Question

Explain why less trash is left on Earth when people recycle bottles and cans?

Answer 1

This is because recycled materials have already been refined and processed once; manufacturing the second time is much cleaner and less energy-intensive than the first.

Step-by-step explanation:

Answer 2

Bottles & cans (the ones made of plastic especially) account to about ⅔rd of the waste generated all over the globe. Also, plastic & glass bottles/cans are non-biodegradable & hence, persist on the surface of the Earth for longer years than biodegradable substances as biodegradable substances can be easily digested by the enzymes in the decomposers but this can't be done in the case of non-biodegradable substances. If these are recycled instead of being dumped then we can reduce this waste & also help in its less production thus making the Earth a green & safe planet.
