选项
答案 What Should Human Do to Preserve the Nature? In the past few centuries, humans have had an especially negative effect on Earth’s natural environment. It is essential to realize that as rational beings, humans have the ability to not only understand the problems we have created and what needs to be done to amend them, but also the capability of accomplishing these tasks. One of the major threats to our environment is the amount of waste we produce. There are many things that we can do to reduce waste. We can put three separate recycling bins in classrooms, offices and in the kitchen. One bin is for paper, another for organic waste, and the third is for cans and bottles. We should think about whether we need all the paper you use. We also can print or copy on both sides of the sheet. What’s more, we should protect our wetlands and waterways. They provide habitat for wildlife, they can be breeding grounds for fish, and the source of life for entire communities-including humans. Let’s install water conservation devices in the home, school and workplace. Triple a shower heads, flow re-strictors on taps, and dual flush toilets can more than halve the amount of water we use, which will save our money too. Don’t use soaps or detergents in the river when camping, as this can upset the aquatic e-cosystem. In addition, the greenhouse effect and ozone depletion are global issues, but there are lots of things we can do to help solve these problems at the source. We can choose an energy-efficient appliances and a fuel-efficient vehicle. The best way is to choose a home close to work, then we can go to work on foot or by bike. To save our earth, we can take some measures to protect environment. If everyone makes contribution to protecting the environment, the world will become much more beautiful.
