Impact of Global Warming on Animals

Loss of Habitat

As global warming causes climate change, many great deserts like the Sahara, are no longer able to sustain their animal population. Loss of habitat is most vividly seen in the Arctic, where global warming is melting the glaciers, pushing the polar bears into extinction, The melting glaciers have caused water levels to rise in many oceans, threatening to drown many tropical islands and forests, that teem with animal life.

Loss of Food

Grasslands are also adversely affected by global warming. The effects include high rate of evaporation, higher temperatures, frequent and severe droughts, reduced rainfall, and lower nitrogen content in forage grasses. Lower nitrogen concentration in the vegetation causes improper digestion in animals resulting in reduced strength, performance and health of animals.

To make room for an ever-growing population, many forests, grasslands, and even desserts, have been made habitable for humans. Rainforests and grasslands support many life forms, they are home to tiny insects as well as mighty, grizzly bears. When forests are cleared out to develop more land for domestic constructions, industrial reasons, and farming, most of these animals have to adapt themselves to live in shrinking areas, where everything is less, food,water, hunting and breeding grounds. Loss of habitats renders these animals vulnerable to being hunted down, either in their own little space, or when they come close to human habitats searching for food.

With deforestation, many trees and other plants, that provide food to herbivorous animals no longer exist, causing death due to starvation and malnutrition. This in turn has taken its toll on all other omnivorous and carnivorous animals too, making the entire animal life susceptible to extinction.Many animals, domestic or wild, who venture into the human habitat for food, eat from the garbage, mostly picking up plastic, rusted metal or contaminated food. This too has a devastating effect on their health.

Deforestation increases the Earth's temperature- 1

Deforestation increases the Earth's temperature Deforestation results in an increase in CO2 and other green house gases, which increases the Earth's temperature Trees plays a vital role in the equilibrium of the ecosystem. Deforestation is a process of cutting trees to make space for industries and households of the ever increasing human population. Excessive cutting of trees for urban use and other purposes are harmful to the environmental balance. It is needless to say that deforestation has several adverse effects on the environment. One of the major disadvantage of deforestation is that it disrupts the water cycle. Trees are responsible for drawing up water from the soil and releasing moisture into the atmosphere. Deforestation causes a disturbance in the water cycle and makes the environment drier. Climate change is a severe outcome of the excessive cutting down of trees. Forests lock up atmospheric carbon during the process of photosynthesis. Trees contain a m...

causes of global warming

What causes global warming? Global warming occurs when carbon dioxide (CO2) and other air pollutants and greenhouse gases collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth’s surface. Normally, this radiation would escape into space—but these pollutants, which can last for years to centuries in the atmosphere, trap the heat and cause the planet to get hotter. That's what's known as the greenhouse effect. the burning of fossil fuels to make electricity is the largest source of heat-trapping pollution, producing about two billion tons of CO2 every year. Coal-burning power plants are by far the biggest polluters. The country’s second-largest source of carbon pollution is the transportation sector, which generates about 1.7 billion tons of CO2 emissions a year. Reducing the amount of electricity generated from coal and gas and increasing the amount of electricity from clean, renewable energy sources like solar and wind, mea...

CAUSE - Aerosols

CAUSES OF CLIMATE CHANGE Aerosols Aerosols are less well-known than greenhouse gases. Aerosols are dust particles which, in addition to CO2, are released into the atmosphere in large quantities when wood and fossil fuels are burned. Some aerosols have a cooling effect on the climate, others have a warming effect. On balance they have a cooling rather than a warming effect, but no-one can give a clear idea of the magnitude, because we still do not understand how aerosols influence the occurrence and characteristics of clouds. Natural phenomena, greenhouse gases and aerosols create an imbalance in the incoming and outgoing radiation in the atmosphere. This process is known as Radiative forcing. When the earth heats-up, the short-wave radiation from the sun that enters the atmosphere is greater than the long-waves radiation that exists the atmosphere. The temperature changes on Earth will not stop until the radiation balance is restored. Given the immense capacity of ocean...
