As our Earth's temperature warms up because of climate change, it is having unexpected effects on our world's forests. When temperatures rise, trees close their skins to 1 the loss of water, and this, in turn, slows down the 2 of photosynthesis(光合作用). As a result, these trees are shorter and grow slowly, as well as have a 3 death rate.
Climate change also increases the 4 of droughts and wildfires. After wildfires, it takes a while for the forest systems to 5, and in some cases, the forests are 6 permanently. Trees that are stressed are also 7 to attacks by bacteria(细菌). In tropical forests, vines that use the trees as 8 can often choke the trees and rob them of nutrients. Finally, humans have 9 the forest landscape through logging. When trees are replanted on the soil, they will never grow as large as the 10 trees that were cut down.
As these forests disappear, species that once called them "home" are forced to change, 11 the variety of those systems. 12, some endangered species are unable to 13 and die. Old-growth forests are disappearing in all regions of our world. When forests die, younger forests that are reestablished in the same area grow back weaker and smaller 14 poor vegetation(植被). With trees dying increasingly and continuously, will future generations 15 out on the wonders of forests?
