Economic activities and natural resources
Economic activities
Economic activities are what people do to earn a living
There are three groups of economic activities:
- Primary economic activities
* Jobs which involve working directly with the Earth’s rocks, soils and waters
* ==Example==: Farmers, Fisher, Forestry worker and Miner
- Secondary economic activities
* Jobs which involve making or manufacturing something
* ==Example==: Carpenter, Factory worker, Baker and Builder
- Tertiary economic activities
* Jobs which involve a service that is useful to people
* ==Example==: Teacher, Garda, Solicitor and Shopkeeper
Natural resources
Natural resources are in things in the natural world which are useful to people
There are two types of natural resources:
Renewable resources
- Can be used over and over again
- If looked after in a sustainable way they will never run out
- Also called infinite sources
- ==Example==: Water
Non-Renewable resources
- Can only be used once</li><li>Will eventually runout</li><li>Also called finite sources
- ==Example==: Oil
The use of natural resources is called exploitation. If they are over−exploited they might not be available in the future. Over-exploitation is unsustainable.
Water: a renewable
Potablewater: water that is safe for people and animals to drink
The water cycle
Water is continuously recycled making it a renewable resource. This recycling is called the water cycle. There are 4 main stages:
- Evaporation
* Occurs when the sun heats up water in lakes, rivers and seas and turns it into watervapour</li><li>Condensation
* The vapour rises into the air. As the air rises it cools and condenses to form clouds. The wind blows the clouds toward land.
- Precipitation
* This occurs when so much water has condensed that the air can’t hold it anymore. The clouds get heavy and the water falls back onto the Earth in the form of rain, hail, dew, sleet or snow</li><li>Run-off
* This water may go back into the seas, lakes or rivers or it may end up on land. When it falls on the land it will either soak into the soil or become part of the groundwater that plants and animals drink or it may runoff into the seas, lakes or rivers so the cycle starts again
Water in Ireland
Irish Water is responsible for the public water supply in Ireland.
Sustainable water exploitation in Ireland
Water is a very important naturalresource, so its very important to exploit it sustainably so there’s enough for the future generations

In 2015 world leaders agreed to worktogether to make sure that people around the world can live better without damaging the planet. Countries will work together to achieve the GlobalGoalsforSustainableDevelopment between 2015 and 2030
Irrigation
Some parts of the world experience shortagesofrainfall and drought. They use irrigation, the artificialwateroftheland.

Sustainable agriculture
Ireland is a member of the Eu’s Common Agriculture Policy (CAP). The main aims of the CAP are:
- Provide income to farmers
- Ensure guaranteed market prices in the EU
- Provide rural development programmes
- Supply the Europe with quality
In 2013 the CAP decided to focus on ‘Greening’. Farmers are rewarded for being more sustainable.
- Diversifying crops
- Farmers must keep permanent grassland
- Farmers must protect water sources on land
Forestry
The forestry industry employs 12,000 people. Wood is an important natural resource.
Types of Irish forest
Deciduous
Consists of trees that lose their leaves in winter:
Coniferous
Consists of evergreen trees:
Ireland forest
Ireland has the lowest forest cover of all European countries:
Impact of deforestation on the global climate
- Trees absorb Co²
* Green house gas => global warming
- Treesrelease O²
- MoretreeslessCo2
Reforestation in Ireland
Some places in Ireland are unsuitable for agriculture, so they are used for forestry
Coillte is a semi-state body and offers grants for farmers to plant more trees
