In global world there are so many people and everyone does not reuse waste materials like plastic and paper. Majority of them can not know about harm of wasting ecology or sorting trash for them can be hard; to solve this issue people can inprove waste managament systems and reuse materials.
One of the main cause of not recycling trashes is unawareness about consequences of wasting environment. Most of people and farmers use only once plastic bottles, bags and throw them into the urns or to outside. It definately damage the wildlife animals and plants. For example, there are trash island in Pacific Ocean and fishes, dolphins, turtles that lives in ocean can eat these plactic materials and die. If one type of animals extinct, it will hurt to other types of animals that eats them, so it leads to ruining ecosystem. To prevent this situantions people should reuse materials like palstic bags or start using reusable bottles to solve spending plastic. When people do not know about recycling it is can be dangerous for all population on Earth and everyone should try to safe the world.
Another reason why society do not recycle waste materials is difficulty of sorting them. For some people it is not easy to sort trashes immadiately because they can think that sorting is not important or they can sort later when they throw it. For instance, in the ruins of life some people forget about sorting and it is simple to smash it in one urn. They can know about consequences of wasting but their habits stronger than understanding. To solve this issue schools, univesities, everyone should learn about wasting management to protect ourselves and others. One issue can make another issue like not recycling waste materials can lead to air and water pollutions, so people must do right things to develop the planet.
Wasting nature is harmful for everyone and everything. Awareness about recycling and reusing can be better for society. People should do everything to protect global world. If people solve this problem, most of problems can disappear.
