Oceans cover three quarters of the earth’s surface, contain 97 % of the earth’s water. Over three billion people depend on marine and coastal biodiversity for their livelihoods. Unfortunately, no ocean on earth is unaffected by plastic pollution. The common problem caused by plastic pollution in the ocean which is many marine organisms can’t distinguish the plastic items from food. Animals who eat plastic often starve because they can’t digest the plastic and it fills their stomachs, preventing them from eating real food. According to several kinds of research, 44 % of seabirds, 43% of ocean mammals and 86% of sea turtles are ingest the plastic material. The United Nations Environment Program estimates there could be as many as 51 trillion microplastic particles in the oceans already. Plastic waste in the oceans comes from land, predominantly as a result of mismanaged waste disposal. The initial effort to reduce plastic pollution in the ocean should be focus on preve...

Procedure Text

  This diagram is shows the process of production and recycling glass. Overall, the producing process consists of   4 stages, beginning with the mixing of materials and ending up with glass containers. The recycling process consists of 5 stages, beginning with the collection of a used glass and ending up with the molding into new products. The first stage is glass production. First of all, the raw material such as sand, soda ash, limestone, and other chemicals are mixed. Then, the raw material is melted in a glass furnace with the temperature approximately 1500 ° C. The melted raw material is then shaped by molten glass blowing technique. Next, the shaped glass is put into a glass container. The second stage is glass recycling, first of all is the collection of used glass. Then, the used glass is sorted by the color. After that,   the used glass are washed to remove impurities. Next, the product are crushed and melted. The last step, the glass is m...
