Which is correct?
A. People live longer because better medicines and cleaner water stop the spread of disease. The air is also the cleanest it has ever been
A. Fewer babies die, and people live longer because better medicines have wiped out most diseases

Which is correct?
A. As world population increases, less land is needed for agriculture (for food) and building (for homes, business & industry)
A. As world population increases, forests are cut down as wood is needed for building, perfumes and plastics
A. As world population increases, more land is used for agriculture (for food) and building (for homes, business & industry). Forests are cut down as wood is needed for building, furniture and paper. Habitat is lost and less carbon dioxide is removed from the atmosphere
A. As world population decreases, more land is used for agriculture (for food) and building (for homes, business & industry)
Which is correct?
A. Farming has increased habitat for wildlife everywhere in the world
A. Herbicides and pesticides have allowed habitats to support more plants and animals in the countryside
A. Pesticides have killed many species of bird, but the number of birds has risen dramatically over the last 50 years
A. Farming reduces habitat for wildlife. Herbicides and pesticides have also killed plants and insects which are food for butterflies and birds
Which is correct?
A. Bird and butterfly populations have risen over recent years
A. Bird and butterfly populations have fallen over recent years
A. Bird populations have fallen over recent years, but butterfly numbers have increased
A. Butterfly populations have fallen over recent years, but bird numbers have increased
Which is correct?
A. Animals and plants breathe in carbon dioxide and this is how they obtain their energy
A. Animals and plants are both able to photosynthesise and this is how they obtain their energy
A. Photosynthesis is a process used by plants to make carbon dioxide, which is one of the foods they need for energy
A. Photosynthesis is a process used by plants to make sugar, which is one of the foods they need for energy
Which is correct?
A. Fertilisers wash into rivers and lakes causing water plant numbers to increase
A. Herbicides wash into rivers and lakes causing water plant numbers to increase
A. Pesticides wash into rivers and lakes causing water plant numbers to increase
Insecticides wash into rivers and lakes causing water plant numbers to increase
Which is correct?
A. Quarries which extract the raw materials for building, increase habitat for wildlife.
A. The creation of brand new buildings means that less rubbish needs to be put into land fill sites
A. Quarries which extract the raw materials (non-renewable resources) for building, reduce habitat for wildlife. More building and more people also means more rubbish for landfill sites
A. Quarries extract renewable resources from the earth. These raw materials are used for building
Which is correct?
A. Most of the world’s population lives in rural and farming communities. Big cities are, however becoming more common
A. Most of population live in cities, which import most of their food, fuel, building materials and water. Cities also produce more waste per person than rural communities which tend to be more self-sufficient
A. Rural communities produce more waste per person than cities. This is largely due to agricultural waste
A. Rural communities and cities produce roughly the same amount of waste per person
Which is correct?
A. Hydroelectric power plants (HEP) are built to supply electricity in places which are rich enough to afford them, rather than the cheaper coal fired power stations
A. Hydroelectric power plants are built to supply electricity, but they also have the effect of increasing habitat for wildlife
A. Hydroelectric power stations supply cheap electricity, and have little effect on the landscape
A. Hydroelectric power plants are built to supply electricity in places which are too poor to import fossil fuels. HEP dams cause flooding, which destroys more habitat
Look carefully at the graph on Page 1 and say what approximately was the population of the world in 1925.
Assuming the population of the world today is 7.8 billion and that in the year 2100 the high estimate is 15.6 billion calculate by what percentage (%) will the world's population have grown between 2020 and 2100. (Show your working out.)
