It's true folks:
• Asthma rates for children fall 25% for every extra 350 trees per sq km.
• Money for a new Heathrow runway could provide 22m street trees.
• 1,000 new parks could help avoid 74,000 tonnes of carbon a year.
• For every 5% of tree cover added, water run-off is reduced 2%.
• A treeless street is 5.5C (10F) warmer than a tree-lined one in hot summers.
• Property in treeless streets is worth 18% less than buildings in roads that have trees.
So what are you waiting for, get planting and if you've already planted, get hugging :)
