Disturbing the environment is like disturbing the world's living creatures, which could cause their extinction. The environment contains oxygen, the most important thing for all living things. Apart from this, it contains food, water, a place to live and nature to relax which creates a satisfying environment for them. We have a lot of natural luck to use, but using it carefully is an essential thing. Forests are the home of wild animals as they consume their needs, so if we deforest them, it could create a big problem for the animals. They lose their properties and the result is extinction or starvation of food. Deforestation encounters numerous problems such as drought, global warming, cavity in the ozone layer, land degradation which leads the world to severe calamities. Drought creates the problem of food hunger and poverty. Global warming raises temperatures to high levels, which causes the death of living beings. The planet is warming, from the North Pole to the South Pole, and everywhere in between. Worldwide, mercury is currently more than one degree Fahrenheit, and especially in the more insensitive polar districts. Furthermore, the effects of rising temperatures will not hold in the distant future. They are happening right now. Signs appear everywhere, and some of them are surprising. The heat is not only softening the glacial masses and sea ice, but is also causing precipitation phenomena and causing animals to advance (2014, National Geographic Society). Carbon dioxide is one of the gases responsible for global warming because it decreases the level of oxygen. Secondly, the most harmful gas is CFC (chlorofluorocarbons), which is more harmful than carbon dioxide because it reduces the thickness of the ozone layer which causes global pollution.
