Snowball Earth

If an earthquake’s epicentre is near a forest, it may knock trees down. When this happens, it allows sunlight to penetrate the canopy, which allows the growth of different types of plants. Tress reduce the amount of carbon dioxide on the earth by changing the carbon dioxide into oxygen therefore, if tress fall down, the amount of carbon dioxide will increase causing global warming. if earthquakes are on the seafloor then they affect the plates there - sediment changes and gas release. Plus…

visually indistinguishable from humans, and are exclusively used for menial or dangerous work on off-world colonies. Replicants are banned from earth, if one of them managed his way to earth, blade runners will be sent to hunt them and then retire (kill) them. Deckard, who is a blade runner, has the mission to retire four replicants who have got to earth to find a way to live longer. As the film goes on, it is difficult to notice if Deckard really is the hero or if he is just doing his job;…

Introduction Ozone depletion has been regarded as one of the global environmental issues for several decades. It is defined by Martens (1) as the situation that the amount of stratosphere ozone layer is decreasing and being damaged. The major reason is that the ozone in the stratosphere protects us from the harmful ultraviolet radiation and absorbs heat from the infra-red radiation. Reducing the amount of ozone probably causes irreversible and permanent damages to human and environment,…

Modern spaceflight is something that is wondrous to many people. It is an important topic mainly because advancements made in this field could determine the future of the planet and the human race. The main question on this topic is who should be leading the effort to explore the cosmos, private persons and companies or governmental institutions? Although the modern day space initiative is being mostly spearheaded by private persons and industries, in my opinion, government funded space programs…

are the primary cause of global warming in the present day. In short, these are gases that are capable of trapping radiation and preserving it inside of Earth’s atmosphere. The most abundant greenhouse gas is water vapor. As the atmosphere of the Earth warms, the quantity of water vapor…

INTRODUCTION Surface waters are the natural water resources that are found on the earth’s surface, such as oceans, rivers, lakes or dams etc(Chen, Teng et al. 2013). These water resources become polluted in many different ways. And when this happens is called the surface water pollution, which occurs when hazardous substances come into contact with the water resources (Chen, Teng et al. 2013). These water resources are important for drinking, domestic use and recreational purposes; however they…

The term Climate change is a reference to any meaningful alterations in the measures of climate that takes place over a long period of time. Climate involves substantial changes in temperature, rainfall or wind that arise over numerous decades or more. The term is sometimes applied to particularly refer to changes in climate that are caused due to human activity, in contrast to changes that may have occurred in climate due to the Earth’s usual processes. In this particular sense, especially…

Livestock production and climate change affect and get influenced by each other. The most important effects of climate change on the environment and livestock include rise in temperature, elevation in sea level, alteration in microbial eco-system and several others effects, known or unknown which might affect the livestock positively or negatively. There have been various predictions about the quantum of sea level rise with varying degree of confidence because many of the natural phenomena have…

The effects of climate change are felt across the world with temperatures rising and snow and ice being less apparent in colder countries. The effects of climate change are prominent on the outside, however, what many people fail to realize is that it affects the ocean too, temperatures are rising and not only that but the ocean chemistry is changing as well due to increased amounts of carbon dioxide dissolving into the ocean. This leads to several complications in the coral reef ecosystems. The…

The atmosphere is a clear odourless gas that envelopes the Earth, held together by gravity. Everyone on the planet has the right and access to the atmosphere, making it a global common. There are many components that make up the atmosphere, the main components is nitrogen, which makes up 78.09% of the atmosphere, and oxygen, which makes up 20.95%. Around 1% of the atmosphere is comprised of water vapour, methane, carbon dioxide, sulphur, argon and particulates (e.g. dust). There are a total of…
