Half of the planet’s population lives in cities, yet they consume 75% of the world’s resources and create most of their pollution. This means that all governments are going to have to create effective recycling plans. In cities where recycling schemes have been successful, it is possible to recycle 95% of all household waste. It takes 30 – 40% less energy to make paper from recycled materials than it does to make it from trees. Statistics show that there is a growing awareness of the importance of recycling, and countries such as Sweden already recycle much of their waste.

As the burning of fossil fuel is a major cause of pollution we will have to turn to other energy sources and what could be a better source than the sun? Solar energy is getting cheaper and can produce power even in cloudy conditions. The Japanese have already developed solar-electric roof tiles which are going to make entire buildings self-sufficient, greatly cutting down the need for fossil fuel.

What is the advantage of recycled paper?

Dear Kate,

How have you been? It has been a long time since I wrote a letter. I was caught up with the holidays and Mama's family came over, so was not able to write any. Hope you have become accustomed to the hostel food there.

When Mama and her family came over, we all went to the Jim Corbett National Park. It was spread on a huge area with huge deciduous and mango trees. There were more than 100 species of trees, with so many varieties of birds, reptiles, and other mammals. The Tigers were the special tourist attractions there.

We also went on an early morning safari and we were able to spot a sambar deer and an elephant. There were the Kalagarh dam and the Corbett falls which were awesome. I will show you all the pictures when you come over for the next holidays.

Also, let's plan to visit there together again when you come here.

Study well, eat well, and sleep well.

Take care.

Love,

Jack

The research of alternative resources of energy has resulted in various directions. Many communities are burning garbage and other biological waste products to produce electricity. Changing waste products into gases or oil is also an efficient way to dispose of waste. Experimental work is being done to make synthetic fuels from coal, or coal tars. But today, that process has proved expensive. Giant windmills have been built to provide a considerable source of electricity. Other experiments in geothermal power are being tested to harness power deep inside the earth.

Some experts are trying to revive hydroelectric power which is derived from streams and rivers. Fifty years ago, hydroelectric power provided one-third of the electricity used in the United States, but today it supplies only four percent. The oceans are another source of energy. Scientists are studying ways to change the energy of ocean currents, tides, and waves into electricity. Experiments are also underway to make use of temperature differences in ocean water to produce energy.

According to the writer, synthetic fuels from coals or coal tars are _____
