Answer:
We might lose things such as plastic bags, water bottles cardboard and glass it would be a shame if any of these things got lost we could be using the glass to help us build structures or we can even build things out of plastic and we can try helping people by building gains Lego blocks to craft out a house for them.
An organism must has a large surface area to volume ratio in order to exchange material easier
in animals erythrocytes have a flat concave shape that allows them to carry more haemoglobin and also increases its surface area to volume ration so that the length and availability of a surface is less for the materials to travel
multi cellular organisms tend to have flat and elongated respiratory surfaces to allow for a higher surface area to volume ratio in order to increase the rate of gas exchange
the ilium in most mammals is flat and elongated and is covered with microvilli to increase surface area and to reduce the cells volume therefore reducing its surface area to volume ratio
hope that helps
