Himalaya is facing the most danger from global warming. The snow caps have started to melt and so there are a huge change taking place in the path of the glaciers. The temperature of the Himalayas are rising 0.06 annually. This is causing a great damage to the snow cap peaks. 
Glaciers is still a looming concern for many scientists and governments, which worry about how warming will affect the region's water cycle. 
Lama has witnessed other changes in the road-less valley, 60km northwest of Kathmandu, where sure-footed ponies remain the quickest form of transport. "I feel that the sun is getting stronger, and in the past there used to be a lot more snow in winter. We used to get up to 2m in the winter, and it would stay for weeks. Last winter we only had 2cm."
Glaciers in the Himalayas are retreating at an average rate of 50 feet (15 m) per year, consistent with rapid warming  which was recorded at Himalayan climate stations since the 1970s. Winter stream flow for the Baspa glacier basin has increased 75% since 1966 and local winter temperatures have warmed up, suggesting increased glacier melting in winter. In winters also glaciers are melting to hear it is a shock for all the people, how can this be possible but it is true. This is showing that how much is it being affected. if it moves on in this way it will give rise to the chances of flood in the near by countries.
As Himalayan glaciers melt glacial lakes are swelling and in danger of catastrophic flooding. Average glacial retreat in Bhutan is 100-130 feet (30-40 m) per year. Therefore Bhutan is also facing the threat of the rising water level.
A time will come will all the glaciers will melt and the near by places will be under water.

Deforestation

Deforestation means the permanent destruction of indigenous forests and woodlands. At the same time it does not include the removal of industrial forests such as plantations of gums or pines, which are cultivated specially by the industries. Deforestation has resulted in the reduction of indigenous forests to four-fifth of their pre-agricultural areas. Indigenous forests presently covers only  21% of the earth's land surface.There are various consequences of deforestation.
"About one half of the forests that covered the Earth are gone. Each year, another 16 million hectares disappear. The World Resources Institute estimates that only about 22% of the world's (old growth) original forest cover remains "intact" - most of this is in three large areas: the Canadian and Alaskan boreal forest, the boreal forest of Russia, and the tropical forest of the northwestern Amazon Basin and the Guyana Shield (Guyana, Suriname, Venezuela, Columbia, etc.) "
 It is true that the way deforestation is taking place a time will come where thee will be only 1% of the trees will be left.  That will the end of the world.  Still the people are so casual towards it. It is not only about deforestation but also the impact it is having on the wildlife. The main effect is the loss of biodiversity and the loss of different type of species of animals. 
Brazilian deforestation is correlated with the economic health of the country, the decline in deforestation from 1988-1991 has matched the economic slowdown, while the rocketing rate of deforestation from 1993-1998 paralleled  with the Brazil's period of rapid economic growth. This was proved by a research. This shows that deforestation is also associated with the  economic growth of the country. 
Same is in case of India as in India there are still many group of people who earn their livelihood with the help of the forests. This has a vice versa effect as they cut down tress and sell them, this in turn causes deforestation. 
So, it is high time that we start to plant tress and try to protect the existing ones.

Wild Life Conservation

Human beings have started to think themselves as the most superior being and at the same time started to dominate the others. This is creating a huge difference which is a contemporary factor of causing environmental disaster. For that one first has to be aware of what is wildlife conservation. 
Wildlife conservation is a practice in which people attempt to protect endangered plant and animal species, along with their habitats. The goal of wildlife conservation is to ensure that nature will be around for future generations to enjoy, and to recognize the importance of wildlife and wilderness lands to humans. Many nations have government agencies dedicated to wildlife conservation which help to implement policies designed to protect wildlife, and numerous independent nonprofit organizations also promote various wildlife conservation causes.
Wild life can be conserved by providing them with natural environment and indiscriminate hunting and putting ban on illegal trade on wildlife products. “Every 20 minutes, the world adds another 3,500 human lives but loses one or more entire species of animal or plant life – at least 27,000 species per year.” (Source: PBS). “At the present rates of extinction, as many as 20% of the world's 7-15 million species could be gone in the next 30 years. This rate of extinction has been unprecedented since the disappearance of dinosaurs 65 million years ago.” (Source: WWF).
It is very sad to see that the number of exinct species have been increasing. With the passage of time people tend to forget it even. Why we don't think that what are we living behind us for the future generations. Though government has taken steps to conserve wildlife but it is not fully successful, as we all know.

Positive side of Global Warming

 The global warming is having some good effects on the nature also. The recent study proved that when on one hand the climatic change is effecting the life of the animals at the same time it is doing serving as a factor in increase the rain forests. 
Climate change, and associated shifts in temperature and precipitation, is having a varying effects around the world. Some forests will benefit from  this warmer conditions, increased rainfall, and carbon dioxide fertilization effects, while others will suffer from increased incidence of drought, fire, and pest outbreaks. It is having a dual effect. 
Though a research found that due to global warming new type of vegetation is coming up. These in turn is helping in increase the density of the forests. As the forests play an important role in reducing the pollution. It means that they are helping each other. The productivity of tropical forests is projected to increase where water is sufficiently available. Tropical forests, particularly rain forests, harbor the highest biodiversity of all land ecosystems; even moderate climate change would put some of this biodiversity at a considerable risk. 
What we can rather than hoping to a have some better future. Nothing can be done when people do things knowing the consequences. Still it is a good to get to hear that there are some positive sides of the global warming also, as we were tired of hearing only bad effects.
