The brief introduction of myself

When referring to this topic, what do you think of?

Maybe you sign that we are facing so many environmental problems? Yes, absolutely right. But how much do you know about that? And there is a serious issue that it’s never enough just to know that, but why, why we have such problems and how should we do to protect our living garden, the earth?

How much do you know about the environmental problems?

Top 10 Environmental Problems

Acid Rain

（酸雨）

Acid rain is caused by pollution released from factories and other

manufacturing processes as well as many other pollutants. It can create acidification of lakes and cause damage to plants and wildlife. It also increases the rate of decay of buildings and other man-made items.

Air Pollution

Learn about the causes and effects of air pollution and a little about air pollution throughout history. Learn about some of the solutions to reducing pollution in our air, such as energy conservation techniques, using renewable sources of energy and improving overall energy efficiency in many different products. You may also want to read about improving indoor air quality.

Chemical Waste（化学废料）

When manufacturers release chemicals into the environment instead of disposing of them properly, it can cause any number of environmental health hazards. Although the Environmental Protection Agency monitors companies, sometimes mistakes happen or accidental spills occur. It is probably rare for intentional waste to be spilled, but that happens as well. You can also read about Environmental Hazardous Waste.

Contamination of Marine Habitats（海洋生物污染）

Pollution of marine habitats can occur in any number of ways, including oil spills, trash dumped into the oceans and other chemical spills. Although debris is a big hazard to creatures of the sea, chemicals and other things dumped into waterways make their way to our oceans and cause even more trouble. Many animals have been saved from these dangerous habitats, but pollution continues to be a problem.

Deforestation

Although deforestation at first glance may not seem to be a big issue, the environmental impact can be huge. Many lumber companies have begun to replant trees in recent years to help stop the spread of this problem. However, the effects of deforestation can include soil erosion, changes in the water cycle, floods, droughts and is suspected to play a part in climate changes.

Diseases

Many of the growing problems with diseases is thought to be related to pollution and environmental problems. Experts suspect that increased exposure to chemicals may cause breast cancer, severe allergies and increase the risk of heart disease and stroke. Studies such as those conducted by the Environmental Working Group (EWG) show that changes must be made.

Extinction of Species（品种灭绝）

Many of the other environmental problems listed seem to be contributing to mass species extinction. In addition to species that have already gone extinct, there are many species in danger such as Siberian Tigers and the Arakan Forest Turtle. Learn more about how population growth is contributing to species extinction. Go to the news portal for regularly updated reports on species in danger.

Global Climate Change One of the utmost environmental problems facing our planet today is global climate change. Learn more about the basics of climate change, such as shifting weather patterns, melting polar icecaps and greenhouse warming. Learn more about what can be done about climate change. You'll even find some lesson plans and learning modules to help students learn more about this important

topic.

Overpopulation

Human overpopulation is causing many of the environmental problems we face today. More humans means more energy

consumed, more trash produced and more areas developed. Learn

more about the effects of overpopulation and what can be done to

try to reverse the damage. You'll also find out what species are

being most impacted by results of overpopulation.

Water Quality One impact of environmental pollutants, wastes and chemical spills is an overall reduction in the quality of water. Learn more about what water quality means and learn about ways to tell if your

drinking water is safe. The USGS also offers material for schools to help children learn about water quality and how it can impact their lives and the community around them.
