【正文】 its cities, chemical spills are fouling its rivers and drinking water supplies, soil contamination is undermining its agriculture, and raw sewage is causing widespread disease. This environmental toll has led to internal riots, international protests, and the arrest and trial of a leading Chinese environmentalist. In 2021, China pledged to invest $175 billion by 2021 to control water pollution, improve air quality, increase solid waste disposal and reduce soil erosion — investments intended to pay economic as well as environmental dividends. A sample of Ex 4 on page 7 Responsible Choices The choices we make and the products we buy test our mitment to maintain a healthy pla. When we burn fossil fuels such as oil, coal, and natural gas to run our cars and light our homes, we pump carbon dioxide (CO2) into the air. This thickens the heattrapping blanket that surrounds the pla, causing global warming. Choosing modern technology can reduce our use of fossil fuels and help protect the pla. These steps will help curb global warming, save you money, and create a safer environment for the future. Drive Smart! A welltuned car with properly inflated tires burns less gasoline cutting pollution and saving you money at the pump. If you have two cars, drive the one with better gas mileage whenever possible. Better yet, skip the drive and take public transit, walk, or bicycle when you can. Replace incandescent light bulbs with pact fluorescents bulbs. Especially those burn the longest each day. Compact fluorescents produce the same amount of light as normal bulbs, but use about a quarter of the electricity and last ten times as long. Each switch you make helps clean the air today, curb global warming, and save you money on your electricity bill. Bee a smart water consumer. Protecting forests is a big step on the road to curbing global warming. Trees breathe in carbon dioxide, but slashandburn farming practices, intensive livestock production, and logging have destroyed 90 percent of the native forests in the United States. And you can take action in your own backyard — planting shade trees around your house will absorb CO2, and slash your summer airconditioning bills. Reduce! Reuse! Recycle! Producing new paper, glass, and metal products from recycled materials saves 70 to 90 percent of the energy and pollution, including CO2 that would result if the product came from virgin materials. Recycling a stack of newspapers only 4 feet high will save a goodsized tree. Please...buy recycled products! Mount a local campaign against global warming. Educate your munity about how it can cut global warming pollution. Support measures at the national, state, and local level that: ? Make automobiles go further on a gallon of gas。 ? Accelerate the use of clean, renewable energy sources, such as solar and wind。 ? Increase energy efficiency and conservation。 ? Preserve forests around the world.
