Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: Please summarize the following article in two sentences.

Six people were hurt -- two critically — when part of a heating and ventilation system collapsed at a resort pool in Colorado on Saturday, fire officials said.

There were 50 to 100 guests in the pool when the collapse occurred at about 9:50 a.m. Saturday at the Gaylord Rockies resort near Denver International Airport, Aurora Fire Rescue said.

Large metal ductwork and mechanical parts that were mounted on the ceiling crashed down upon the pool deck and into the water, covering nearly the entire area of the pool, agency spokeswoman Sherri-Jo Stowell said.
Response: A heating and ventilation system collapsed at a resort pool that injured six people.  Large metal ductwork and mechanical parts crashed down in the pool area where 50 to 100 guests were in the pool.

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

Summarize the following information on the impact of deforestation in two sentences. Deforestation is the permanent removal of trees to make room for something other than forest. This can include clearing the land for agriculture or grazing, or using the timber for fuel, construction or manufacturing. Forests cover more than 30% of the Earth's land surface. Just over 20% of the Amazon rainforest has been cut down in the last 50 years. Removing trees deprives the forest of portions of its canopy, which blocks the sun’s rays during the day and holds in heat at night. This disruption leads to more extreme temperature swings that can be harmful to plants and animals.

Deforestation involves permanently removing trees for purposes like agriculture or construction, significantly reducing forest cover. This leads to more extreme temperature swings, harming plants and animals by disrupting the forest canopy.
