Polar Ice Caps

Image
Ice is melting at the poles. Impacts will be global. Ice shelves are massive, floating platforms of ice that surround the ice-covered continents of Antarctica and Greenland. When they melt, sea level isn't directly affected because this ice is already in the ocean. But scientists have learned that floating ice shelves act as dams to glaciers, which are flowing rivers of ice. After the Larsen B Antarctic ice shelf broke up in 2002, glaciers behind the shelf began flowing into the sea much more quickly. Movement of ice from land into the ocean makes sea level rise globally. Why are glaciers important? Ice acts like a protective cover over the Earth and our oceans. These bright white spots reflect excess heat back into space and keep the planet cooler. In theory, the Arctic remains colder than the equator because more of the heat from the sun is reflected off the ice, back into space. Glaciers around the world can range from ice that is several hundred to several thousand years old an...

Loss of Biodiversity

Image
Biodiversity loss, also called loss of biodiversity, a decrease in biodiversity within a species, an ecosystem, a given geographic area, or Earth as a whole. Biodiversity, or biological diversity, is a term that refers to the number of genes, species, individual organisms within a given species, and biological communities within a defined geographic area, ranging from the smallest ecosystem to the global biosphere. (A biological community is an interacting group of various species in a common location.) Likewise, biodiversity loss describes the decline in the number, genetic variability, and variety of species, and the biological communities in a given area. This loss in the variety of life can lead to a breakdown in the functioning of the ecosystem where decline has happened. Bleached Coral Seascapes The idea of biodiversity is most often associated with species richness (the count of species in an area), and thus biodiversity loss is often viewed as species loss from an ecosystem or...

Depletion of Natural Resources

Image
The depletion of natural resources occurs when resources are consumed at a faster rate than that of replacement. Natural resources are those resources that are in existence without human actions and they can either be renewable or non-renewable. And when it gets down to the discussion of natural resource depletion, it a terminology used in reference to water usage, farming, fossil fuel consumption, fishing, and mining. And above all, natural resource depletion is defined on the premise that the value of a resource is measured in terms of its availability in nature. A resource that is rare on earth due to depletion has a higher value than a natural resource which is in abundance. Due to the increasing global population, the levels of natural resource degradation is also increasing. Consequently, the world’s eco-footprint is estimated to be one and a half times the ability of the earth to sustainably provide each individual with enough resources that meet their consumption levels. Herein...

Over Population

Image
In the past fifty years or so, the growth of the population has boomed and has turned into overpopulation. In the history of our species, the birth and death rates have always been able to balance each other and maintain a population growth rate that is sustainable. Since the time of the Bubonic Plague in the 1400s, the growth of the population has been on a constant increase. Between the time of the plague and the 21st century, there have been hundreds and thousands of wars, natural calamities, and man-made hazards. What is Overpopulation? Overpopulation is an undesirable condition where the number of the existing human population exceeds the actual carrying capacity of Earth. Overpopulation is caused by a number of factors. Reduced mortality rate, better medical facilities, depletion of precious resources are few of the causes which result in overpopulation. It is possible for a sparsely populated area to become densely populated if it is not able to sustain life. Growing advances in...

Climate Change

Image
Climate change includes both global warming driven by human-induced emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. Though there have been previous periods of climatic change, since the mid-20th century humans have had an unprecedented impact on Earth's climate system and caused change on a global scale. What is climate change? Climate change is generally defined as a significant variation of average weather conditions -say, conditions becoming warmer, wetter, or drier over several decades or more. It's the longer-term trend that differentiates climate change from natural weather variability. Record floods, Raging storms, Deadly heat, Climate change manifests itself in myriad ways and is experienced by every living being, although not equally.   What will climate change means? People Climate change will transform the way we live, causing water shortages and making it harder to produce food. Some regions could become dangerously hot and ...

Environmental Conservation

Image
Human existence is quite impossible without the presence of a healthy ecosystem. Our environment comprises all living and non-living components and their interactions within a natural habitat. Environmental conservation has become one of the core issues that need to be addressed to battle climate change and global warming. Sustainable development is the need of the hour which can save the mother earth from the repercussions of industrialization. In this blog, we will aim to elaborate upon environmental conservation, its needs as well as methods. What is Environmental Conservation? Environmental conservation is the practice of us humans saving the environment from the loss of species, and the destruction of the ecosystem, primarily due to pollution and human activities. Conservation is vital in saving and helping both animals and trees as we are all dependent on one another for survival. Trees convert carbon dioxide produced by factories into oxygen, which helps us breathe and respire. ...
