what are consequences of over exploitation of resource
Answers
There are two types of natural resources: renewable and non-renewable. The former are inexhaustible, like solar radiation, or their renewal is relatively rapid, as is the case with biomass. Non-renewable resources are those that exist in nature in a limited way because their regeneration involves the passage of many years, such as minerals and fossil fuels (oil, natural gas and coal).
Human beings are depleting the planet's natural resources and standards of living will begin to decline by 2030 unless immediate action is taken. The World Wide Fund for Nature (WWF) warns that the current overexploitation of natural resources is generating an enormous deficit, as 20% more than can be regenerated is consumed each year and this percentage is growing steadily.
Thus, if we continue at this rate, we would need 2.5 planets to supply ourselves in 2050, according to the latest Living Planet report (2016). This publication shows that the world's population of fish, birds, mammals, amphibians and reptiles declined by 58% between 1970 and 2012 due to human activities and predicts that by 2020 this percentage will soar to 67%.
Overexploitation or overfishing is the removal of marine living resources to levels that can not sustain viable populations. Ultimately, overexploitation can lead to resource depletion and put a number of threatened and endangered species at risk for extinction.
