Most Dangerous Human Activities that affect the Environment

Many believe human activities are the only reason behind climate change. Ecosystems are the basis of a healthy environment. But population explosion forces them to attack the habitats, producing wastes which result in an unfavourable environment, that is what we called as Climate change. my aim is not to blame humanity, but it’s a reality. So we have to realise it, we should open our eyes. Here we are going to discuss some of the Human Activities that affect the Environment.

Deforestation in Increased Rate

Deforestation is the permanent destruction of the forest cover in order to make the land available for other uses. An estimated 7.3 billion hectares of forest, which is roughly the size of  the country of Panama, are lost each year, according to the United Nations Food and Agricultural Organization (FAO).  World Wildlife Fund says, about 36 football field worth of trees lost every minute, and if current deforestation level proceed, the world’s rain forests may be completely destroyed in as little as 100 years, Predicts NASA. The Population explosion is the main reason behind high rate deforestation.

Extreme level of carbon emission

Carbon dioxide is the primary greenhouse gas emitted through human activities. Carbon dioxide is naturally present in the atmosphere as part of the Earth’s carbon cycle. Human activities are altering the carbon cycle both by adding more CO2 to the atmosphere and by influencing the ability of natural sinks, like forests, to remove CO2 from the atmosphere. We are largely relying on petroleum-based fuels to satisfy world’s Energy needs. Renewable sources of energy have been gaining more and more attention. But we prefer fossil fuels because of high energy density and efficiency. The main human activity that emits CO2 is the combustion of fossil fuels such as Coal, Natural gas and Oil for energy and transportation.

Over-exploitation of Minerals and Resources

Over-exploitation of minerals resources has resulted in many environmental problems. Mining and extraction process are one of the sources of air, water, and land pollution. In the entire history of human civilization, such an unusually high demand  has never been placed in natural resources of our planet. The consequences of this over-exploitation  of natural resources and minerals wealth have to be serious, drastic and enormously damaging to the entire biosphere.

Uncontrolled Mining of Sand from rivers, black stone, red stone

Surface mining results in the complete destruction of  upper soil layer and vegetation. Surface mining directly degrades the fertile soil surface thus affect the ecology and climate of that area. In India, we can see several stone mining quarries that mine black or red stone from hills, especially in the Western Ghats. People are mining stones for construction works such as houses, Airport, apartments etc.  Some of the beautiful hills have already disappeared from western ghats. I am really concerned about it. I believe hills are the veins of  groundwater reservoirs. And people are not leaving any rivers without mining sand from it. Over-exploitation of sand from rivers will soon kill them.

Hill leveling for mining, industries, road transport 

Some of the hills in Kerala In India is facing extinction. Yes, it’s the right time to protect our western ghats. Western ghats are the only reason behind the beautiful climate in Kerala. There are several studies suggesting strict rules to protect western ghats, but our government is not paying attention. Hill leveling would affect ground water level and  destruction of habitats. Hills play an important role in natural rainwater harvesting. The forest cover help hills to collect and fix the rainwater into the ground water reservoirs without allowing it to flow directly to the sea.

Wet-land Disappearance

Conversion of wetlands for commercial development, drainage schemes, extraction of minerals and peat, overfishing, tourism, siltation, pesticide discharges from intensive agriculture, toxic pollutants from industrial wastes and the construction of dams and dikes, often in an attempt at flood protection are major threats to wetland everywhere. Nearly half of the world’s wetlands have disappeared since 1900. Wetlands are the natural resources of water which can store a large quantity of rain water and allow it to slowly absorbed by the Earth. Development and conversion continue to pose major threats to wetland, despite their value and importance.

Other Human Activities that affect the Environment

  • Unsafe disposal of plastic wastes
  • Groundwater exploitation for industrial purposes
  • Pollutions such as water pollution, Air pollution, soil pollution, sound pollution etc
  • Different types of wastes such as Plastic wastes, Concrete wastes, Chemical Wates, Electronic wastes etc
  • Unsafe use of agricultural and Industrial chemicals
