Unit 38: Environmental Health
How human activity can affect the environment and human health.
There are loads of different ways that we as humans affect the world and the environment we live in. Some things that we do can not only change and affect the environment but can also affect our health.
Urbanisation is caused by people inhabiting the cities and towns moving away from rural areas. This can be a problem because it causes Overcrowding, waste accumulation, transport systems.
Overcrowding is where too many people are in the same area. This can cause diseases like colds to spread because of cross infection.
When there are too many people in one place they all contribute to waste. Waste can attract pests which can carry and spread diseases.
Transport problems in urban areas can cause stress. For example if people are unaware of their bus numbers or if the bus is late, they can become stressed. Transport systems can also cause accidents and make people physical disabled.
Another human activity is intensified agriculture. This is when farmers have to produce loads of food in a small area and small amount of time. They use pesticides which could end up in food if it is not cleaned before consumption. This could affect human health or even poison them.
Intensified agriculture can also destruct wildlife habitats. This can happen because farmers need more land to make more crops. They end up killing the homes for many wild life creatures.
Monoculture is also an environmental problem. This is because the soil losses its fertility and recovery time. This makes it difficult to grow other crops. This can lead to hungry people and a bad season for the farmer. Pollution is a really big problem there are four different types of pollution air, water, land, and noise. They affect are health in different ways. Air pollution is caused from CO2 carbon dioxide. Carbon dioxide is a waste product from burning fossil fuels like oil and coal. As most cars run off petrol you can understand why CO2
