Plastics pose a threat to the environment because the breakdown of different types of plastic leads to the release of various toxic chemicals. Plastic debris prior to decomposition also poses a variety of risks to wildlife and ecosystems.Know More
Chemist Katsuhiko Saido of Nihon University in Japan led a team of researchers to discover that plastic breaks down quickly in the ocean, releasing chemicals such as bisphenol A, or BPA, and styrene trimer. Styrene trimer is potentially carcinogenic, while BPA interferes with animal endocrine systems, disrupting reproductive function. This same breakdown may also occur in landfills where chemicals potentially leech into groundwater supplies. According to the Centers for Disease Control and Prevention, 93 percent of people exhibit discernible levels of bisphenol A in urine. In the world's waterways, these toxins extend beyond the water's surface. Many of these toxic molecules are heavier than water, meaning they slowly sink and disperse throughout the water column. Warm, tropical waters are more susceptible to this breakdown, as breakdown occurs more quickly in warmer temperatures.
Aside from chemical byproducts, intact plastics pose an environmental threat. Many animals accidentally ingest plastic products, sometimes with fatal results. Plastic bags and soda rings also entangle unlucky wildlife, sometimes preventing the mouth from opening or causing suffocation. Invasive species may also hitch rides on floating plastic debris in water.Learn more about Human Impact
Some of the major disadvantages of multinational companies include the use of slave labor, may push local businesses out of the market, encourage too much expenditure on consumers, may pose a threat to the environment and may become a monopoly. These companies have the financial and resource power to achieve certain things within a short time which is why they also have these disadvantages.Full Answer >
Plastic poses several environmental risks, including leaching chemicals and toxins into surrounding ecosystems, threatening the health of local animal populations and releasing greenhouse gases into the air. The negative effects of plastic vary depending on the type of plastic in the environment, quantity and length of exposure time. Plastics contain compounds, such as PVC and BPA, elements deemed a health risk to humans and animals while the leaching of these compounds into air and waterways poses a health and safety risk for nearby organisms.Full Answer >
Poaching has a considerable negative effect on the environment because when one animal population declines at an unnatural rate, others can rise or fall as well. This may lead to the extinction of the poached animal and other animal and plant life in the area.Full Answer >
The purpose of recycling is to conserve energy, help the environment, reduce pollution, slow global warming and reduce waste products in landfills. By recycling, people can greatly contribute to the earth’s overall health and keep the air, water and land clean. Recycling is a simple and easy way to help save the environment.Full Answer >
