1. Most plastics have strong corrosion resistance and do not react with acids or bases.
2. Low cost of plastic manufacturing.
3, durable, waterproof, light weight.
4. Easy to be molded into different shapes.
5, is a good insulator.
6, plastic can be used to prepare fuel oil and fuel gas, which can reduce the consumption of crude oil.

2, plastic is easy to burn, burning when the production of toxic gases.
3, plastic is made from petroleum refining products, petroleum resources are limited.

I know what you wrote down and its mean, and I can see the plastic is very cheap and its very durable and it's easy to molded into different shapes as well, so that's the good thing. And there are some bad things for example the plastic is easy to burn and Some harmful gases are released and the chamicals is bad for the soil it will into the soil but I think you haven't complete it because you haven't answer all the questions before I read you padlet I just know its bad for the environment but I don't know the specific reason. but now I know the chemical reason about that.

Jim:Thanks for your suggestionI talk  about it in the last padlet. You can learn information  from that padlet.If you want to learn more you can kick the website below.

I can understand your texts easily. The video tell me more about pollution in the ocean. It's hard to resolve and will kill the animal in the ocean.  I realize that  pollution is very terrible for our environment. We need to try to use less plastic bags. Keep ocean clean is a big mission to us.  I also know more about good things about the plastic. It's a good insutor and it's very cheap I think you can have more information about the chemical. I like your work very much ! Could you tell me does plastic bottle or plastic bags bad for our daily life or effect our body health? 
  
From Jim:
  • Plastic pollution does not directly harm people.It's step by step.First it will pollute water and soil . you know what will happened . Many vagetables will die.Then animals will die.Human will have nothing to eat.
  • If you want to know more about how does it hurts our body in chemistry you can kick the website below.

You really shows me a good padlet.

#1 Before I read your padlet, I only know that plastic can make by polyethylene, I didn't know that they can make by polyvinyl chloride. Because it is very bad to our health.

#2 I already know that plastic is very useful but also bad for the environment, but could you please tell me how it effects our body?

#3Your padlet form is very clearly, it makes me feelk very suitable. I can learn from it 




From Jim：Plastic pollution the first step is to pollute the environment, harm the body is indirect.Only when land and water are polluted, then plants and animals be harmed.And then finally people will be harmed.The website below will help you learn more
