Deforestation is a physical change that has harmful effects on the environment. It leads to loss of biodiversity, disruption of ecosystems, increase in greenhouse gas emissions, and soil erosion.
There are many harmful effects of physical change. Some of these things mean that the items no longer fit where the need to.
Useful change is something which fixes something which is broken or out-of-date or makes using something easier and more smooth. Harmful change is something which is made purely because the maker of the change thought it would be helpful, but failed in attempt. Harmful change makes using things harder and is always unnecessary and unwanted. Harmful change changes something which isn't broken, making it worse than it was before.Sometimes it's hard to see beforehand which change will become useful or harmful, so the only choice is to test it, to make the change. People are usually very change-resistant, and that is because everything new creates suspicion before it's accepted. No matter if the change is good or bad, it takes time for people to get used to it. Only time will show if some changes were useful or harmful. Although it's generally recommendable to make change once in a while, because stucking in the past is not improving, but if everything works very well, the change may not be needed.
