Environmental health Unit 38 P1 Explain how human activity can damages the environment For years now we have been warned about human activity destroying our planet and environment. Some of the things that humans are affecting are Climate Change, Depletion of Ozone Layer, Pollution, Deforestation and Extinction of Species. Overcrowding, urbanisation and population growth Overcrowding can affect our planet more than some people think, Overcrowding means more people this means we use more natural resources this means the earth in the end isn’t going to have enough resources to support the growing population. Remember every person on the planet takes up space which could be used for farmland, and forests. People excrete wastes and litter that flow into water systems, and animal habitats, this is slowly polluting water and killing wildlife.
Factors of concern, such as ecosystem composition and pathogen virulence, are said to be related to climate changes. Climate change will have significant effects on wildlife, domestic animal, and human diseases, according to scientists. There is scientific agreement that the world’s climate is changing and that the evidence demonstrates that global warming and climate changes are happening. It is anticipated that continuing changes to the climate will have serious negative impacts on public, animal and ecosystem health due to extreme weather events, changing disease transmission activities, new and old diseases, and changes to habitat that are important to wildlife conservation. It’s very important to know that the majority of recent emerging diseases have a wildlife origin.
Drought has a serious impact on food productivity of a land, and even on the life expectancy of inhabitants. The aftermath of drought involves in socioeconomic, ecological issues (WGA, 1996) (Jeyaseelan, 2005; Pongracza et al., 1996). Iran encompassing drylands has been periodically jeopardized by drought events, which have devastatingly affected society and environment (Shamsipour et al., 2008). Therefore, the study of drought needs several sources of datasets. In other words, the design of a planning project for a region for sustainable development, the acquisition of updated data is critical, particularly for countries with arid to semi-arid climates.
Climate change: Fresh water is becoming increasing scarce in the future partly due to climate change. Climate change has a several impacts on these proportions, the main one being is that warming causes ice caps to melt which contaminate the freshwater supply. Over the next century, Africa will be at risk of experiencing decreases in water resources, especially in areas that are already water-stressed due to droughts, population pressures, and water resource extraction. As temperatures rise, snowpack is declining in many regions and glaciers are melting at unprecedented rates, increasing flood risks. Droughts are likely to become more widespread, while increases in heavy precipitation events would produce more flooding.

Global warming is the gradual increase of the Earth’s temperature due to greenhouse gases being released into the atmosphere. This change affects all species on Earth including humans, plants and animals. Global warming is responsible for the melting of glaciers, the loss of biodiversity, and the drastic climate change in the Arctic. The increase in the average global temperature causes the melting of glaciers and ice sheets.
Global warming has been a highly debated topic for quite a bit of time now. Is it or is it not happening? Global warming is an increase of temperature that causes related changes in climate and the environment. This has been seen in Antarctica especially. The change of temperature in Antarctica due to global warming has had many effects on wildlife and the environment already.
Since we have the attention of everyone, now is the best time to take action against global warming. Due to the increasing temperatures every year our public health and our agriculture/food supply is at high risk for new and worse diseases due to global warming; we need to change our climate control policies to protect ourselves. Gases are being trapped inside of earth’s atmosphere like a soda can, and are gradually increasing Earth’s temperatures that ice will start melting and there will be flooding due to rising sea levels; plants and animals will start becoming endangered (as cited in Cooper, 2001). We have already seen coastal flooding in parts of Central America and Bermuda’s forests are now endangered due to flooding (as cited in Clemmitt, 2006). Global warming has been an issue since factories were introduced to this world; gases and toxins are being highly exposed into our atmosphere causing a tremendous reaction to the balance of nature.
Issues such as whether households get enough food, how it is distributed within the household and whether that food fulfils the nutrition needs of all members of the household show that food security is clearly linked to health. Several factors that can cause food insecurity in the world today, that includes : Global Water Crisis - Water table reserves are falling in many countries (including Northern China, the US, and India) due to widespread overpumping and irrigation. Climate Change - Rising global temperatures are beginning to have a ripple effect on crop yields, forest resources, water supplies and altering the balance of nature. Land Degradation - Intensive farming leads to a vicious cycle of exhaustion of soil fertility and decline of agricultural yields. Greedy Land Deals - Corporations and Governments buying rights to millions of acres of agricultural land in developing countries to secure their own long-term food supplies.
How Cities Affect Climate Definition of climate change: |Main Entry: |climate change | |Part of Speech: |n | |Definition: |any long-term significant change in the weather patterns of an area | |Example: |Climate change can be natural or caused by changes people have made to the land or atmosphere. | As greenhouse gases build up, the earth’s climate is changing. Human activities are the cause of this. If this continues at this rate, droughts, floods and other types of extreme weather will become more constant and in turn could affect food supplies. There are many plants and animals that will not be able to adjust to these patterns and may become extinct.
The deglaciation of ice sheets and glaciers, which happens when we enter a interglacial warming period, are important because they have an immense impact on the land structure and vegetation throughout our continent, as well as the rest of the world. The deglaciation of the Wisconsin Glacier caused the formation of the Great Lakes as well as Niagara Falls in New York. This melting of ice sheets also causes sea levels to rise which covers landforms. The water submerges bridges and passageways between continents that were used by animals which migrated from continent to continent. This prevents certain species of mammals and plants from returning back to their native land, which drastically changes the vegetation and habitat of certain areas.
