Drones have always been into a limited field of army and defence but slowly and steadily it has entered the mainstream. Now these smart bots are being used everywhere from conservation to photography, the uses of these drones have widened its horizon. But there are pros and cons attached, let’s take a walkthrough of how the drones have affected the environmental factors, and are this camera robot a threat or it’s just a mere robotic machine flying in the air. Drones and their Uses – Well if we have a strong understanding of how drones are being used, it gets easy to conclude on the pros and cons. The Defence system proved the monitoring abilities of this machine when further this camera bot was used, the spectacular aerial images opened new horizons for its usage. Now photographers and videographers are among the avid buyers of this gadget. The continuous use of aerial photography and monitoring opened gates for new ways of conservation and protection. The wildlife, agriculture and energy projects have started using drones. The more it is being used in different sectors the debate over the pros and cons have begun, so let’s have a look, how are these drones impacting the environment. Agriculture – The farmers have started relying on the robotic vehicles in order to collect information and take actions accordingly. When a drone identifies a type of weed growing in a specific area that area is then sprayed with a pesticide that helps in unnecessary usage of pesticides in the field. Wildlife - Monitoring and keeping a check on the wildlife animals and plants is now an easy business. Now at very cheap costs and with almost no manual task-force wildlife conservation tasks can be taken care of. Energy Plants – Maintaining big machinery, how to check if they are functioning properly, what are the areas that got affected and so forth. But with this little camera vehicle, almost all are problems being solved. Pros Low Cost – If used effectively then this vehicle will be a cheaper option than other alternatives. Accuracy – Unlike the old and traditional ways of surveillance, drones are accurate and require minimal staff. They are quiet and vigilant machines that give an accurate information. Longer Operational Hours – Humans can be saved from continuous long work duties because these flying vehicles will enable to look/spy/watch for longer hours. Life Saving- Spying or keeping an eye becomes an easy affair via losing any life. Aerial mapping & Monitoring – These little vehicles are best for aerial photography and videography, they are ideal and with a 5 kg drone you can easily fly for several hours and get exquisite images. Disaster Relief – In difficult times, drones act as saviours and are perfect for surveillance and providing aid to the affected zones and the people. Wildlife Protection – This little vehicle is able to capture pictures and videos of hard reach areas, which plays a crucial role in conserving the environment. Sustainable Agriculture – UAV’s are now more precision agricultural instruments and are at a quick speed replacing a lot of old school methods. It is now becoming an invaluable tool for farmers. Cons Limited Abilities - Yes, no matter how much we talk about them, some manual actions are always needed to give directions to these gadgets. Easy to operate – The easy operations of the drones are making it an accessible mode, which will be a concern ion near future. Drone Strikes – Drone strikes and munitions are sad to be harmful to public health because of their chemical content. As we look towards the advances of the growing usage of drones and affordable prices we are sure to see more of these flying machines. There are cons but better benefits quick deploy, clear images and with upcoming technological advances, we can see a win-win situation for these UAVs.
Why is organic waste contamination that bad ? 1.6 billion tonnes of food is being wasted every year around the globe. It’s worth approximately 750 billions dollars and doesn’t solve the problem with world hunger or the economical crisis. Despite the loss of financial and food resources, discarded foods have strong negative impact on wildlife as well. Landfills that consist primarily of dumped food supplies are the perfect feeding destination for all kinds of wild animals, especially birds. The relation between organic rubbish and the population of the birds that feed on it is so strong that removing a landfill causes a chain reaction such as reduction in the population of the flying animals or the cause of reproductive diseases. How come food can make animals suffer ? Such study was made in France. A landfill has been deliberately removed and 49% decline in the fertility among the gulls was measured and confirmed by ecologists. Seems like that dump site has been the prime food source for the flying creatures and after the waste removal the animals have either moved to a better location or some have starved to death. Small part of the organic waste thrown away by people is actually fish discards estimated at 6 million tonnes every year. Even though that is not that much compared to 1.6 billion tonnes, more than half of the seabirds rely completely on the leftovers of the fish, produced by the industry and feed entirely on it. In nature, it’s a commonly seen process for an animal to stop hunting when it is being fed by people. That is how some wolves evolved into dogs and then many dog breeds appeared after experimenting with crossbreeding. Birds are not the only animals that are affected by the discarded organic trash Predators like wolves, bears and leopards become significantly more active if their natural habitat becomes affected by pollution with organic waste. The grizzly population has increased 4 times in 2014 compared to 1970s. Even some of the world’s most vicious predators like the leopard prefer to inhabit areas polluted by organic rubbish which they consume, usually that is butchered animal bodies. The leopards also hunt on creatures living nearby the landfills which you have to stay away from. Their common prey is pigs, dogs, goats and rats that also seek for sustenance at the dump sites. Composting help to solve the food waste issues Composting is the perfect way to fight food rubbish contamination as it is not expensive and can be done by anyone who wants to learn how to do it. It is beneficial as it also helps you save some of the family budget which you usually would spend on buying fertilizers for your garden. Compostable things are divided in two main categories based on what they emit - Carbon or Nitrogen. You can compost stuff like: banana peels, dog food, egg shells, flowers, leaves, peanut hulls, weeds, tea bags, vegetable peels etc. Rubbish removal companies are trying to minimize the amount of organic waste being generated in households by giving advice and raising awareness about efficient waste clearance, especially these operating in London.
It's lunch time. You drive your car and go to grocery store for preparing something delicious. You pick chicken and a pre-made salad. Have you noticed that such actions affect environment? How could it be possible? Let me explain. When you go by car, it releases carbon dioxide to the atmosphere. Air gets polluted. The store that you went into, require light which is powered by coal and as you know that coal mining destroy our ecosystem. What about that salad? Its ingredients grown on farm using harmful pesticides and then washed into local streams poisoning the fish and aquatic plants. Water gets polluted. Even chicken transported by trucks that emits poisonous gas. A smallest action of human creates an environmental change. Think of a bigger picture. Humans are completely dependent on mother nature for survival. But, what you give back? Harmful chemicals that pollutes water, carbon monoxide and sulphur dioxide such undesirable gases causing air pollution. We really need to think on this and stop some where. Have you ever wonder which is one of the main reason in determining the nature? Industrial pollution is the main cause. Earlier industries were limited and so they were less harmful to en vironment. But, with growing population several industries evolved on a large scale with massive production. This has depleted certain natural resources damaging the environment permanently. Best example is deforestation which is clearing of forest for sake of production. “ Grow More Trees” is our motto. Do you think we took this seriously? Just to increase production level, what are we doing? Cutting down the trees and cripple the system. Greed can lead to catastrophic accidents and eventually society has to suffer. Mainly primary industries has caused a massive damage to earth especially mining of coal. This has become one of the biggest issue today. Coal, one of the fossil fuel, is mined with an aim of producing electricity. Imagine a day without electricity. I remember a day when the light goes off just for an hour and I was like yelling and calling at electricity office. We really could not live without it. Not even an hour. Now, you might have come to know how coal is important and so its mining as well. But Wait! All good things come with something not acceptable. Have you ever think of how much damage is caused to surface of earth while mining coal? Let me list down all the drastic consequences that comes along with mining of it. 1. Emission of harmful gases deteriorates ambient air quality With an aim to extract coal from underground mines, mining operation is done. Such operation includes drilling, hauling, collection and transportation and this results into emission of harmful gases like methane, sulfur-dioxide, oxides of nitrogen and carbon monoxide . Just like other fossil fuels, combustion of coal produces CO2 affecting the green house effect. This even increase in global warming. This even has major impact like global warming. Don't you think such release of gases will pollute the air? Off-course Yes. Much more air quality deterioration is caused due to opencast mining in which mining operation is carried without any tunnel or shafts. Imagine how much destructive it will be? Such emission leads to serious health hazards with a rapid increase of respiratory disease such as chronic bronchitis and asthma. Really, we need to think on this otherwise the day is no far where we are left alone by nature. Within last few year production of coal is sky-rocketing. You can figure it out how the production of coal has been incresed in china in last few years. 2. Adverse impact to hydrological regime Process of mining, burning the coal and waste storage of coal pollutes the water. How? A flowing water comes into contact of coal mining activities that has exposed rocks. Such rocks contains pyrite, a sulphur bearing mineral. This mineral reacts with water forming sulphuric acid. Such runoff results into a metal rich water that is Acid mine drainage (AMD). How dreadful it would be to those aquatic plants and animals? And what about us? We too are affected as we drink that contaminated water. Other reasons that pollutes the water are erosion of mine benches , overloaded and reject dumps, failing dams and even during discharging of million litres of water itself. “Water is life” But, we have made it such that becomes dangerous to your life. How mean we are? 3. Enormous Land Disturbance Caused due to mining operation Mining operation goes through large scale excavation, creation of negligent land, removal of top soil, dumping of solid waste and cutting of roads. Usually, mine collapse in underground mining and land above it start to sink result into an interruption. News about such catastrophe is frequently heard. But, opencast mining is more destructive than underground mining. It scraps away earth and rock to get coal buried near the surface. It destroy landscapes, forest, wildlife, contaminates ground water and result into air and noise pollution. Such environmental affects are so profound that recovery of it is next to impossible. So, why we become so careless and constantly dig though it affects our environment. 4. Mining causes noise and vibration Do you like someone screaming? No Why? Because it is too unpleasant to our ears. Think of a blast or something weird sound at a high volume. How terrible it might be for our ears. Think of people living around the areas where mining activities takes place. Why? Because such mining operation produces lot of noise and vibration as well. Hundreds of tones of explosives blast in the mining area and this creates a massive noise pollution. Hearing loss of human ears is one of the major consequence of noise. Imagine how dreadful it might be? Beast in forest are more sensitive to such noise and so they are more affected than humans. Want to improve environmental sustainability in industries? There has been established many institutional bodies that offers diploma in Environmental Management. Many of them even offer excellent trainig and one of my friend has experienced best training of workplace environmental at Brisbane in Australia. Being a part of this wonderful nature, each and every individual is responsible for such destruction. Why we have become so greedy that we don't care of its frighting consequences. There is still time to save our nature otherwise it will be too late to sum up everything.
