Hello to all the mentors,ambassadors and members, In today’s world, it is impossible to imagine a world without man made chemicals. If we look around us, the volume and amount of chemicals present around us is astonishing. For example, there are so many chemicals present in the food we eat,cosmetics, cleaning products, clothing and toys.Today I will be telling you about a few chemicals that affect the environment negatively. Pesticides and Insecticides : Pesticides are substances that are meant to control pests, including weeds.The term pesticides usually includes fungicides , herbicides and insecticides. Although pesticides prevent pests and other insects from ruining the crops, these have a major impact on the ecosystem as well as human health. Firstly, these pesticides contribute to air pollution. Due to wind, the particles of pesticides get suspended in the air. These particles could potentially harm human beings. In a research conducted by the US Geological Survey, it was found that pesticides pollute 90% of wells. This is alarming, as it can impact the ground water level. Thirdly, these pesticides kill useful microorganisms. Alternatives to pesticides: Biopesticides are certain types of pesticides derived from such natural materials as animals, plants, bacteria, and certain minerals. For example, canola oil and baking soda have pesticidal applications and are considered biopesticides. Since these pecticides are made from natural materials, they will affect the environment less. Also, Biopesticides often are effective in very small quantities and often decompose quickly, resulting in lower exposures and largely avoiding the pollution problems caused by conventional pesticides. EDCs (Endocrine Disrupting Chemicals) : These are chemicals that interfere with naturally produced hormones ( our body’s chemical messengers). Out of these, some chemicals mimic hormones by sending false messages. Some others prevent true messages to get through. EDCs acummalate in the tissues of organisms and move up through the food web. Since these chemicals pass from mother to off spring , they harm species far from their original source. Some common examples of EDCs include DDT and other pesticides; bisphenol A (BPA) and phthalates used in children's products, personal care products and food contain- ers; and flame retardants used in furniture and floor coverings.

Hi Arjun Anand, this is a mentor, Sang Su Lee.
Thank you for your report about pesticides and their impacts on the environment. Bio-magnification and resistance within pests due to pesticides are two most serious problems that the environment is facing due to pesticides. Always we have to use proper amount of them, or we can use bio-pesticides as you mentioned.
Green Cheers@!

Hello Arjun Anand, this is mentor Taehyun!
Thank you for the report about pesticides. Pesticides are for the convenience of the farmers. And ultimately, it is a chemical product that is designed to kill living things. So, is it safe to the human? I cannot answer it easily so like you. We have seen many examples of chemical exploitation and all of that ended tragically. So, let's consider the chemical properties which can be related to environmental pollution!
Thank you for the report!
Green cheers!
