I think the biggest threat to people and life on Earth in general nowadays is global warming. Doubtless, when we burn petrol, oil and coal, lots of carbon dioxide is added to the atmosphere that upsets the Earth's heat balance. If we keep emitting current greenhouse gas, climate change will cause about a third of the planet's animals and plants to face extinction by the middle of the century.
<span>"One morning Mr Sherlock Holmes was sitting in his room in Baker Street. His friend Dr Watson, was standing near the window looking at a walking stick.This stick had been forgotten by a strange visitor the day before. The words "To Dr Mortimer" was written on it. Dr Watson had already been examining it for half an hour but he couldn't say anything about it. Suddenly Sherlock Holmes said: The owner of this stick has a dog which is larger than a terrier. I have noticed the marks of a dog's teeth on the stick.' Probably the dog often carrys the stick behind the master,' he added. 'I wonder why this man wanted to visit us,' asked Dr Watson. 'Well, we shall soon know,' answered Sherlock Holmes. 'I can hear the bell ringing.' "</span>
