Knowledge-Environment

Environment?

What is it? An environment is everything around us. We have our own individual environment. We all depend on our environment, which is why it has its influences on us. What does the environment consist of? Everyone has their own environment, so it can vary from person to person. But, let’s forget these environments for now. Think of the Earth’s environment. It has changed a lot. There are several problems about the environment of the Earth. In today’s world that environment has become a big problem. One of the biggest problems is pollution of several kinds; including air pollution, water pollution etc. Air pollution occurs when harmful gases are released into the air. Why do we produce these gases, if we know that they are harmful? It is because it is very expensive to not to pollute and yet produce the things that are required. For example, when we make electricity, we burn fossil fuels to provide energy to be converted, but it is very expensive to produce electricity in that much quantity with renewable sources like air.


Secondly, there is water pollution which kills fish that we could have eaten, then why do we pollute water? When we use nuclear energy to produce electricity, there is radioactive waste. It is dangerous to keep in the factory, so it has to be disposed off somewhere, like a lake. But the lake has good fish to be eaten, then why pollute it? It is because it is too expensive to dispose off the waste properly. How does this affect the environment? If we stop polluting, everything in the environment will become much better. Land pollution is when we throw rubbish just on ground. This allows harmful chemicals to enter the soil and pollutes it. See these pictures:
