Why are natural resources depletion day by day?Give two reasons.
Answers
Answer:
This is because of-
Exploitation of minerals by humans inefficiently over hundreds of years.
As they take a long time to form back, they are considered non renewable and are misused.
Explanation:
Answer:
The depletion of natural resources occurs when resources are consumed at a faster rate than that of replacement. Natural resources are those resources that are in existence without human actions and they can either be renewable or non-renewable. And when it gets down to the discussion of natural resource depletion, it a terminology used in reference to water usage, farming, fossil fuel consumption, fishing, and mining. And above all, natural resource depletion is defined on the premise that the value of a resource is measured in terms of its availability in nature.
A resource that is rare on earth due to depletion has a higher value than a natural resource which is in abundance. Due to the increasing global population, the levels of natural resource degradation is also increasing. Consequently, the world’s eco-footprint is estimated to be one and a half times the ability of the earth to sustainably provide each individual with enough resources that meet their consumption levels.
Causes of Depletion of Natural Resources
1. Overpopulation
The total global population is more than seven billion people. Still, there is a consistent increase in the overall earth populace and this has been a critical factor in accelerating the depletion of natural resources. An increase in the populace expands the need for resources and conditions necessary to sustain it.
In addition, it contributes to increased ecological contamination. Research further indicates that developing countries are using more and more resources to industrialize and support their ever-increasing population. Hence, the depletion of natural resources will continue as long as the world population increases.
2. Poor Farming Practices
Humans are causing a lot of stress to land resources due to the over-reliance on food production for daily nutritional requirements. Poor irrigation practices, for example, is a key contributing factor to salinization and alkalization of the soil that sustains plant growth. Poor soil management practices and the use of heavy machinery and farming equipment also destroy the soil structure making it unsuitable for plant growth.
Some farming practices such as excessive use of pesticides, fungicides, and herbicides equally kill important soil micro-organisms that are essential in replenishing nutrients in the soil.
3. Logging
The World Bank reported that the net loss of global forest between 1990 and 2016 was 1.3 million square kilometres. On the same note, tropical deforestation is estimated to occur at a rate of one per cent annually, especially in Latin America regions. People are clearing forests primarily for agricultural reasons due to the increase in the population pressure.
