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: Summarize the main points of this article about forests.

Here is the article you'll use:
Dry forest
Dry forests are found in warm climates where seasonal droughts last for several months at a time. Deciduous trees predominate these forests, and during the drought a leafless period occurs, which varies with species type. Tropical and Subtropical Dry Forests are found in southern Mexico, southeastern Africa, the Lesser Sundas, central India, Indochina, Madagascar, New Caledonia, eastern Bolivia and central Brazil, the Caribbean, valleys of the northern Andes, and along the coasts of Ecuador and Peru.
Latin American dry tropical forests are some of the most endangered on earth. 
Response: Dry forests exist in drought-ridden, warm climates with various deciduous trees. There are tropical and subtropical variations throughout southeastern Africa, South America, the Caribbean, central India, and other locations, although those in Latin America are some of the most endangered. 

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.

Outline the main points about the significance of coral reefs according to the following passage.

Coral reefs are diverse underwater ecosystems held together by calcium carbonate structures secreted by corals. They are often referred to as the 'rainforests of the sea' due to their rich biodiversity. Coral reefs protect coastlines from wave action and storms, support fisheries, and are valuable to tourism. They also host species that are sources of new medicines. However, coral reefs are threatened by climate change, pollution, and destructive fishing practices, necessitating urgent conservation efforts.
