Irreversible damages in the fauna.

Global warming is causing some irreversible damages in wildlife. There are longer and

more damaging wildfire seasons that destroy native terrestrial animal’s habitat. Additionally,

temperatures and sea level are rising bringing out the death of several sea species that depend on

ice for their survival. Besides, as changes between seasons continue to become less clear, many

flying species are mistiming their migratory pattern making them vulnerable to heat waves,

droughts or cold snaps. Moreover, the natural process of some species is being accelerated,

causing them to be born earlier and also having difficulties in adapting. All these environmental

phenomena might bring the worst consequences, for instance the extinction of some terrestrial,

aquatic and flying species all around the world.

Firstly, global warming has led to disastrous consequences in patterns of behavior in the

habitat, feeding changes and reproductive alterations in terrestrial animals. Early hibernation is

wreaking havoc in mammals. For instance, bears or woodchucks sleep three weeks less than they

did in previous decades. On the other hand, the impact of global warming affects the natural

habitats of animals by directly influencing their food chain. Thus, after the loss of seven hundred

and eighty five species declared extinct, many predatory animals are affected by the small

amount of food. Furthermore, due to the lack of rainfall, the natural environment does not

provide sufficient food for the species. Lately, the global warming is altering the length of

gestation in mammals. As a result, animals are giving birth to premature and weak creatures are

born with a high level of mortality due to lack of food.

Secondly, the continuous increase in temperatures and the destructive human intervention

has been impacting the lives of marine species in terms of habitat loss, the massive extinction

and the pollution of ecosystems. Nowadays, plenty of animals are victims of melting ice caps; as

a consequence, marine animals are losing the place where they live. Besides, they have to

migrate to cooler waters and adapt to a new habitat. On the other hand, many animals are being

directed toward extinction because they depend on ice for their survival. For instance, polar bears

are dying out as a result of immersion. Finally, coral reefs are being weakened by the pollution

of the waters, which is produced by the release of toxic substances in the ocean and the high

temperatures. Consequently, the various species that depend on ecosystems are dangerously

infected.

Thirdly, summers in different parts of the world have just come through the hottest years

in record and those which are more vulnerable and experience this abrupt change most

relentlessly are flying animal species. Birds fall out of the sky dead from heat; they are also

mistiming their migratory pattern because seasons have come less clear. When temperatures rise

flying species start to suffer, if these temperatures continue, the suffering goes on, leading to

organ failure and death, as a consequence of this, baby birds lose their mothers when they are

still dependent on them, both Mothers and babies are most likely to succumb. Many flying

species are dying over the course of days when temperatures rose to and above the critical

Celsius point, the numbers are not settle but if temperatures continue increasing a lot of flying

species may come to an end.

As a conclusion, we can say that global warming is irreversibly impacting the lives of

many species in different ways. For instance, this environmental phenomenon disrupts the

reproductive capacity and biological changes in animals; Moreover, it affects the rupture in the

food chain and on the loss of habitat for the terrestrial, marine and flying species. Nowadays,

seven hundred and eighty five species have been extincted; meanwhile, many animals are being

directed into massive extinction due to high temperatures and the human intervention.

Everyone has interrupted the natural cycle of animals; therefore, it is our duty to protect

all species. Thus, the number of endangered animals will be reduced and we could continue

appreciating the amazing fauna in our world.
