Different Types of Environmental Pollution

Thursday, January 13th, 2011

People always think that the water and air on the earth is endless, so they keep emitting million tons of waste gases into the sky and dumping numerous garbage into the rivers, lakes and oceans. As a result, human activities cause different types of environmental pollution. The clean-up of the garbage has become an important issue in many big cities. Among the million tons of garbage every day, most can not be incinerated or decayed, such as plastics, rubber and glass, which are considered as the number one enemy of mankind.
Marine pollution is mainly caused by the crude oil leaked from oil tanker and oil well, the pesticides and fertilizers used in agriculture, the sewage discharged from factories, and the acid solution exhausted from oil field. These wastes make most of the oceans and lakes polluted. As a result, not only the marine organisms are affected, but both the birds and humans may also be poisoned because of eating these organisms. Air pollution is the most direct and serious environmental pollution, mainly from the carbon monoxide and hydrogen sulfide emitted from factories, cars, power plants, and so on. Every day, there are many people infected with respiratory organ or visual organ diseases due to the exposure to these polluted air.

Water pollution happens when certain substance enters into the water and changes the chemical, physical, biological characteristics of the water, which then affects the efficient use of water, endangers human health, causes harm on the environment, and leads to the deterioration of water quality. Air pollution means that the concentration of pollutants in the air reaches to or above the hazardous level, which leads to the damage to ecosystems and the normal survival and development of human life. As a result, it will bring harms both on human being and creatures. Noise pollution is the phenomenon when the environmental noise exceeds the national emission standards of environmental noise, and interferences with the normal work, study, and living of other people.

Natural Disaster Survival Kits

Saturday, October 23rd, 2010

Disaster can strike at any time and it can happen because of an act of nature, or by an accident, or even by a deliberate act of man. Being prepared for any disaster can be difficult, but it can also mean the difference between health and injury, minor injury or major injury, or even life or death. Being prepared is critical, and that also means having the best equipment around to deal with a sudden emergency situation. Whether the disaster is urban based, or from terrible weather, a good natural disaster survival kit can help individuals to survive through the worst situations. There are two ways to go when putting together a disaster preparedness kit. One is to simply buy a kit that has already been put together by professionals. Buying an already assembled survival kit is the most normal way of going, but then the problem is that many people never bother to open the kit and familiarize themselves with the tools or materials that are inside – which defeats the entire purpose of having a kit to help prepare you for an emergency.

The other option is to put together your own homemade disaster kit. By gathering the materials yourself, you will already know how to use the resources in your kit. Even better, you can make sure that every possible contingency you can imagine from a natural disaster is covered by the materials you know will be in your kit. When preparing for any type of a natural disaster or survival situation, this is not a bad way to go. And if you’re still concerned about putting together a quality disaster survival kit, then you may want to do some research and check out some of the many online resources that can help guide you in putting together a package that will really help you out when disaster strikes.
