Why are humans concerned about chemicals in the environment?
Chemicals can be of concern because of their pervasiveness, potential to accumulate, possibilities of interaction, and often long-term unknown effects on people and the environment (e.g., cancer, mercury in fish).
How does releasing chemicals into the atmosphere affect climate change?
Heat-trapping gases like carbon dioxide (CO2) absorb this infrared radiation and prevent it from dissipating into space, giving rise to what we know as the greenhouse effect. The accumulation of CO2 and other greenhouse gases in the atmosphere is the dominating driver of recent climate change.
Is releasing chemical into the environment?

What are the harmful effects of chemical pesticides?
Examples of acute health effects include stinging eyes, rashes, blisters, blindness, nausea, dizziness, diarrhea and death . Examples of known chronic effects are cancers, birth defects, reproductive harm, immunotoxicity, neurological and developmental toxicity, and disruption of the endocrine system.
How do chemicals affect agriculture?
EFFECTS OF AGRICULTURAL CHEMICALS IN SOIL
The main difference from cultivation is that the effects of chemicals lasts longer . Whereas ploughing or rotation may only change the balance of the soil fauna or flora for a matter of weeks or at most months, persistent chemicals can alter them for months or years”.
What is chemical pollution in the ocean?
