the worlds coral reefs protected by UNESCO experienced severe heat stress

- This heat stress causes coral bleaching, which is when coral starves from a loss of nutrition

Monarch Butterflies


- Monarch butterfly populations in California have declined by as much as 95% since the 1980s

- This decline is due to habitat loss, more frequent use of pesticides, and loss of milkweed populations

Great Apes of Southeast Asia



- Great Apes of Southeast Asia are the most endangered ape species

- They are facing extinction due to deforestation as nearly 75% of forest cover is at risk for deforestation
