A biome is a geographical extensive ecosystem where all flora and fauna are found collectively. It is the total assemblage of plant and animal life interacting within the biosphere. Biomes are defined by abiotic factors like,relief, climate,soils and vegetation. They are classified into two broad categories,

1. Terrestrial biomes
2. aquatic biomes

Terrestrial Biomes

Terrestrial biomes is a group of living organisms that live and interact with one another on land. They are mainly determined by temperature and rainfall. Some of the major terrestrial biomes of the world are

A. Tropical Forest Biomes
B. Tropical Savanna Biomes
C. Desert Biomes
D. Temperature Grassland
E. Tundra Biomes

A. Tropical Forest Biomes

The tropical forest biome is comprised of several sub-biomes, including evergreen rainforest, seasonal deciduous forest etc.

Tropical forest have the highest biodiversity and primary productivity of any of the terrestrial biomes. The Amazon basin, Congo basin and Indonesian islands are the major regions of this biome. These regions have very dense forests and so have great economic importance. Human settlements are found scattered here. They sustain their livelihood through food gathering, fishing, lumbering and shifting cultivation. Due to the humid nature of this biome, the people get afflicted to tropical diseases like malaria, yellow fever etc. The chief trees found here are rubber, bamboo, ebony,etc. Bats, pheasants, jaguars, elephants, monkeys etc. are the important birds and animals found here.

B. Tropical Savanna (Grasslands) Biomes

Tropical grasslands are generally found between tropical forests and deserts. Tropical Savanna biomes are found between 10° to 20°N and S latitudes. These grasslands are generally flat and are found in the Sahel, south of Sahara in East Africa and in Australia. This biome is generally hot and dry and experiences moderate to low rainfall. So, the grass which grow here are tall and sharp. Hence the chief occupation of the people found here is herding. The primitive people living here are nomadic. The common animals found here are the lion,leopard, tiger,deer, red oats grass, lemon grass etc. are found in this biome.

C. Desert Biomes

Deserts are usually found on the western margins of the continents between 20° and 30° N and S latitudes. The annual rainfall is less than 25cm in these regions. Due to the lack of rainfall and arid conditions, these regions do not possess any vegetaion but have special vegetaion type called Xerophytes. As the soil is sandy and saline, deserts remain agriculturally unproductive. Drought resistant throny scrubs and bushes, palms are found here.

Tribal people who live here practice food gathering and hurting. They move their temporary settlements frequently in search of pasters. Transportation becomes very difficult here and is carried on by camels. Reptiles like snakes, lizards, scorpions etc., are most commonly found here.

D. Temperate Grassland Biomes

Temperate Grasslands are usually found in the interior of the continents and are characterized by large seasonal temperature variations, with warm summer and cold winter. The type of grassland in these regions strongly depends upon precipitation. Higher precipitation leads to talk and short and soft grass. These regions favour wheat cultivation. Extensive mechanised agriculture is practised due to lack of farm labour. Pastrol industry becomes the main occupation, thereby facilitating slaughtering of animals, packing of raw and processed meat, dairy products etc. The common birds and animals are grass hopper, wolf, bison, prairie dog etc.

E. Tundra Biomes

These vast lowlands are found where the ground remains frozen. Greenland, Arctic and Antarctic regions and Northern parts of Asia, Canada and Europe fall in this biome. These regions are also called Barren lands. This biome experiences long severe winter and short cool summer. Due to the prevailing of low temperature and short growing seasons, the net primary productivity is very low in tundra. People are nomadic. Hunting and fishing are their major occupations. The population here is extremely sparse and the harsh environment makes them change their settlement frequently. They live in igloos in winter and in tents during summer. Arctic moss, Arctic willow, lichens etc. grow here. Fauna like the polar bear, wolverine, reindeer, snowly owl are found here.

Aquatic Biomes

Aquatic biome is a group of living organisms that live and interact with one another and its aquatic environment for nutrients and shelter. Like terrestrial biomes, aquatic biomes are influenced by a series of abiotic factors.

1. Fresh water biomes
2. Marine biomes

A. Fresh water Biomes:

It comprises lakes, ponds, rivers, streams, wetlands etc. It is influenced by various abiotic components such as the volume of water, water flow, composition of oxygen, temperature,etc. Humans rely on freshwater biomes for drinking water, crop irrigation, sanitation and industry. Water lily,lotus, duck weeds etc. are the common plants found here. Trout, salmon,turtles, crocodiles etc. are the animals found here.

B. Marine Biomes:

They are the largest aquatic biomes on earth. They are continuous bodies of salt water and provide a wide range of habitats for marine plants and animals. Coral reefs are a second kind of marine biomes within the ocean.Estuaries, coastal areas where salt water and fresh water mix, form a third unique marine biome. As water provides maximum mobility to marine organisms, nutrients are circulated more quickly and efficiently here than the terrestrial biomes. Apart from animals, plants such as kelp, algae, phytoplankton etc. also grow in water. Aquatic biomes are not only important for plants and animals, but also for humans. Humans use aquatic biomes for water, food and leisure activities. Some of the threats and issues to aquatic biomes are overfishing. Pollution and rise in sea level.

Conservation

The biosphere extends from the deep ocean trenches to lush rain forests. People play an important role in maintaining the flow of energy in the biosphere. At the same time, the primary cause of today’s loss of biodiversity is habitat alteration caused by human activities. The ever increasing population results in over exploitation of biological resources. This has an adverse impact on flora and fauna on earth. There are places on earth that are both biologically rich and deeply threatened. Hence it is man’s duty to conserve and care for the earth and make it a better place to live in.

Celebrity worship syndrome (CWS) is an obsessive addictive disorder in which a person becomes overly involved with the details of a celebrity’s personal and professional life.

Celebrity worship for purely entertainment purposes is a perfectly healthy past time for most people. This type of celebrity worship involves harmless actions such as knowing and reading about a celebrity and following them on social media to know about their upcoming movies, music albums or sporting events. But apart from this, there are many different levels of celebrity worship that is harmful to themselves and those around them. The different classifications include simple obsessional, entertainment-social, intense-personal, love obsessional, and borderline-pathological.

• Entertainment-social

This level of admiration is linked to a celebrity’s ability to capture the attention of their fans. This can be following celebrities on social media, and knowing about their daily life. Although considered the lowest level of celebrity worship, it has been seen to have a number of negative effects like unhealthy eating tendencies, poor body image and low self-esteem.

• Simple obsessional stalking

This is not necessarily between a common person and the famous person with whom they are obsessed with. This case happens when a person has social awkwardness or low self-esteem and they feel inferior seeing someone they know personally, or a celebrity, for the confidence that they have. Such people bolster their own self-esteem by dominating and intimidating their mates. Exercising power over another gives them some sense of power in a world where they otherwise feel powerless. This is the most common form of obsession and it results in domestic violence in many cases.

• Intense-personal

This is an intermediate level of obsession that is associated with neuroticism and psychoticism. An example this would be, “I consider my favourite celebrity to be my soul mate”. It has been found that people who worship celebrities in this manner often have low self-esteem, especially if they think that the celebrity is physically attractive. People who have high levels of obsession are more accepting of cosmetic surgery than those who do not obsess over celebrities.

• Love obsessional

Individuals who demonstrate this sort of stalking behavior develop a love obsession with somebody who they have no personal relation to. The people that demonstrate this form of obsession are likely to suffer from a mental disorder, mainly schizophrenia or paranoia. Individuals that are love obsessional stalkers often convince themselves that they are in fact in a relationship with the celebrity. These are the cases where people have imaginary conversations and discussions with the celebrity they admire.

• Borderline-pathological

This classification is the most severe level of celebrity worship. It is characterized by pathological attitudes and behaviors. This includes spending tons of money on common items that were once used by the celebrity or even willingness to commit crime on behalf of the celebrity.

Although the media is not the only cause of CWS, it is the main reason for it to go to such dangerous extremes. The mass media is constantly bombarding people with images of glamorous lives of celebrities. The media is thankful for CWS and encourages it, as it gets more viewers, sells more products, and obtain more subscribers. In short, it makes money off of people who have CWS. Celebrity worship is not a new phenomenon. It is only reaching new terrible extremes because the media is coming up with innovative ideas to get people to obsess over celebrities.

Forests make up nearly 33% of the land area on our planet. 1.6 billion People rely on the benefits that forests offer, that include food, fresh water, medicinal herbs and shelter. Most o the world’s threatened and endangered animals live in forests.

Forests also counter the negative effects of climate change. They serve as carbon stores, taking in the carbon dioxide that would be left in the atmosphere.

Every year 58 thousand square miles are lost — the equivalent to one football field every two seconds. The study, from the nonprofit research organization Center for Global Development, predicts that as much as 2,890,000 square kilometers — or over a million square miles — of tropical forest could be lost to deforestation due to land being cleared for industrial agriculture. Jonah Busch, a coauthor on the report, said they found a pattern to the destruction.

“That amount of loss will have a big impact on the climate because trees store a lot of carbon,” Busch said, “and when they’re burned, and cleared for soy or beef pastures, or palm oil, all that the carbon that’s stored in the trees goes up to the atmosphere.” Busch and his colleagues estimated that 169 billion tons of carbon-di-oxide could be released, which is the annual quantity of pollution emitted from about fifty thousand coal-burning power plants. Busch also said that half of the projected deforestation could happen in Latin America, with the other half split between Asia and Africa.

The forest cover of the world will increase by at least 10 percent of its original value today in the next 5–10 years. A few countries will increase their forest cover drastically like northern parts of Africa and Mongolia. As far as the United States is concerned the forest cover has increased, at this point of time they have more trees now than what they had hundred years ago. The Indian and Chinese government will continue to implement their schemes unless they have reached their country’s goal. Hope other countries start to implement schemes and programs to improve their forest cover.
