Responses
Anything made in the lab requires natural resources to produce it.

The materials made in labs will still pollute the environment and destroy natural resources.
The main problem with the idea that natural resources could be saved if everything is made in labs is that the materials made in labs will still pollute the environment and destroy natural resources.
what is the answer
The answer is: "The materials made in labs will still pollute the environment and destroy natural resources."

In one to two sentences, explain a similarity and a difference between the particles in liquid water at 100ºC and the particles in steam at 100ºC. write YOUR OWN answer! (2 points)
The similarity between particles in liquid water at 100ºC and particles in steam at 100ºC is that both consist of water molecules. The difference is that in liquid water, the molecules are closely packed and have weaker kinetic energy, while in steam, the molecules are widely spaced and have higher kinetic energy.
You overhear a friend saying, “Plastic is the worst thing that humans have ever invented.”
In four to five sentences, explain whether you agree or disagree with your friend’s statement. Be sure to include facts that show the range of impacts that plastic has on human society and the environment.
(4 points) WRITE YOUR OWN ANSWER!
I partially agree with my friend's statement that plastic has had significant negative impacts on human society and the environment. On one hand, plastic has provided numerous benefits, such as its durability and versatility, making it widely used in various industries. However, the widespread use of plastic has led to detrimental effects. It takes hundreds of years for plastic to degrade, leading to an overwhelming accumulation of plastic waste in landfills and oceans. Plastic pollution poses a severe threat to marine life, with reports of animals getting entangled or ingesting plastic debris. Furthermore, the production of plastic contributes to greenhouse gas emissions, contributing to climate change. To mitigate these issues, it is crucial to reduce, reuse, and recycle plastic and encourage the development and use of more sustainable alternatives.
The correct answer is: The materials made in labs will still pollute the environment and destroy natural resources.
To arrive at this answer, we can evaluate each response option:
1. Anything made in the lab requires natural resources to produce it.
This option is not the main problem with the student's idea because it acknowledges that natural resources are necessary to create lab-made materials. However, it does not address the main problem.
2. There are not enough synthetic resources yet to make what people need.
This option is not the main problem with the student's idea because it simply states that there is a lack of synthetic resources. While this may be a challenge, it does not address the main problem.
3. People might think it is fine to waste a lot of the materials since they just came from a lab.
This option discusses the potential behavior of people when using lab-made materials, but it does not address the main problem of the idea itself.
4. The materials made in labs will still pollute the environment and destroy natural resources.
This option correctly identifies the main problem with the student's idea - lab-made materials may still contribute to pollution and the destruction of natural resources, despite being produced in a controlled environment.
Therefore, the correct answer is: The materials made in labs will still pollute the environment and destroy natural resources.
