Fragmentation in terms of the reduction in environment is the process of land being broken down into fragments. Deforestation is one of the most prevalent problems in modern history, as the depletion of trees in the natural environment has began to pose great consequences and environmental risks.

"A carbon footprint is an estimate of the climate change impact of activity – such as making a product, living a lifestyle or running a company" (theguardian.com). Normally, the carbon footprint is not only measured in CO2 emissions of an activity, but also including other greenhouse gasses such as methane and nitrous oxide. These factors are added together and expressed in terms of a carbon dioxide equivalent (CO2e); the amount of CO2 that would (theoretically) create the same amount of warming.

The 'lifecycle assessment' is the standard way of calculating the carbon footprint; it involves adding up as many of the emissions pathways as possible. Another way to measure the carbon footprint is the 'input-output' analysis. This method involves adding up the total emissions of a country or region, then dividing it in different sectors (clothes manufacturing, food growing etc.) and obtaining the amount of emissions for each sector. Estimations can then be made for each sector's carbon footprint.

The ozone hole is an area in the stratosphere above Antarctica where chlorine and bromine gases from human-produced chlorofluorocarbons (CFCs) and halons have destroyed ozone molecules.

Global warming is the rise in average global surface temperature caused primarily by the build-up of human-produced greenhouses gases, mostly carbon dioxide and methane, which trap heat in the lower levels of the atmosphere.

The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere. By having it, it keeps the earth warm enough surface to keep an optimal temperature for life.

There are many sources for the pollutants, but the most significant ones are for example From region to region, there are significant variations in the relative importance of nutrient sources. IN addition to that, the amount of nitrogen in the air got tripled in the last decade, making it even harder for animals to breath under water

Eutrophication arises from the oversupply of nutrients, which leads to over growth of plants and algae. After such organisms die, the bacterial degradation of their biomass consumes the oxygen in the water, thereby creating the state of hypoxia.

When algae die, they decompose and the nutrients contained in that organic matter are converted into inorganic form by microorganisms. This decomposition process consumes oxygen, which reduces the concentration of dissolved oxygen. The depleted oxygen levels in turn may lead to fish kills and a range of other effects reducing biodiversity. Nutrients may become concentrated in an anoxic zone and may only be made available again during autumn turn-over or in conditions of turbulent flow.

Factors:

Improvement in Public Health eg Hygiene(Washing hands, Going to the doctor when one didn't feel well ect.)

Medical Knowledge(Medical Science eg knowledge of the human body, knowledge of vaccines

Food Production Distribution eg Rice farms produced a lot of food in a short amount of time, this would then feed the whole village. However as villages became bigger more food was needed and space was running out. This was when food trade came into place and villages could keep expanding.

Atmospheric pollution - How it is formed, examples of atmospheric pollution:

# data[].attributes.body
Atmospheric pollution, or air pollution, is the introduction of harmful particulates, biological molecules or chemical molecules into the Earth’s atmosphere.

Sources

Burning of fossil fuels: Sulphur dioxide emitted from the combustion of fossil fuels like coal, petroleum and other factory combustibles is one the major cause of air pollution. Pollution emitting from vehicles including trucks, jeeps, cars, trains, airplanes cause immense amount of pollution.

Agricultural activities: Ammonia is a very common by product from agriculture related activities and is one of the most hazardous gases in the atmosphere. Use of insecticides, pesticides and fertilisers in agricultural activities has grown quite a lot.

Consequences

Global warming: Another direct effect is the immediate alterations that the world is witnessing due to global warming. With increased temperatures world wide, increase in sea levels and melting of ice from colder regions and icebergs, displacement and loss of habitat have already signalled an impending disaster if actions for preservation and normalisation aren’t undertaken soon.

Acid Rain: Harmful gases like nitrogen oxides and sulphur oxides are released into the atmosphere during the burning of fossil fuels. When it rains, the water droplets combines with these air pollutants, becomes acidic and then falls on the ground in the form of acid rain. Acid rain can cause great damage to human, animals and crops.

Effects on Humans: Migration and refugee crisis - people moving from where they originally live to gain better access to water, food and health resources.

Effects on Humans and Nature: flooding, wild fires, heat waves, droughts, and stronger hurricanes and typhoons - force people to move from where they are living to escape these disasters, food and water sources are limited or entirely depleted - ruin the environment and break up the ecosystems in areas affected by these natural disasters.

Effects on Nature: Breaking up of the ecosystem and natural environment - animals and plants will go extinct

The different transportation techniques emit greenhouse gasses, such as carbon dioxide, which contribute to global warming.

Air pollutants and matter from waste can be deposited in the soil and surface waters where they enter the food chain. These substances can affect the reproductive, respiratory, immune and neurological systems of animals.

Nitrogen oxides and sulfur oxides are major contributors to acid rain, which changes the pH of waterways and soils and can harm the organisms that rely on these resources.

Factors such as food, water, nutrients, and space need to be there in order for the human race to survive. For example, if food starts running out then the human population will decrease. If the population gets too big, then the human race will start to decrease.

Carbon footprint
A carbon footprint is defined as: The total amount of greenhouse gases produced to directly and indirectly support human activities, usually expressed in equivalent tons of carbon dioxide (CO2). The carbon footprint of a household increases with some basic daily activities, such as transportation, using diesel powered cars and the use of electricity coming from a coal powered power plant.
