recycling of plastics bringing any long-term benefits to the environment? Plastics are one of the most popular building materials of modern human culture‚ but its widespread has brought many problems and caused environmental issues of extraordinary scale. Throughout the years‚ discarded plastics are accumulating as debris in landfills and in natural habitats worldwide. To control this issue‚ governments of many countries have established industrial processes for transforming discarded plastic into useful

Plastic in Our Oceans 46‚000 pieces of plastic per square mile make up 90% of our ocean’s trash accumulation (Nichol‚ 2012‚ Plastics‚ like Diamonds‚ are forever‚ para. 1). Within the areas‚ many animals will either ingest‚ become entangled in‚ or even die due to the high plastic amounts. Nearly 267 species are harmed by plastic (Nichol‚ 2012‚ Fast Facts). With such deadly effects due to yearly accumulation‚ the banning of plastic bags and reduction of usage in a household will improve overall health

Research Investigation Safety features in cars Air Bags Air bags are safety features installed in cars so that upon collision the driver limits the damage that is inflicted on him/her. There are several different types of air bags. These include‚ Supplementary Restraint System (SRS)‚ an Air Cushion Restraint System (ACRS) and the Supplemental Inflatable Restraint (SIR). Air bags are commonly known for their rapid inflation upon a collision. They can inflate and deflate within 0.05 seconds

Plastics are synthetic substances produced by chemical reactions. Almost all plastics are made from petroleum‚ except a few experimental resins derived from corn and other organic substances. "Plastics" derived their name from their properties to be molded‚ cast‚ extruded or processed into a variety of forms‚ including solid objects‚ films and filaments. These properties arise from their molecular structure. Plastics are polymers‚ very long chain molecules that consist of subunits (monomers) linked

most households poly bags are used to preserve food items. Reused bag may be contaminated by materials harmful to human health. Environmental preservation and conservation have been fads these days. The hard work of nature advocates has seemingly achieved success and a product of this is the campaign to ban the use of plastic bags in many places worldwide. Plastic bags‚ as noted by environmentalists‚ are among the main causes of nature degradation. Current plastic bag use and disposal‚ both
