“For many of us, water simply flows from a faucet, and we think little about it beyond this point of contact. We have lost a sense of respect for the wild river, for the complex workings of a wetland, for the intricate web of life that water supports.” – Sandra Postel
It has been awhile, but I will waste no time in completing the ecology series. Observing the world more and more people are becoming environmental and health conscious. But, it’s not enough to slow down the deterioration of the environment. There has to be a dramatic shift in governments and large cooperation’s policies towards the environment to obtain meaningful result. Also, every individual in the world must play apart in the process of reducing waste and pollutants. The fact is too many nations are wasting resources, while others are in need. Too much material make it to the dumps. And, this result in more raw material extraction from the natural environment. Humans need to acknowledge that our well-being and survival is not independent of the natural environment. Let’s move on to some problem affecting the natural environment such as:
Over fishing- it involves reducing fish stocks to unacceptable levels. It may affect a specific type of fish due to market demand. Once, over fishing occurs it may lead to the permanent displacement of the original stock and result in a different type of fish taking the original stock place. This can have mixed impact on the aquatic ecosystem, whether severe (extinction of species) to even moderate (stock replenish in a few years). But, the outcome is dependent on the type of fish and conditions.
Deforestation- it involves cutting down large area of forest for various reasons; usually agriculture, lumber and fuel. This result in displacement and extinction of some species of animal. Also, plant are impacted in the same manner. Deforestation contributes to climate change. This is because forests help to absorb carbon dioxide from the atmosphere and even store it.
Soil erosion- Soil erosion occur naturally, but can become severe due to human activities such as; mining, logging and improper farming practices. The two main agent of soil erosion are water and wind. The speed of either and how exposed the soil is influence the level of erosion. Soil result in the displacement of nutrient rich top soil that could cause an area to become barren.
Factory emissions- Factory emissions has a broad spectrum effect on the environment. It pollute our air and then it can come back mix in with rainwater to pollute our aquatic and terrestrial ecosystems. Gases emitted by factories includes; Ozone, Sulphur dioxide, carbon dioxide, ammonia and carbon monoxide. Some of those gases contribute to the greenhouse effect (warming of the earth) such as carbon dioxide.
It’s important to note that factors affecting the environment impact the planet biodiversity negatively.
