Burning and mining coal for fuel is harmful to the environment but because how cheap and easy it is to find many people are unwilling to give it up as a fuel source. One of the problems with coal is that they are limited and are non-renewable so once it has been used we won’t be able to use it again. When coal gets burned they start to release harmful dangerous toxins such as mercury, lead and arsenic that will then escape into the air. It also releases large amounts of carbon dioxide (CO2) into the atmosphere. These emissions increase the greenhouse effect in the atmosphere and lead to global warming. The benefits: Coal mining can benefit humans as well as it supports the economy in many ways. Coal mining provides a lot of jobs for local communities. It provides over 7 million jobs worldwide. Waste incineration units produce a lot of carbon dioxide gas approximately around one third of the greenhouse gasses. It also impacts people’s health as they get exposed to the toxic emissions by breathing in the air or consuming contaminated food and water. Additionally, when the garbage gets burnt by the incinerators they end up as ashes which are then emitted from the chimneys, including the toxic materials and end up in specialist landfill sites for hazardous waste. The benefits: The waste incineration benefits us because as we burn the waste it creates energy to heat our homes and generate electricity. Task 3- Naturally damaging Earthquakes (Tectonic plates)- They are the earth’s crust; they move very slowly every year. As the tectonic plates slide over each other they cause earthquakes. Earthquakes produce various damaging effects this includes damage to structures of buildings, bridges and other standing formations which then... ... middle of paper ... ...rn them and that’s how we generate electricity however, we are also adding carbon dioxide into the atmosphere which is a major concern for our planet. We can start reducing the use of fossil fuels by moving to renewable energy sources these include: • Wind • Sun • Hydro • Tidal and wave • Geothermal • Biomass • Biofuel People can also reduce the use of fossil fuels by doing simple things for instance switching off lights and appliances when leaving the room. Walking or cycling instead of driving a car or use public transport for maybe longer journeys. Little things like this will make a big difference, making our planet a better place. Pesticides in farming Instead of using pesticides in farming a better alternative would be biological control. This is when a natural predator is released into the crop growing area as a result the number of pests can be reduced.
