What is the most serious environmental problem facing Earth today?

I believe the most serious problem Earth is facing today is definitely air pollution. This may not seem right because not anywhere people can actually see air pollution. The main source of air pollution is caused by the humans. Wether it is by combustion of fuels or the use of radiactive material, humans are to blame for this serious problem. The other factor that cause this issue is deforestation, which is why the main pollutant, carbon dioxide, spreads through the world. The whole excess of carbon dioxide thing is actually caused by the overpopulated human race. This problem can be solved, but the acceptance of the fact that the people have to stop reproducing that much is going to take some time. The habit of reproducing is in our very nature, but the excess of a habit becomes an addiction, a deadly one.

The main reason for overpopulation has been our extremely sedentary lifestyle. To this also adds the fact that medicine and sciene is able to raise our lifespan expectancy. So, in a way our own technology is killing us. However, we can't stop using medicine because it is immoral and it will only cause harm. Basically we have got to the point in which reducing the population is almost impossible. We as humans don't think its normal yet to use birth control methods, sure some people do but not most of the people do. From the beginning of time, humans have grown the habit of hunting and living together, this habit has been changed in the way in which we take much more than needed. There is also the big fact that we simply waste resources, straight forward throwing away near-new products.

As simple biology states, we humans breathe oxygen and exhale carbon dioxide. The normal person would think that the amount produced its nothing. But only if you could multiply that quantity for 6 billion in a constant rate, the amount is immense. Also, one person would think that trees would simply use it, even considering it a favor towards the trees, wrong. Trees are disappearing and it is destroying affecting us directly, and so thats why we can see the effects of air pollution in most big cities, there are no trees in those places. Trees and plants in general are what makes other life possible on the planet, they keep the environment in balance. We need to perform sustainable activities.

So, this far reducing pollution seems straight forward morally wrong. If we are willing to keep the human race alive for more time, we have to learn to coexist with the many other organisms on the planet. Over time, we have settled on the planet as if we are the only organisms that inhabit the planet. You can easily see the effects of overpopulation, wars, starvation, massacres. It is all due for the constant need of resources and if we don't want violence we have to learn to take advantage of every last part of resources. Humans are now starting to understand the value of their resources, because they're running out. We are now starting to recycle and make a smarter use of what we have.

In conclusion, we can still keep evolving in the science and with medicine but we also need to make big changes in our way of life. We need to start to stop depending solely on technology, we have survived before and we shall do it again if we really try hard. We can take much advantage of technology but up until the moment technology doesn't damage so harshly the planet. We should use the great advances in technology we have and start making changes, like birth control and just with this we will be able to see big changes in the world. If you're not selfish and you want the other generations of humans to deal with our troubles you shall help and you shall care more about the organism that gives the most, the Earth.
