Passage1
Plastic waste is a significant environmental issue that demands our attention. There are several ways in which plastic waste is disposed of, each with its own implications.
(1)____ This is the most common method of disposal. Landfills are filled with tons of plastic waste every day. As the plastic sits there, it undergoes various processes.
When plastic waste is exposed to rainwater in landfills, it can create leachate. (2)____ This harmful liquid can seep into the soil and groundwater, causing long - term pollution.
Some plastic waste makes its way into water bodies. (3)____ From small streams to large rivers, and eventually to the ocean, plastic travels long distances.
Once in the ocean, plastic waste can form large garbage patches. (4)____ These patches are not only an eyesore but also a major threat to marine life.
(5)____ Recycling plastic waste can help reduce the amount of plastic that ends up in landfills or the ocean. It involves collecting, processing, and reusing plastic to make new products.
A. The process of plastic reaching the ocean is a gradual one.
B. One of the most concerning destinations is landfills.
C. Recycling is a more sustainable solution to plastic waste.
D. Leachate is a mixture of water and toxic substances from the waste.
