Wildlife is already being affected by global warming. You have to observe the basic trends of global warming. Deforestation is one of the biggest contributor to global warming and also affects wildlife as it leads to habitat destruction.
Species may not be able to adapt to this rapid climate change or to move fast enough to more suitable areas as their current areas become less suitable for them. Unless significant action is taken now, global warming will likely become the single most important factor to affect wildlife since the emergence of mankind.
