SAMPLE WRITING
One of the biggest problems facing humans nowadays is global warming. The Earth is heating up: warmer temperatures are causing changes in climate around the world. Human demand for natural resources has increased rapidly, especially in developing countries. Human activities have led to the pollution of the environment, threatening living conditions for millions of species, including people themselves. If we do not take actions to reduce the risks now, the impacts of global warming on us will become more and more severe. The essay will discuss the problem of global warnning, its causes and effects and suggest some solutions for it.
Global warming is the rise in the average temperature of the earth due to the increase of greenhouse gases like carbon dioxide, carbon monoxide, methane and others in the atmosphere. People pollute the environment by burning fossil fuels; cutting down trees for farmland, wood and paper; increasing the use of chemical fertilizers on croplands... Human activities have serious consequences on the life on Earth. We have so far witnessed more severe storms, heat waves, droughts, floods and hight tides. Under extreme weather conditions, people have to suffer heat-related illnesses and infectious diseases.
Global warming is seriously affecting our life on Earth in many ways, so everyone of us should do something to reduce it. Begin at home by reducing energy use: unplug all electronic devices when they are not use, avoid lighting at day time, use solar energy instead; saving clean water; planting trees or growing our own foods. Walking and biking to work are green methods of transport, good for health.
In conclusion, global warming is throating human beings and millions of species Earth. The Earth is the common home for all of us and because of this great attent should be paid to environmental problems. Taking small but effective actions such reducing energy use, saving natural resources, planting trees or using green means L transportation can make the Earth a better place to live.
