1.What is global warming?
• There is little doubt that the planet is warming. Over the last century, the planets temperature has risen by around 0.74 ± 0.18 °C. The warmest since the mid 1800’s was the 1990s. • The effects of global warming can have many unforeseen side effects.
The global warming also affects most of the animals.In the past, animals could adapt to gradual climate change by modifying behavior. Today, environmental pressures from growing human populations, along with the faster rate of climate change, make survival for many animals a big challenge
Let us begin to start energy saving and environment protecting, protect our survival homeland!
