Good and Bad Effects of Chemistry

What is Chemistry?

Chemistry (a creative discipline chiefly concerned with the study of matter: its structure, composition, properties, and reactivity through chemical reactions) is important because everything you do like cooking, fermentation, glass making, and metallurgy is chemistry! Even our Human body is made of chemical elements.

Chemical reactions (an integral part of technology and indeed of life itself that involves a rearrangement of the constituent atoms of the reactants to create one or more different substances ― the products) occur when you breathe, eat, or just sit there burning fuels, smelting iron, making liquid crystals and semiconductors, brewing beer, and making wine and cheese. All matter is made of chemical elements, so the importance of chemistry is that it's the study of everything ― is part of everything in our lives. 

?Good Effects:

• Helps mankind develop food preservatives that are widely used in the food industry to preserve the natural characteristics of food and to fight food spoilage caused by bacteria, molds, fungus, and yeast.
• Helps mankind develop fuels that we use today as dense repositories of energy that are consumed to provide energy services such as heating, transportation and electrical generation.
• Helps mankind enclose the design, development, and synthesis of pharmaceutical drugs that prolong our life and help us fight diseases.
• Helps mankind develop cosmetics that we use today to enhance or alter the appearance of the face or fragrance and texture of the body.
• Helps mankind develop pesticides that are widely used in agriculture for the protection of crops from disease, insects, rodents and regulating plant growth and killing weeds.
• Helps mankind develop fertilizers that enhance the natural fertility of the soil and improve growth and productiveness of crops.
• Helps mankind analyze the non-biological trace evidence that is brought in from crime scenes and reach a conclusion based on tests run on that piece of evidence.
• Helps mankind devise new ways to make the manufacturing of the products (from fireworks to explosions) easier and more cost effective.
• Helps mankind develop safety strategies for handling dangerous materials, and supervise the manufacture of nearly every product (from pharmaceuticals to fuels and computer components) we use.
• Helps mankind to remove valuable metals from an ore and refine the extracted raw metals into a purer form.

Bad effects:

• Accidents or incorrect use of household cleaning products may cause immediate health effects, such as skin or eye irritation or burns, or may influence children's gut bacteria and cause obesity.
• Chemistry is at the heart of environmental issues. Chemical pesticides are known to pollute the environment as they can work their way into the food chain and accumulate or persist in the environment for many years.
• Maleic Hydrazide is generally added to potatoes to keep them from sprouting. It is a known chemical inhibitor and can even lead to cancer in the long run.
• Plastic cannot biodegrade. Toxic chemicals leach out of plastic water bottles, bags and straws make their way into our bodies and cause a variety of health issues that result cancer, reproductive issues, immune system suppression and problems with childhood development.
• Chemicals that are widely used in cosmetics and personal care products can cause changes in women's reproductive hormones and harm women's fertility or even cause breast cancer.
• Chemical waste is a usually a byproduct of a large scale factories and laboratories that ― if improperly managed or disposed of ― may pose substantial hazards to human health and the environment.
• The excessive use of fertilizers can destroy soil nutrients like sodium, potassium, nitrogen and creates imbalances in soil fertility and result in failure of crops in agriculture and can pollute groundwater.
