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. And the more the population grows the more wasted were going to produce and cause pollution and damage to the environment. More housing and buildings being built means that were building over were habitats live, the loss of these forests leads to extinction of plants and animals. Also more people means that more goods (like clothes, TVs etc) are wanted, more jobs are needed so more factories are being built witch is affecting out air pollution, which eventually is destroying out atmosphere. Also more food is required so more intensive farming methods are used. Transport system Transport systems can have many bad effects on the environment, one of them being exhaust emissions, the more populated area the higher the emissions. Also when a car for example breaks and has to be scraped if parts of the car are not properly disposed of like the oil and battery it can cause lots of damage to air pollution and the environment. Also Transport infrastructure (such as roads or parking spaces) covers 25-30 per cent of land in most
