Everything! Try this lot to begin with:
- Trees give a home to three quarters of the Earth's animals and plant species a tree absorbs about a tonne of carbon dioxide over its lifetime here in the UK
- During the early years of it's life, a tree absorbs more carbon emissions
- In a year, one tree can produce enough oxygen for 10 people
- Trees replenish the earth with vital nutrients from the air
- Trees help to sustain a balanced Eco-system and bio-diversity
- Trees provide a sustainable source of timber used in many of our everyday objects
- They provide shelter from direct sunlight which can cool the ground temperatures
- Trees can reduce daytime temperatures by about 5 degrees, through shade and by evaporating moisture from their leaves
They're also brilliant for climbing, conkers and tree houses.
Nice.
