Summarize the main ideas presented in the following passage about the environmental impact of plastic pollution:

Plastic pollution is a global environmental crisis that poses severe threats to ecosystems and human health. Plastic production and usage have increased exponentially since the 1950s, with millions of tons of plastic waste entering the oceans each year. These plastic materials take hundreds of years to decompose, breaking down into smaller and smaller particles known as microplastics. Marine life is particularly vulnerable, as they can ingest or become entangled in plastic debris, leading to injury, starvation, and death. Microplastics have also been found in drinking water, seafood, and even table salt, raising concerns about potential impacts on human health. Addressing plastic pollution requires a multi-faceted approach, including reducing plastic consumption, improving waste management systems, and promoting sustainable alternatives to single-use plastics.

The main ideas are: 1) Plastic pollution is a severe global environmental crisis impacting ecosystems and human health. 2) Millions of tons of plastic waste enter the oceans each year, breaking down into microplastics that can be ingested by marine life and humans. 3) Plastic debris poses threats to marine life through ingestion and entanglement, leading to injury, starvation, and death. 4) Microplastics have been found in drinking water, seafood, and table salt, raising concerns about human health impacts. 5) Addressing plastic pollution requires reducing plastic consumption, improving waste management, and promoting sustainable alternatives to single-use plastics.

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: Can you give me a summary of why it is harmful to use weight loss drugs?

Here is the article:

Weight loss drugs have soared in popularity in the past year, helping some lose dramatic amounts of weight — but not all that weight is fat. 

Some of that is actually lean mass, which is everything in the body that isn’t fat, including your bones, organs and, importantly, muscle. 

“When we look at weight reduction from any intervention, about one-third of the weight we lose tends to be lean mass, and that can be problematic,” said Dr. Jaime Almandoz, an associate professor of internal medicine in the Division of Endocrinology at UT Southwestern Medical Center in Dallas. That lean mass loss is generally from muscle. “Lean mass is healthier and associated with better metabolism, so when we lose lean mass, we may lose some of that function.”

The more muscle mass a person has, the better the resting metabolic rate, or the number of calories a person burns at rest. When a person loses muscle mass, the resting metabolic rate decreases, too.
Response: Utilizing weight-loss drugs can be harmful. They help an individual lose weight quickly, but some of that weight comes from healthy lean body mass. Lean body mass is important because it helps bolster metabolism, which is how many calories the body burns at rest.

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.
