In the upcoming Olympic Games in July 2012, the British government faced many challenges to make the Olympics held securely.
Terrorist attacks are a major threat that must be faced by the British government.
But in addition to terrorist attacks, there is still another threat that haunts. The latest threats are hundreds of thousands of caterpillars that concern the health of the visitors.
Researchers in England say that the caterpillar plague could potentially arise in east London ahead of the Olympics. This moth larvae lodged in the oak trees there are many city streets.
Caterpillar covered with poisonous hairs, can trigger asthma attacks. If the exposed skin can cause skin burns and if entry into the mouth, could potentially trigger a sore throat, watery eyes, vomiting and dizziness.
Currently, local governments in collaboration with the Royal Botanical Garden and the British Forestry Commission to try to stop the spread of caterpillars. More than 700 moths had destroyed the nest, but the caterpillars kept popping up in the weather gets warmer.
Caterpillars first appeared in England in 2006. These larvae are carried while attached to the oak trees imported from the Netherlands. Since then, the numbers continue to grow in southeast England, to Reading and Sheffield.
