manmade
Definition
Manmade means that something was created by people. It is the opposite of natural.
Manmade things can be made from a variety of materials, such as wood, metal, plastic, and glass. They can be made in a variety of ways, such as by hand, by machines, or by a combination of both.
Manmade things are important because they play a vital role in our society. They provide us with shelter, transportation, communication, and entertainment. They also help us to produce food and goods.
However, manmade things can also have a negative impact on the environment. They can pollute the air and water, and they can contribute to climate change.
It is important to be aware of the environmental impact of manmade things and to make choices that will minimize that impact.
How can the word be used?
The manmade disaster at the nuclear plant was a tragedy.
Different forms of the word
Adjective: Describing something that is made by humans. For example, you could say "manmade structures" or "manmade disasters".
Noun: Something that is made by humans. For example, you could say "the manmade environment" or "the manmade world".
Etymology
The word "manmade" comes from the words "man" and "made". The word "man" refers to humans, and the word "made" refers to the process of creating something.
The word "manmade" was first used in English in the 16th century. It was originally used to describe things that were made by humans, but it soon came to be used in a more general sense to describe anything that was created by humans, regardless of whether it was intentional or not.

What is the difference between natural and manmade?
AQA Science Exam Question and Answer
Question:
Explain the concept of manmade substances in the context of chemistry and provide an example of a manmade substance along with its significance.
Answer:
In the field of chemistry, manmade substances, also known as synthetic substances, refer to compounds or materials that are created through human intervention and manipulation of chemical reactions, rather than occurring naturally in the environment. These substances are intentionally designed and synthesised for specific purposes, often to meet human needs or to achieve desired properties.
An example of a manmade substance is polyethene, a widely used synthetic polymer. Polyethene is produced through the polymerization of ethylene monomers, which are derived from petroleum. It exists in various forms, such as low-density polyethene (LDPE) and high-density polyethene (HDPE), and finds applications in everyday products like plastic bags, bottles, and containers. Its properties, such as durability, flexibility, and resistance to chemicals, make it suitable for a range of industries.
The significance of manmade substances lies in their versatility and ability to address specific needs that natural materials might not fulfil. These substances contribute to advancements in technology, industry, and everyday convenience. However, it's important to consider the environmental impact of manmade substances, as some can be non-biodegradable and contribute to pollution. Therefore, responsible development and use of synthetic materials are essential to balance their benefits with potential drawbacks.
