Describe two different ways humans modify the environment, include why they modify the environment and the negative impact of the modification

1) compost: instead of just throwing everything in a trash bag and putting it underground we can use a compost pile to recycle the decayable food, including wood, banana peels, ect.

2) Gasses: when we light candles the scent produces a carbon dixoide to help us breathe. When we breathe in oxygen we release carbon dixoide into the air and when the trees enhale the carbon dixoide in, it will release oxygen. So just that one candle can help save our plaet only by it releasing carbon dixoide.

But when these two examples are not used properly it can lead to a really bad natural disaster like forests catching fire. So when we do not use the compost pile or gasses the proper way it will harm our daily lives.
